As this question may be useful for people who also are not looking for the term &quot;code folding&quot;, I&#39;ll make my comment an answer.

As extracted from [IntelliJ IDE Web Help][2], but also worked on PyCharm CE 3.4.1:

1. Open the IDE Settings (File &gt; Settings, or Ctrl+Alt+S).
2. Under the &quot;Editor&quot; node, click &quot;General&quot; and then &quot;Code Folding&quot;. The &quot;Code Folding&quot; page is displayed.
3. In the &quot;Collapse by default list&quot;, select the check boxes to the left of the code constructs you want to be displayed collapsed. So here you can uncheck &quot;Imports&quot;. 
4. Apply changes.

I have written the code below to send headers, post parameters. The problem is that I am using SendAsync since my request can be GET or POST. How can I add POST Body to this peice of code so that if there is any post body data it gets added in the request that I make and if its simple GET or POST without body it send the request that way. Please update the code below:

    HttpClient client = new HttpClient();

	// Add a new Request Message
	HttpRequestMessage requestMessage = new HttpRequestMessage(RequestHTTPMethod, ToString());

	// Add our custom headers
	if (RequestHeader != null)
	{
		foreach (var item in RequestHeader)
		{

			requestMessage.Headers.Add(item.Key, item.Value);

		}
	}

	// Add request body


	// Send the request to the server
	HttpResponseMessage response = await client.SendAsync(requestMessage);

	// Get the response
	responseString = await response.Content.ReadAsStringAsync();

How do I make pyCharm stop hiding (unfold) my Python imports?

Every time I open a Python file PyCharm will hide all imports and shows:
<pre><code class="hljs language-arduino">import ...

within the editor.
I have to manually unfold it to see the imports. Where do I find the setting to undo auto-hiding of <code>import</code> statements?

Here is my problem, I have a dataframe like this :

     	Depr_1 	Depr_2 	Depr_3
    S3 	0 	5 	9
    S2 	4 	11 	8
    S1 	6 	11 	12
    S5 	0 	4 	11
    S4 	4 	8 	8

and I just want to calculate the mean over the full dataframe, as the following doesn&#39;t work :

    df.mean()

Then I came up with :

    df.mean().mean()

But this trick won&#39;t work for computing the standard deviation.  My final attempts were :

    df.get_values().mean()
    df.get_values().std()

Except that in the latter case, it uses mean() and std() function from numpy. It&#39;s not a problem for the mean, but it is for std, as the pandas function uses by default `ddof=1`, unlike the numpy one where `ddof=0`.


Pandas : compute mean or std (standard deviation) over entire dataframe

I have a Dataframe, df, with the following column:

    df[&#39;ArrivalDate&#39;] =
    ...
    936   2012-12-31
    938   2012-12-29
    965   2012-12-31
    966   2012-12-31
    967   2012-12-31
    968   2012-12-31
    969   2012-12-31
    970   2012-12-29
    971   2012-12-31
    972   2012-12-29
    973   2012-12-29
    ...

The elements of the column are pandas.tslib.Timestamp.

I want to just include the year and month.  I thought there would be simple way to do it, but I can&#39;t figure it out.

Here&#39;s what I&#39;ve tried:

    df[&#39;ArrivalDate&#39;].resample(&#39;M&#39;, how = &#39;mean&#39;)

I got the following error:

    Only valid with DatetimeIndex or PeriodIndex 

Then I tried:

    df[&#39;ArrivalDate&#39;].apply(lambda(x):x[:-2])

I got the following error:

    &#39;Timestamp&#39; object has no attribute &#39;__getitem__&#39; 


Any suggestions?


Edit: I sort of figured it out.  

    df.index = df[&#39;ArrivalDate&#39;]

Then, I can resample another column using the index.

But I&#39;d still like a method for reconfiguring the entire column.  Any ideas?

I am working in python and I need to convert this:

C:\folderA\folderB to C:/folderA/folderB

I have three approaches:

    dir = s.replace(&#39;\\&#39;,&#39;/&#39;)

    dir = os.path.normpath(s) 

    dir = os.path.normcase(s)

In each scenario the output has been

C:folderAfolderB

I&#39;m not sure what I am doing wrong, any suggestions?

Python Convert Back Slashes to forward slashes

Context: I am using Python with Behave (BDD).

Whether I run my tests from the command line (behave) or from a custom main(), the behavior is the same: the test runs and the only output that I see in the console is the standard BDD report.

My tests include print() statements that help me debug my code.  However, none of these print statements are being displayed in the console output when I run behave.

Is there any way we can &lt;b&gt;have &quot;behave&quot; display the print statements in our code?&lt;/b&gt;

My Main()

    config = Configuration()
    if not config.format:
        default_format = config.defaults[&quot;default_format&quot;]
        config.format = [ default_format ]
        config.verbose = True
    r = runner.Runner(config)
    r.run()

    if config.show_snippets and r.undefined_steps:
        print_undefined_step_snippets(r.undefined_steps)


My test.feature file:

    Feature: My test feature with the Behave BDD
    	Scenario: A simple test
    	Given you are happy
    	When someone says hi
    	Then you smile

My test_steps.py file:

    from behave import given, when, then, step, model

    @given(&#39;you are happy&#39;)
    def step_impl(context):
        pass

    @when (&#39;someone says {s}&#39;)
    def step_impl(context, s):
        context.message = s
        print(&quot;THIS IS NEVER DISPLAYED IN THE CONSOLE&quot;)
        pass

    @then (&#39;you smile&#39;)
    def step_impl(context):
            assert(context.message == &quot;hi&quot;)

How can I see print() statements in behave (BDD)

How do I iterate over an object&#39;s attributes in Python?

I have a class:

    class Twitt:
        def __init__(self):
            self.usernames = []
            self.names = []
            self.tweet = []
            self.imageurl = []

        def twitter_lookup(self, coordinents, radius):
            cheese = []
            twitter = Twitter(auth=auth)
            coordinents = coordinents + &quot;,&quot; + radius
            print coordinents
            query = twitter.search.tweets(q=&quot;&quot;, geocode=coordinents, rpp=10)
            for result in query[&quot;statuses&quot;]:
                self.usernames.append(result[&quot;user&quot;][&quot;screen_name&quot;])
                self.names.append(result[&#39;user&#39;][&quot;name&quot;])
                self.tweet.append(h.unescape(result[&quot;text&quot;]))
                self.imageurl.append(result[&#39;user&#39;][&quot;profile_image_url_https&quot;])

Now I can get my info by doing this:

    k = Twitt()
    k.twitter_lookup(&quot;51.5033630,-0.1276250&quot;, &quot;1mi&quot;)
    print k.names

I want to be able to do is iterate over the attributes in a for loop like so:

    for item in k:
       print item.names



 

Python iterating through object attributes

I just got set up to use pytest with Python 2.6. It has worked well so far with the exception of handling &quot;import&quot; statements: I can&#39;t seem to get pytest to respond to imports in the same way that my program does.

My directory structure is as follows:
    
    src/
        main.py
        util.py
        test/
            test_util.py
        geom/
            vector.py
            region.py
            test/
                test_vector.py
                test_region.py

To run, I call `python main.py` from src/.

In main.py, I import both vector and region with

    from geom.region import Region
    from geom.vector import Vector

In vector.py, I import region with

    from geom.region import Region

These all work fine when I run the code in a standard run. However, when I call &quot;py.test&quot; from src/, it consistently exits with import errors.

---

## Some Problems and My Solution Attempts ##

My first problem was that, when running &quot;test/test_foo.py&quot;, py.test could not &quot;import foo.py&quot; directly. I solved this by using the &quot;imp&quot; tool. In &quot;test_util.py&quot;:

    import imp
    util = imp.load_source(&quot;util&quot;, &quot;util.py&quot;)

This works great for many files. It also seems to imply that when pytest is running &quot;path/test/test_foo.py&quot; to test &quot;path/foo.py&quot;, it is based in the directory &quot;path&quot;.

However, this fails for &quot;test_vector.py&quot;. Pytest can find and import the `vector` module, but it **cannot** locate any of `vector`&#39;s imports. The following imports (from &quot;vector.py&quot;) both fail when using pytest:

    from geom.region import *
    from region import *

These both give errors of the form

    ImportError: No module named [geom.region / region]

I don&#39;t know what to do next to solve this problem; my understanding of imports in Python is limited.

**What is the proper way to handle imports when using pytest?**

---

## Edit: Extremely Hacky Solution ##

In `vector.py`, I changed the import statement from

    from geom.region import Region

to simply

    from region import Region

This makes the import relative to the directory of &quot;vector.py&quot;.

Next, in &quot;test/test_vector.py&quot;, I add the directory of &quot;vector.py&quot; to the path as follows:

    import sys, os
    sys.path.append(os.path.realpath(os.path.dirname(__file__)+&quot;/..&quot;))

This enables Python to find &quot;../region.py&quot; from &quot;geom/test/test_vector.py&quot;.

This works, but it seems extremely problematic because I am adding a ton of new directories to the path. What I&#39;m looking for is either

1) An import strategy that is compatible with pytest, or

2) An option in pytest that makes it compatible with my import strategy

So I am leaving this question open for answers of these kinds.

Importing correctly with pytest

I am having difficulty in importing a local go file into another go file.

My project structure is like something below

    -samplego
    --pkg
    --src
    ---github.com
    ----xxxx
    -----a.go
    -----b.go
    --bin

I am trying to import a.go inside b.go. I tried the following,

    import &quot;a&quot;
    import &quot;github.com/xxxx/a&quot;

None of these worked..I understand I have to meddle up with GOPATH but I couldn&#39;t get it right. Presently my GOPATH is pointing to samplego(/workspace/samplego).I get the below error

    cannot find package &quot;a&quot; in any of:
    /usr/local/go/src/pkg/a (from $GOROOT)
    /workspace/samplego/src/a (from $GOPATH)

Also, how does GOPATH work when these source files are imported into another project/module? Would the local imports be an issue then? What is the best practice in this case - is it to have just one go file in module(with associated tests)? 



importing go files in same folder

This problem happens intermittently for different libraries and different projects.
When trying to import a library, the package will be recognized, but the class name can&#39;t be resolved.
 
If on the import statement, I `right-click -&gt; Goto -&gt; the package&#39;s declaration`, I see all the decompiled classes displayed in the side pane -- Including the ones I need --
If I try to auto-complete the import statement, I notice the class I need is not featured in the dropdown.
 
I tried invalidating caches already, doesn&#39;t work. I cannot find any class conflicts -- there is no other jar file in my classpath with the same package name.
I am able to import this class into other projects.

Intellij Cannot resolve symbol on import

I&#39;ve been reading a tab-delimited data file in Windows with Pandas/Python without any problems. The data file contains notes in first three lines and then follows with a header. 

    df = pd.read_csv(myfile,sep=&#39;\t&#39;,skiprows=(0,1,2),header=(0))

I&#39;m now trying to read this file with my Mac. (My first time using Python on Mac.) I get the following error.

    pandas.parser.CParserError: Error tokenizing data. C error: Expected 1
    fields in line 8, saw 39

If set the *error_bad_lines* argument for *read_csv* to *False*, I get the following information, which continues until the end of the last row.

    Skipping line 8: expected 1 fields, saw 39
    Skipping line 9: expected 1 fields, saw 125
    Skipping line 10: expected 1 fields, saw 125
    Skipping line 11: expected 1 fields, saw 125
    Skipping line 12: expected 1 fields, saw 125
    Skipping line 13: expected 1 fields, saw 125

    Skipping line 16: expected 1 fields, saw 125
    Skipping line 17: expected 1 fields, saw 125
    ...

Do I need to specify a value for the *encoding* argument? It seems as though I shouldn&#39;t have to because reading the file works fine on Windows.

I know that it looks like duplicate, but the solutions which I found don&#39;t work for me.
I uninstalled MySQL 5.1 and installed 5.6, and I would like to import a previously exported SQL file back. But there is some function which causes an error in that export file. 
I found and ran the command:

    ../bin mysql mysql_upgrade -uroot -p --force

but if I understand, it works only when upgrade, not with install. Is there some solution for me? 

I also removed the function definition from import file and import is done. But if I want to redefine that function manually it shows me the same error &quot;can not load from mysql.proc&quot;.
Function is here:

    DELIMITER $$
    
    CREATE FUNCTION `randStr250`(length int) RETURNS varchar(250) CHARSET utf8
    begin
      declare s varchar(250);
      declare i tinyint;
      set s=&quot;&quot;;
      if (length&lt;1 or length&gt;6) then
          set s=&quot;Parameter should be in range 1-6. Your value was out of this range.&quot;;
      else
        set i=0;
        while i&lt;length do
            set s=concat(s,sha1(now()));
            set i=i+1;
        end while;
      end if;
      return s;
    end $$

Is there any easy way to delete no-more-using packages from **requirements** file?

I wrote a bash script for this task but, it doesn&#39;t work as I expected. Because, some packages are not used following their PyPI project names. For example;

    dj-database-url

package is used as 

    dj_database_url

My project has many packages in its own requirements file, so, searching them one-by-one is too messy, error-prone and takes too much time. As I searched, IDEs don&#39;t have this property, yet.

I&#39;m relatively new to using the PyCharm IDE, and have been unable to find a way to better shape the output when in a built-in console session. I&#39;m typically working with pretty wide dataframes, that would fit easily across my monitor, but the display is cutting and wrapping them much sooner than needed.

Does anyone know of a setting to change this behavior to take advantage of the full width of my screen?

Edit: I don&#39;t have enough reputation to post a screenshot, but link is below:
http://imgur.com/iiBK3iU

I would like to prevent it from wrapping after only a few columns (for example, the column &#39;ReadmitRate&#39; should be immediately to the right of &#39;SNFDaysPerSNFCase&#39;)

    $ python3.4
    &gt;&gt;&gt;import bottle # shows no import error

I have an integer value `x`, and I need to check if it is between a `start` and `end` values, so I write the following statements:


    if x &gt;= start and x &lt;= end:
        # do stuff

This statement gets underlined, and the tooltip tells me that I must 

&gt; simplify chained comparison

As far as I can tell, that comparison is about as simple as they come.  What have I missed here?

Simplify Chained Comparison

PEP8 clearly specifies 79 characters, however, PyCharm defaults to 120 and gives me the warning &quot;PEP8: line too long (... &gt; 120 characters)&quot;. 

Did previous versions of PEP8 use 120 and PyCharm not update its PEP8 checker? I couldn&#39;t find any previous versions of the PEP8 Guide, however, I can easily find previous version of the PEP8 Python scripts.

I&#39;m starting a new Python project and I&#39;m not sure which to use.

Why does PyCharm use 120 Character Lines even though PEP8 Specifies 79?

The Code folding option in RMarkdown for html documents is awesome. That option makes the programmatic methodology transparent for those who are interested, without forcing the audience to scroll through miles of code. The tight placement of code with prose and interactive graphical output makes the whole project more accessible to a wider audience, and furthermore it reduces the need for additional documentation. 

For a larger project, I&#39;m using bookdown, and it works great. The only problem is that there is no code-folding option. 
Code folding is not currently enabled in bookdown. (see https://stackoverflow.com/questions/39947867/enable-code-folding-in-bookdown )

I know I don&#39;t need an option to make it happen. I just need to paste the right code in the right place or places. But what code and where?

A viable alternative would be to put the code chunk below the chunk&#39;s outputs in the page. Or, finally, to put them as an appendix. I could do that with html but not reproducible like rbookdown.
