In order to start using Python, you need to have a Python distribution installed. A distribution provides a Python interpreter, and Python extensions (aka Python modules). You may have several distributions installed on your computer and you need to know how to initialize them, and which one you are using at a given time (use which python on Linux)

If you are using a Linux computer or a Mac, you should already have a default python installed. The following example shows where the python interpreter is installed on the asterix1 server (if it's in /usr/bin, it's the default python) and which version it is (version 2.6.6 compiled in May 2015)

jypeter@asterix1 - ...jypeter - 41 >which python
/usr/bin/python

jypeter@asterix1 - ...jypeter - 42 >python
Python 2.6.6 (r266:84292, May 22 2015, 08:34:51)
