Python

We provide as many modules as possible that come with the current Debian GNU/Linux stable release. Nevertheless, that might not be enough for your needs since you may want to use the newest version of some module or one that is not part of Debian.

Since Python 2.6 there is an easy way to install missing or outdated modules in your home through easy_install.

How to use easy_install

Command line help:	`easy_install --help`
Online documentation:	http://packages.python.org/distribute/easy_install.html
Install a new module:	`easy_install --user MODULENAME`
Update an existing module:	`easy_install --user -U MODULENAME`

Modules will be installed in your home within ~/.local/. You do not need to adapt the PYTHONPATH environment variable since python will look for modules in this directory automatically.

== Installing other versions of Python with pyenv==

You can of course install other versions of Python in your home. A very comfortable way of doing that is by using pyenv. Here is a short install howto. Further down you find links to documentation etc.

Install pyenv:

curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash

Add the following three lines to your ~/.bashrc:

export PATH="$HOME/.pyenv/bin:$PATH"
eval "$(pyenv init -)" 
eval "$(pyenv virtualenv-init -)"

Restart your shell so the path changes take effect:
```
exec $SHELL
```
Install some python version, e.g. for python 2.7.7:
```
pyenv install 2.7.7
pyenv rehash
```
Make sure that this new python version will be used when you run python. You only need to run this command once:
```
pyenv global 2.7.7
```
In order to update pyenv run:
```
pyenv update
```

Installation of custom (non easy_install-able) Python modules in the home directory of a user

We are sometimes asked for newer version of Python modules. We do no longer build Python modules in SEPP as the requests for modules and their versions is too widespread to keep these modules maintainable.

On this page we will list some bash-snippets that install some often requested modules in a users home.
