extract characters between parenthesis with conditions

Question

a = '{a=[],b=[],c=[ab=cd,ef=gh],d=[ij=kl],e=[]}'

How can I extract characters between parenthesis [ ] from above string that are after =. Output expected is:

'cd','gh','kl'

Answer 1

Use regex to capture the string in [] with = between

import re
result = re.findall(r'\w+=(\w+)', a)

\w+ will match all word with length 1 or more

() denote a capturing group
