Where should my .bash_profile file be for Python to update?

macos, osx-snow-leopard, python, unix

Solution

Use `python3` to run `python3`, and also restart your shell after modifying `.bash_profile` or do `source .bash_profile` to load the new settings without restarting the shell.

$ which python3
/usr/bin/python3

Example:

$ cat so.py
#!/usr/bin/python3
print("hello, world!")
$ chmod +x so.py
$ ./so.py
hello, world!

Problem

I'm using Mac OSX 10.6.8 Snow Leopard and I think I've got everything I need to install Python 3.3.2, but when I type `python` into Terminal it still says I have 2.6.1. This is because it can't find the path to the newer version, and this should be fixed by adding the following to .bash_profile: ``` PATH="/Library/Frameworks/Python.framework/Versions/3.3.2/bin:${PATH}" export PATH ``` I've already done it (and run the `cat` command on it several times just to check), but it keeps saying the same thing. I suppose my .bash_profile file and/or Python 3.3.2 folder might not be in the right directories? .bash_profile is in `/Users/mac` (home) and the Python folder is in `/Library/Frameworks/Python.framework/Versions`. Should they be somewhere else? Thanks in advance!
