Install Python 3.3 on Mac

I used the installer from http://www.python.org/download . The installation was successful, and it fell into the Python 3.3 folder in my application directory. I ran the “Update Shell Profile.command” script that it contained, and it added /Library/Frameworks/Python.framework/Versions/3.3/to my path. However, the version Pythonin this directory looks like 2.7.5.

/Library/Frameworks/Python.framework/Versions/3.3  ls
Headers   Python    Resources bin       include   lib       share
/Library/Frameworks/Python.framework/Versions/3.3  Python --version
Python 2.7.5

Also ls /usr/bin | grep pythonshows:

python
python-config
python2.5
python2.5-config
python2.6
python2.6-config
python2.7
python2.7-config
pythonw
pythonw2.5
pythonw2.6
pythonw2.7

What did I miss?

There are several issues here.

Firstly, you should not run the Pythonframework executable. Framework executables are not meant to be run, and it really is only a coincidence that this is happening.

virtualenv:

$ /Library/Frameworks/Python.framework/Versions/3.3/bin/python3 -m venv ~/myvenv
$ source ~/myvenv/bin/activate
(myvenv) $ curl https://bootstrap.pypa.io/get-pip.py | python
(myvenv) $ deactivate
$ source ~/myvenv/bin/activate
