python installation - what version I've installed (Mac installation)

Question

I've installed python and while checking to see which version I've installed, it seems I have 2 versions installed

I was running this command

which -a python python3

then I got this result

/usr/bin/python
/usr/local/bin/python3
/usr/bin/python3

Is it correct? I was doing something wrong? I'm confused because also while running this command

python --version 

I'm getting

Python 2.7.16

Answer 1

It is correct. You have python 2 installed in your mac

Answer 2

You can try python3 --version to see python 3 version installed.

Answer 3

You could try:

import sys
print(sys.version)

in the python console. That way you could know for sure what version you are actually using

Answer 4

by default mac os comes up with python 2 preinstalled while you only need to install python 3
