[Tutor] Invoking Python

[bhaaluu]

You can create a Python script on a *nix system and run it with:

$ python threeplusfour.py

You can place a shebang line as the first line of the script, which points
to the python interpreter:

#!/usr/bin/python
print("Hello, world!\n")

Save the file, then make it an executable with:

$ chmod u+x threeplusfour.py

Then execute it with:

$ ./threeplusfour.py

Why the dot-slash? Here is a good explanation:

You can also create a Python script and place it in a directory that is
included in your PATH (echo $PATH). Once the executable script is in
a directory in your PATH, you can execute it with:

$ threeplusfour.py

Happy Programming!
