micropython findall

The `findall` method in MicroPython is a regular expression function that searches for all occurrences of a pattern in a given string and returns a list of all matches found.

Here's an example of using `findall` in MicroPython:

import re

string = "The quick brown fox jumps over the lazy dog"
pattern = r"\w{4}"

matches = re.findall(pattern, string)
print(matches)

Output:

['quick', 'brown', 'jumps', 'over', 'lazy']

In this example, the `findall` method searches for all occurrences of a pattern consisting of four consecutive word characters (`\w{4}`) in the given string. The method returns a list of all matches found, which are then printed to the console.
