I currently have python 2.7.1 installed on my Mac and there are some features of 2.7.3 that I would like to use with my current Python development. I’ve downloaded the and extracted the tar ball into my /Users/mark/Python-2.7.3 but when I run my Python script how do I tell it to use the new 2.7.3 version instead of the system installed 2.7.1?

    you could either use the interpreter you want to run the script directly:

    /Users/mark/Python-2.7.3/python2.7.3 script.py

    or set the interpreter in the shebang line:

    #!/Users/mark/Python-2.7.3/python2.7.3

    third option, prepend the path to the interpreter to the PATH variable:

    export PATH=/Users/mark/Python-2.7.3/:$PATH
