Simple. Here are the steps:
1. Remove the Python 2.7 framework
sudo rm -rf /Library/Frameworks/Python.framework/Versions/2.7
2. Remove the Python 2.7 applications directory
sudo rm -rf “/Applications/Python 2.7”
3. Remove the symbolic links in /usr/local/bin
When I tried creating my first PyDev project in Eclipse on OS X Lion, I was asked to configure my interpreter as it was not listed. And when I did the “Auto Config” option, it came be with the following error:
The fix was simply manually adding this Python path: /Library/Frameworks/Python.framework/Versions/2.7/bin and selecting “Python.” Eclipse then found the appropriate /Lib files and everything worked.
As of now, only the Python 2.6.5 Documentation is published for download on the python.org website; however, I was interested in downloading Python 3.1.1’s Documentation.
After some searching, I found it; so sharing it to the world. It’s at: http://www.python.org/ftp/python/doc/3.1.1/. (I personally chose the “python-3.1.1-docs-pdf-letter” and it printed fine.)
Googling this didn’t really help me decide, but after stumbling on an interview by O’Relly with Guido van Rossum, the creator of Python, I decided to go with Python 3.x.
Here’s what he said that set my mind:
If you’re learning Python for the first time, 3.0 is a great way to learn the language. There’s a couple of things that trip over beginners have been removed.
It’s easier to learn the differences between 2.6 and 3.0 after you’ve learned 3.0 than to go the other way.
Happy learning and programming!
