Change Python version – CLI- linux

There can be various reasons to change the python version you
are currently using. I had to change mine so i could write in Python 2.7.xx
and run it with the terminal.

It is a fairly simple process.

First navigate and use _ls -l _ to see witch version of Python you
are currently running

to see wich versions you have installed type

you should see something similar to this

Then we are going to change the hardlink between python and the version of
you want to use with the following command. I am going to downgrade the version
here from python3 to python2.7
you can see if the version has changed with the ls -l command we used before.
