Python is a computer language, much like Basic or C or Cobol is a language.  It's an interpretive language, and so often when you install other software, Python is installed with it.\n\nPerhaps some program that you installed also installed Python.  Several BitTorrent programs were written in Python.  It's an open source language, so consider what programs you have installed recently.  \n\nCan you delete it?  Most likely.  But there's a good chance that something won't run - probably just a software package that you picked up along the way.  But if something stops running, you can always re-install Python.\n\nSee http://www.python.org
