[Tutor] python scripting using "./"

[Flynn, Stephen (L & P - IT)]

What is your Python executable called? You refer to it as "python" on
the command line but your "#!" line in your script refers to the
executable as "python3.1". tried it with just "python" in the #! Line?

Check the output of 'ls -al /usr/local/bin/pytho*'...

I am trying to do script in python using "./"
