how to extract a multiple substring from inside a string in Python?

Question

I refer to the question how to extract a substring from inside a string in Python? and have further question.

What if my string is something like:

gfgfdAAA1234ZZZsddgAAA4567ZZZuijjk

I want to extract 1234 and 4567, is it stored as a list?

Answer 1

import re
re.findall('\d+','gfgfdAAA1234ZZZsddgAAA4567ZZZuijjk')
['1234', '4567']

Answer 2

Let me know if I'm not understanding you correctly, but you can certainly extract these substrings as a list, though you do it slightly differently:

>>> import re
>>> text = 'gfgfdAAA1234ZZZsddgAAA4567ZZZuijjk'
>>> re.findall(r'[0-9]{4}', text)
['1234', '4567']
