Python is uninstalled differently in Windows and Mac. Show WindowsTo uninstall Python from Windows, follow these steps:
MacFor Python 3 and above, first, perform the following steps:
Removing additional files from the TerminalMoving the Python application to trash will not remove Python entirely. Furthermore, a built-in Python distribution may not appear in the Applications folder. So we’ll have to use the Terminal to uninstall it manually. First, open the Activity Monitor and close all processes related to Python in the Memory tab. One such process is the Python Launcher. Now we can proceed to the Terminal.
Here, you can list the current folders in your Library using the
Additionally, three more main directories have to be handled in order to remove Python. Move back to your root user directory and perform the following commands:
I have successfully installed python 3.3 on Ubuntu 12.10. Since I don’t need multiple versions of python, I want to remove the existing python 2.7. When I try to do that, using
Ubuntu warns me that there are tons of system dependent components which will also be removed. It looks really scary. So, is there a way to remove python 2.7 without removing the system dependent components, or can I direct those dependents to use python 3.3?

2 You can't.From the Ubuntu wiki / Python:
This means that a lot of base packages have hard dependencies on 2.7 and it will still take a lot of time tot get things migrated. Note that Python 3 has numerous backwards incompatible changes -- it's not a regular package upgrade. If you really want to get rid of Python 2.7, you'll have to wait for the 14.04 release, but there's no guarantee.

Python scripts that were written for 2.7, which are used to support a large amount of the system's infrastructure, won't necessarily work properly with Python 3.x. Those scripts need to be updated to work with the new version, and until that happens, you'll need to keep Python 2.7 around. This is why you notice such a large number of dependencies on the old Python - the system depends on it. Besides, there's no harm in having both versions of Python installed on the same system. And you may come across applications in the future that still use Python 2.7, so keeping it around is a good idea. answered Jul 6, 2013 at 14:32
