How do I trim whitespace from a string?

There are a few ways to trim whitespace from a string in Python.

The easiest way is to use the built-in str.strip() method, which removes all whitespace characters (including spaces, tabs, and newlines) from the beginning and end of a string. For example:

You can also use the str.lstrip() method to remove whitespace characters from the left side of a string, and str.rstrip() to remove them from the right side. For example:

You can also use the str.replace() method, but note that it removes all specified characters rather than just trimming leading and trailing whitespace. For example:

All the above methods work on Python 3 strings.
