Capture the numbers in this regex

Question

I have a string like this:

{{1090872, "A"}, {4281, "AA"}, {1332552, "AAACU"}, {1287145, "AABB"}}

How can I write a regex to capture the numbers. I know that I can capture the letters with: "(.*?)"

Answer 1

If you don't have number in quotes, then answer is

import re
str = '{{1090872, "A"}, {4281, "AA"}, {1332552, "AAACU"}, {1287145, "AABB"}}'
re.findall(r'\d+', str)
['1090872', '4281', '1332552', '1287145']

otherwise you can try

re.findall(r'[{},](\d+)[{},]', str)
