This is not a really good idea, because all users of the previous package will see their install fails.

If you want to deprecate a package, what you can do is publish a last release with a README pointing to the new package. I did that for [python-cli-ui](https://pypi.org/project/python-cli-ui/), which is replaced by `cli-ui`

If you want to get fancy you can also:

* Add a warning printed when `setup.py` is run
* or at import time
* or replace the package by a dummy one that depends on the new name.


I&#39;m having an issue with `AppDomain.CurrentDomain.BaseDirectory`.

Sometimes the path ends with &#39;\&#39;, sometimes it doesn&#39;t and I can&#39;t find a reason for this.

It would be fine if I was using `Path.Combine` but I want to do `Directory.GetParent` and it yields different results.

My current solution is:

    var baseDir = AppDomain.CurrentDomain.BaseDirectory;
    if (!baseDir.EndsWith(&quot;\\&quot;)) baseDir += &quot;\\&quot;;

Is there another way to get the parent directory of the application?

How to ensure there is trailing directory separator in paths?

I have got few node packages which works in node.js environment and also in browser. Now I have got two seperate tests (for each environment). What is the best way to run these tests with just `npm test` command? Also I want to add these packages to travis.

I&#39;m using `mocha` and `mocha-phantomjs`.

**Node test command**

    node ./node_modules/mocha/bin/mocha ./test/node/index.js --reporter spec

**Browser test command**

    node ./node_modules/mocha-phantomjs/bin/mocha-phantomjs ./test/browser/index.html

**What I tried:**

 1. Add these commands into `npm test` script seperated with semicolon
  - *Problem:* When there is an error in first script but no error in second script, command exited with 0 and travis build passed.
 2. Let node command test in `npm test` script and create custom script for browser tests. Than add these two commands (`npm test` and `npm run-script test-browser`) into travis.yml as array.
  - *Problem:* Users have to run manually two independent test scripts.
 3. Let node command test in `npm test` script and add browser tests to `npm posttest` command. Travis.yml will than have got just one script and users will also have to run one script (everyone is happy).
  - *Problem:* It just does&#39;t feel right, so I wanted to know if there is some better way.

How to remove a package from Pypi

How do I remove a package from Pypi?
I uploaded a package to Pypi several months ago. The package is now obsolete and I'd like to formally remove it. I cannot find any documentation on how to remove my package.

Example

    s=pd.Series([5,4,3,2,1], index=[1,2,3,4,5])
    print s 
    1    5
    2    4
    3    3
    4    2
    5    1

Is there an efficient way to create a series. e.g. containing in each row the lagged values (in this example up to lag 2)

    3    [3, 4, 5]
    4    [2, 3, 4]
    5    [1, 2, 3]

This corresponds to *s=pd.Series([[3,4,5],[2,3,4],[1,2,3]], index=[3,4,5])*

How can this be done in an efficient way for dataframes with a lot of timeseries which are very long?

Thanks


**Edited after seeing the answers**

ok, at the end I implemented this function:

    def buildLaggedFeatures(s,lag=2,dropna=True):
    &#39;&#39;&#39;
    Builds a new DataFrame to facilitate regressing over all possible lagged features
    &#39;&#39;&#39;
    if type(s) is pd.DataFrame:
        new_dict={}
        for col_name in s:
            new_dict[col_name]=s[col_name]
            # create lagged Series
            for l in range(1,lag+1):
                new_dict[&#39;%s_lag%d&#39; %(col_name,l)]=s[col_name].shift(l)
        res=pd.DataFrame(new_dict,index=s.index)

    elif type(s) is pd.Series:
        the_range=range(lag+1)
        res=pd.concat([s.shift(i) for i in the_range],axis=1)
        res.columns=[&#39;lag_%d&#39; %i for i in the_range]
    else:
        print &#39;Only works for DataFrame or Series&#39;
        return None
    if dropna:
        return res.dropna()
    else:
        return res 

it produces the wished outputs and manages the naming of columns in the resulting DataFrame.

For a Series as input:

    s=pd.Series([5,4,3,2,1], index=[1,2,3,4,5])
    res=buildLaggedFeatures(s,lag=2,dropna=False)
       lag_0  lag_1  lag_2
    1      5    NaN    NaN
    2      4      5    NaN
    3      3      4      5
    4      2      3      4
    5      1      2      3

and for a DataFrame as input:

    s2=s=pd.DataFrame({&#39;a&#39;:[5,4,3,2,1], &#39;b&#39;:[50,40,30,20,10]},index=[1,2,3,4,5])
    res2=buildLaggedFeatures(s2,lag=2,dropna=True)
    
       a  a_lag1  a_lag2   b  b_lag1  b_lag2
    3  3       4       5  30      40      50
    4  2       3       4  20      30      40
    5  1       2       3  10      20      30

I have a `.txt` file in the same folder as this `.py` file and it has this in it:

    cat\n
    dog\n
    rat\n
    cow\n

How can I save a var (var = &#39;ant&#39;) to the next line of the `.txt` file?




How to write to .txt files in Python 3

I have a program which writes a user&#39;s `highscore` to a text file. The file is named by the user when they choose a `playername`. 

If the file with that specific username already exists, then the program should append to the file (so that you can see more than one `highscore`). And if a file with that username doesn&#39;t exist (for example, if the user is new), it should create a new file and write to it.

Here&#39;s the relevant, so far not working, code:

	try: 
		with open(player): #player is the varible storing the username input
			with open(player, &#39;a&#39;) as highscore:
				highscore.write(&quot;Username:&quot;, player)

	except IOError:
		with open(player + &quot;.txt&quot;, &#39;w&#39;) as highscore:
			highscore.write(&quot;Username:&quot;, player)


The above code creates a new file if it doesn&#39;t exist, and writes to it. If it exists, nothing has been appended when I check the file, and I get no errors.

I am currently learning Python so I have no idea what is going on. 

    num1 = int(input(&quot;What is your first number? &quot;))
    num2 = int(input(&quot;What is your second number? &quot;))
    num3 = int(input(&quot;What is your third number? &quot;))
    numlist = [num1, num2, num3]
    print(numlist)
    print(&quot;Now I will remove the 3rd number&quot;)
    print(numlist.pop(2) + &quot; has been removed&quot;)
    print(&quot;The list now looks like &quot; + str(numlist))

When I run the program, entering in numbers for num1, num2 and num3, it returns this:
Traceback (most recent call last):

    TypeError: unsupported operand type(s) for +: &#39;int&#39; and &#39;str&#39;


Unsupported operand type(s) for +: &#39;int&#39; and &#39;str&#39;

I&#39;m using `pip` [requirements files][1] for keeping my dependency list.

I also try to follow best practices for managing dependencies and provide precise package versions inside the requirements file. For example:

    Django==1.5.1
    lxml==3.0

**The question is:** Is there a way to tell that there are any newer package versions available in the Python Package Index for packages listed inside `requirements.txt`?

For this particular example, currently latest available versions are 1.6.2 and 3.3.4 for Django and lxml respectively.

I&#39;ve tried `pip install --upgrade -r requirements.txt`, but it says that all is up-to-date:

    $ pip install --upgrade -r requirements.txt 
    Requirement already up-to-date: Django==1.5.1 ...

Note that at this point I don&#39;t want to run an actual upgrade - I just want to see if there are any updates available.

Is there a way to use an extra Python package index (ala `pip --extra-index-url pypi.example.org mypackage`) with `setup.py` so that running `python setup.py install` can find the packages hosted on `pypi.example.org`?

How does PyPI handle case sensitivity?

For example, [this SO question](https://stackoverflow.com/questions/17460747/change-case-of-package-name-on-pypi) documents PyPI refusing a new package `foobar` if `FooBar` already exists.

Running `pip` against pypi.python.org seems to convert to the canonical case for a package:

    $ pip install django
    Downloading/unpacking django
      Downloading Django-1.7.tar.gz (7.5MB): 7.5MB downloaded

Alternatively:

    $ pip install Django
    Downloading/unpacking Django
      Downloading Django-1.7.tar.gz (7.5MB): 7.5MB downloaded

However, only some files seem to be in the canonical case in my virtualenv:

    $ ls ~/pyenvs/test_venv/lib/python2.7/site-packages/ | grep -i django
    django/
    Django-1.7-py2.7.egg-info/

What does the XML-RPC API expect? Can I always assume that http://pypi.python.org/simple/foo and http://pypi.python.org/simple/FoO will both return HTTP 200?

Is PyPI&#39;s position on case-sensitivity documented anywhere?

Is PyPI case sensitive?

I uploaded a package to PyPi using:

    python setup.py register -r pypi
    python setup.py sdist upload -r pypi


I&#39;m trying to modify the description, I wrote (**please don&#39;t edit the formatting of the following piece of code, I made it on purpose to demonstrate my problem**):

    **my plugin**
    
    This plugin enables you to ... For example:
    ```python
    @attr(section=&#39;MySection&#39;, id=1)
    def test_function(self):
        &quot;&quot;&quot;
        Bla bla bla
        &quot;&quot;&quot;
        pass
    ```

However, the text appears as it is, *without* the markdown formatting. What am I doing wrong?
