zsh: command not found: python3

and when I type which python

python: aliased to python3

actually I prefer return to python 2.7 or if someone know how can I fix this :c

Answer 1

Go into your .zshrc file. Is there a line that reads:

alias python='python3'

If so, remove that line. Else, check if you can run python2, python2.7, or something like that. If so, then just hack and add the line

alias python='python2'

Or whatever your python2 is. Else, type

sudo apt-get install python2.7

Or whatever is the appropriate method for installing programs on your system.
