Change the code style to use spaces instead of tabs:

![spaces][1]

Then select a folder you want to convert in the Project View and use `Code` | **Reformat Code**.

This only converts the tabs without changing anything else:

    Edit -&gt; Convert Indents -&gt; To Spaces

For selections, you can also convert the selection using the &quot;To spaces&quot; function. I usually just use it via the ctrl-shift-A then find &quot;To Spaces&quot; from there.

# PyCharm 2019.1

## If you want to change the general settings:

Open preferences, in macOS &lt;kbd&gt;⌘&lt;/kbd&gt;&lt;kbd&gt;;&lt;/kbd&gt; or in Windows/Linux &lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Alt&lt;/kbd&gt; + &lt;kbd&gt;S&lt;/kbd&gt;.

Go to Editor -&gt; Code Style -&gt; Python, and if you want to follow PEP-8, choose _Tab size: 4_, _Indent: 4_, and _Continuation indent: 8_ as shown below:

[![enter image description here][1]][1]


Apply the changes, and click on OK.

## If you want to apply the changes just to the current file

**Option 1:** You can choose in the navigation bar: Edit -&gt; Convert Indent -&gt; To Spaces. (see image below)

[![enter image description here][2]][2]

**Option 2:** You can execute &quot;To Spaces&quot; action by running the _Find Action_ shortcut: &lt;kbd&gt;⌘&lt;/kbd&gt;&lt;kbd&gt;⇧&lt;/kbd&gt;&lt;kbd&gt;A&lt;/kbd&gt; on macOS or &lt;kbd&gt;ctrl&lt;/kbd&gt;&lt;kbd&gt;⇧&lt;/kbd&gt;&lt;kbd&gt;A&lt;/kbd&gt; on Windows/Linux. Then type &quot;To Spaces&quot;, and run the action as shown in the image below.

**ctrl + shift + A** =&gt; open pop window to select options, select **to spaces** to convert all tabs as space, or **to tab** to convert all spaces as tab.

For me it was having a file called ~/.editorconfig that was overriding my tab settings. I removed that (surely that will bite me again someday) but it fixed my pycharm issue

Just ot note: Pycharm&#39;s ***to spaces*** function only works on indent tabs at the *beginning* of a line, not interstitial tabs *within* a line of text. for example, when you are trying to format columns in monospaced text.

I have a file which stores many JavaScript objects in JSON form and I need to read the file, create each of the objects, and do something with them (insert them into a db in my case). The JavaScript objects can be represented a format:

**Format A:**

    [{name: &#39;thing1&#39;},
    ....
    {name: &#39;thing999999999&#39;}]

or **Format B:**
 
    {name: &#39;thing1&#39;}         // &lt;== My choice.
    ...
    {name: &#39;thing999999999&#39;}

Note that the `...` indicates a lot of JSON objects. I am aware I could read the entire file into memory and then use `JSON.parse()` like this:

    fs.readFile(filePath, &#39;utf-8&#39;, function (err, fileContents) {
      if (err) throw err;
      console.log(JSON.parse(fileContents));
    });

However, the file could be really large, I would prefer to use a stream to accomplish this. The problem I see with a stream is that the file contents could be broken into data chunks at any point, so how can I use `JSON.parse()` on such objects? 

Ideally, each object would be read as a separate data chunk, but I am not sure on *how to do that*.

    var importStream = fs.createReadStream(filePath, {flags: &#39;r&#39;, encoding: &#39;utf-8&#39;});
    importStream.on(&#39;data&#39;, function(chunk) {

        var pleaseBeAJSObject = JSON.parse(chunk);           
        // insert pleaseBeAJSObject in a database
    });
    importStream.on(&#39;end&#39;, function(item) {
       console.log(&quot;Woot, imported objects into the database!&quot;);
    });*/

Note, I wish to prevent reading the entire file into memory. Time efficiency does not matter to me. Yes, I could try to read a number of objects at once and insert them all at once, but that&#39;s a performance tweak - I need a way that is guaranteed not to cause a memory overload, not matter how many objects are contained in the file. 

I can choose to use `FormatA` or `FormatB` or maybe something else, just please specify in your answer. Thanks!

I am testing Python threading with the following script:

    import threading
    
    class FirstThread (threading.Thread):
        def run (self):
            while True:
                print &#39;first&#39;
    
    class SecondThread (threading.Thread):
        def run (self):
            while True:
                print &#39;second&#39;
        
    FirstThread().start()
    SecondThread().start()

This is running in Python 2.7 on Kubuntu 11.10. &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt; will not kill it. I also tried adding a handler for system signals, but that did not help:

    import signal 
    import sys
    def signal_handler(signal, frame):
        sys.exit(0)
    signal.signal(signal.SIGINT, signal_handler)

To kill the process I am killing it by PID after sending the program to the background with &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Z&lt;/kbd&gt;, which isn&#39;t being ignored. Why is &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;C&lt;/kbd&gt; being ignored so persistently? How can I resolve this?

I am using pycharm IDE for python development it works perfectly fine for django code so suspected that converting tabs to spaces is default behaviour, however in python IDE is giving errors everywhere because it can&#39;t convert tabs to spaces automatically is there a way to achieve this.

Is there a way to receive multiple uploaded files with Flask? I&#39;ve tried the following:

    &lt;form method=&quot;POST&quot; enctype=&quot;multipart/form-data&quot; action=&quot;/upload&quot;&gt;
      &lt;input type=&quot;file&quot; name=&quot;file[]&quot; multiple=&quot;&quot;&gt;
      &lt;input type=&quot;submit&quot; value=&quot;add&quot;&gt;
    &lt;/form&gt;

And then printed the contents of `request.files[&#39;file&#39;]`:

    @app.route(&#39;/upload&#39;, methods=[&#39;POST&#39;])
    def upload():
      if not _upload_dir:
        raise ValueError(&#39;Uploads are disabled.&#39;)
    
      uploaded_file = flask.request.files[&#39;file&#39;]
      print uploaded_file
      media.add_for_upload(uploaded_file, _upload_dir)
      return flask.redirect(flask.url_for(&#39;_main&#39;))

If I upload multiple files, it only prints the first file in the set:  
  
    &lt;FileStorage: u&#39;test_file.mp3&#39; (&#39;audio/mp3&#39;)&gt;  
  
Is there a way to receive multiple files using Flask&#39;s built-in upload handling? Thanks for any help!

Uploading multiple files with Flask

I&#39;ve got the following code running on each request of a wsgi (web2py) application:


    import logging, logging.handlers
    from logging import StreamHandler, Formatter
    
    def get_configured_logger(name):
    	
        logger = logging.getLogger(name)
    
        if (len(logger.handlers) == 0):
            # This logger has no handlers, so we can assume it hasn&#39;t yet been configured (Django uses similiar trick)
    
            # === Configure logger ===
    
    		# Create Formatted StreamHandler:
    		FORMAT = &quot;%(process)s %(thread)s: %(message)s&quot;
    		formatter = logging.Formatter(fmt=FORMAT)
    		handler = logging.StreamHandler()
    		handler.setFormatter(formatter)
    		logger.addHandler(handler)
    		logger.setLevel(logging.DEBUG)
    		logger.debug(&#39;CONFIGURING LOGGER&#39;)
    
        return logger
    
    # Get app specific logger:
    logger = get_configured_logger(request.application)
    logger.debug(&quot;TEST&quot;)

It&#39;s meant to configure the logger once, with the formatted handler I want. It works, except that I&#39;m getting double entries in my stdout:

    81893 4329050112: CONFIGURING LOGGER
    DEBUG:dummy:CONFIGURING LOGGER
    81893 4329050112: TEST
    DEBUG:dummy:TEST

How do I use my new formatted handler and get rid of/hide the default one?

I want to start using Twitter&#39;s Bootstrap for a recently started Django app. I have quite a bit of experience with Django, but I&#39;m totally new to Bootstrap.

What&#39;s the best way to proceed? Are there any particular Boostrap apps for Django you would recommend or have experience with?

I understand that I could use Bootstrap directly, without any special Bootstrap-specific Django apps. However, I also read that the form rendering doesn&#39;t come out particularly well without a little server side support (rendering the Bootstrap specific CSS into the form HTML, for example).

There seem to be several projects, such as crispy forms, django-bootstrap-toolkit, etc. Looking at their project pages, I can see different levels of activity and support. If I decide to go with one of those, I would of course like to pick one which has some momentum and therefore a good likelihood of staying supported and maintained for a while. This is very important and so even if the particular app doesn&#39;t have all possible features or is a bit less flexible, it might still be a good choice, due to support/freshness, availability of examples, etc.

Thank you for any recommendations or feedback.

I&#39;m trying to rewrite some old python code with requests module.
The purpose is to upload an attachment.
The mail server requires the following specification :

    https://api.elasticemail.com/attachments/upload?username=yourusername&amp;api_key=yourapikey&amp;file=yourfilename

Old code which works:

    h = httplib2.Http()        
            resp, content = h.request(&#39;https://api.elasticemail.com/attachments/upload?username=omer&amp;api_key=b01ad0ce&amp;file=tmp.txt&#39;, 
            &quot;PUT&quot;, body=file(filepath).read(), 
            headers={&#39;content-type&#39;:&#39;text/plain&#39;} )


Didn&#39;t find how to use the body part in requests.

I managed to do the following:
 
     response = requests.put(&#39;https://api.elasticemail.com/attachments/upload&#39;,
                        data={&quot;file&quot;:filepath},                         
                         auth=(&#39;omer&#39;, &#39;b01ad0ce&#39;)                  
                         )

But have no idea how to specify the body part with the content of the file.

Thanks for your help.

How to specify python requests http put body?

    my_string = &quot;&quot;&quot;This is my first line,
    this is my second line, and...
    
    ...this is my fourth line!&quot;&quot;&quot;

How can I store the first line of that (`This is my first line,`) into a separate string? I attempted to use `.readline()` from another similar question, however I get this error:

`AttributeError: &#39;str&#39; object has no attribute &#39;readline&#39;`

How do I read the first line of a string?

I have several django projects and several different files with name `utils.py`, however pycharm treats them as simple `.txt` files with no syntax highlighting or any other kind of parsing, how can I fix this?

Pycharm utils.py not getting syntax highlight


I use python 2.7 in a virtual environment and PyCharm 2.7 (new build as of feb 07 2013).

Whenever I open a python file in it that has unambiguous errors (equivalent to compile errors in other languages, e.g. using undeclared variables, calling non-existing functions), it shows red stripes in the gutter of the file.

So, I discover errors randomly as I happened to navigate to a file that contains them. What I would really like is to be able to list all of the python errors in a separate window. The Visual Studio 2005/2008/2010/... IDE has a separate &quot;Errors&quot; view that lists all of them with file names and line numbers, and gives me the ability to click on any one of these errors and navigate directly to the source.

Does PyCharm have anything like this?


Can PyCharm list all of Python errors in a project?

Anybody here who knows, if and how I could enable  word wrap in the Python console for long lines? I can&#39;t see them as a whole, I have always to scroll the window to the righit, to get all informations. I have only 5 Buttons offered: rerun, stop, close, execute current statement, help.

(in contrast to this, in Event Log, I see buttons called &quot;Use soft wraps&quot;.)

A bottle project of mine uses Jinja2. PyCharm does not automatically recognize it and shows such lines as errors. Is there a way to make Jinja2 work?

Does PyCharm support Jinja2?

I know how to run commands with PyCharm (Tools -&gt; Run manage.py Task), but I would like to debug them also, including my commands and third party app&#39;s commands.
