One of my favorite things about Mac OS X is Homebrew. It sets Python up in the most charming way where you can just type “python” for python 2.7 & “python3” for python 3.5. I’m on Windows now though (sadly), and need both versions on my computer. Yet when I used the official installers, I found I could only access Python 2. Python 3.5 Solves this with comes with this Py Launcher, but there’s an alternate solution too
Symbolic Links (aka – Terminal Shortcuts):
You have to place the Symbolic Link in one of the folders in your Path*. Personally, I just placed it in the same folder as the original Python Binaries. Here’s the code:
> cd c:\bin
> mklink python25.exe c:\python25\python.exe
(Note: the first line is whatever folder you want the link to exist in. The second line is mklink link_name.exe path_to_file_that_is_linked_to.exe)
In the example, this means you can now type “python25” into terminal & it will run python 2.5 … you can do this for any and all versions of python
*Your Path File is a list of all the directories that Windows checks when you type a command into your Terminal.
