Which version of Python do I have installed?

Question

I have to run a Python script on a Windows server. How can I know which version of Python I have, and does it even really matter? I was thinking of updating to latest version of Python.

Answer 1

Open a command prompt window (press Windows+R, type in cmd, and hit enter). Type python.exe

Answer 2

in a Python IDE just copy and paste in the following code and run it (the version will come up in the output area)

import sys
print(sys.version)

Answer 3

you can get version of python by using following command

python --version

You can even get version of any package installed in venv using pip freeze as

pip freeze | grep "package name"

or using python interpreter as

In [1]: import django
In [2]: django.VERSION
Out[2]: (1, 6, 1, 'final', 0)
