generator function that yield from a list

[snippsat]

Here with re.finditer(),so it's still regex but an alternative way of using regex.

addresses = btInfo.group().split()
for idx in range(len(addresses)):

So here use @r0ng split() and range(len(addresses),together with regex.

import re

foo = "70D76320 BEG 701D135D 702D72FC END EAR0 00000000 0000000"
for match in re.finditer(r'BEG\s(.*?)\s(.*?)\s', foo):
    for idx,address in enumerate(iter(match.groups())):
        print(f'[{idx}]0x{address}')

Output:
[0]0x701D135D
[1]0x702D72FC
