Hey Irfan, Installed homebrew and did all the steps but it still says that the version is 2.7. 16
This is basically the code I got.

Rayyans-Air:~ rayyanahmed$ python --version
Python 2.7.16
Rayyans-Air:~ rayyanahmed$ brew link python@3.8
Linking /usr/local/Cellar/python@3.8/3.8.4...
Error: Could not symlink bin/2to3
Target /usr/local/bin/2to3
already exists. You may want to remove it:
rm '/usr/local/bin/2to3'

To force the link and overwrite all conflicting files:
brew link --overwrite python@3.8

To list all files that would be deleted:
brew link --overwrite --dry-run python@3.8
