So far we have just typed in single commands in the interpreter.
What about writing scripts?
Python Programs are usually stored
in files.
Python source files are saved with
the suffix .py.

The character combination #! at
the beginning of a script is called
shebang or hashbang.
The Shebang line consists of the
shebang, the name of the interpreter
and the full path of the interpretor.
