# Explanation

Python’s use of white space is pretty unique in comparison to other programming languages.

>The Python documentation says:
“A logical line is constructed from one or more physical lines by following the explicit or implicit line joining rules.”

And, a bit later, the documentation goes on to say this:

>“Expressions in parentheses, square brackets, or curly braces can be split over more than one physical line without using backslashes.”

Based on the documentation above, here’s what we know about white space:


- The snippet `'a' 'b'` is not valid.
- Both `('a', 'b')` and `‘a’, ‘b’` form a tuple.
- The snippet `('a' 'b')` is the string `'ab'`.

In the teaser, there is a , missing between `'green'` and `blue'`. Python will join them together as `'greenblue'`.

This is why we should use a dangling comma when we write expressions like the colors below:


Let’s find out how white spaces work in Python.
