How do I determine which version of Python I'm using?

Question

I'm using the MySQL Workbench to run MySQL 5.7 and I have Python installed.

Answer 1

Run the following commands and whichever gives an output is the version you have:

• Python 2: python --version
• Python 3: python3 --version

Note: You can have both installed and used independently by simply adding the shebang to the top of the Python script to indicate which you want to use. Example:

python 2 script: #!/usr/bin/python
python 3 script: #!/usr/bin/python3

Answer 2

I am on Babun (Cygwin fork) and when I type python --version it displays the version.

$ python --version
Python 2.7.8

On a sidenote:

if you have different versions of Python installed, you can switch between them using a shell alias (add to your .bashrc) for example:

alias python=/usr/local/bin/python2.7

Please do use this carefully, as it might break things. Switching between 2.6 and 2.7 should normally work.
