The re module#
Python has robust support for regular expressions in the re module. There are several useful functions; we’ll focus first on
findall. Here’s an example:
And here’s its docstring:
Return a list of all non-overlapping matches in the string.
If one or more capturing groups are present in the pattern, return a list of groups; this will be a list of tuples if the pattern has more than one group.
Empty matches are included in the result.
We’ll learn more about capturing groups soon.
