How to get all substrings matching a regex pattern in Python

I am using RegEx in Python and I'm having some trouble to find all the substrings matching a given pattern. For example:

import re 
pattern = '\d{8}[TRWAGMYFPDXBNJZSQVHLCKE]$' 
text = 'I want to match this two: 01234567A and this 89012345B'

When I apply the RegEx, I would expect to obtain both 89012345B and 01234567A, but I am only getting the last value (89012345B). What I've tried so far is:

match = re.search(pattern, text)
print(match.group())
>>> '89012345B'

match = re.finditer(pattern, text)
print([match.group() for match in matches])
>>> ['89012345B']

match = re.findall(pattern, text)
print(match)
>>> ['89012345B']

As you can see, this only returns the last match. What am I missing? How could I get both?

`pattern = r'\b\d{8}[TRWAGMYFPDXBNJZSQVHLCKE]\b'`. `$` matches the end of string, you need a word boundary to match a whole *word*. – Wiktor Stribiżew Jun 02 '20 at 14:16

Your issue is that `$` in your pattern meant that it could only match at the end of the string. – DarrylG Jun 02 '20 at 14:18
