Python Versions on Mac

Question

I\'m working on Mac Os 10.7 (Lion) and I have some questions:

1. What is the pre-installed version of python on Lion?
2. I\'ve been working on this computer for

Answer 1

1. Lion uses Python 2.7 by default; 2.5 and 2.6 are also available.

2. /Library/Frameworks/Python.framework does not exist on a stock install of Lion. My guess is that you've ended up with this by installing some application.

3. The default Python install is primarily installed in /System/Library/Frameworks/Python.framework, although some components are located elsewhere.

4. Yes - you can brew install python@2 to get a Python 2.7 separate from the system version, or brew install python to get Python 3.7. Both will install to /usr/local, like any other Homebrew recipe.

Answer 2

1. I think that is Python 2.7 but you can check typing python on a command terminal. It will tell you the version.
2. I couldn't tell that you can deleting it, because I don't know what it has... can you give more info about it?
3. Just type "which python" and it will tell you
4. You should use virtualenv and pip: http://jontourage.com/2011/02/09/virtualenv-pip-basics/
