Whitespace

Whitespace is key to Python, since it is used to separate blocks of code.

Indentation

Indentation is necessary in Python to control program flow.
Even in languages where it is optional, it is best practice since it makes code more readable.

Blank lines

Sometimes blank lines can be used to make code more readable.
In Python, the guidelines are:
- Subroutines should be separated by a blank line.
- Blank lines can be used sparingly in subroutines to show sections of the subroutine.
- Other lines of code should not have blank space around them.
