Make Python script globally executable

Question

Let\'s say I\'ve got this one-line Python module called say_hello.py.

print \'Hello World\'

How can I make the script executab

Answer 1

General *nix answer

First line of script should look something like:

#!/usr/bin/python

although the exact path may be different on your system. Then, make the script executable and put it somewhere in your PATH.

Answer 2

Add as the first line of your script:

#!/usr/bin/env python

or, for a python3 script:

#!/usr/bin/env python3

The shell (actually the kernel) will use the first Python/Python3 interpreter found in your $PATH.
