如何匹配嵌套的函数字符串？

import re

def match_nested_functions(string):
    pattern = r'\b\w+\((?:[^()]+|\([^()]*\))*\)'
    matches = re.findall(pattern, string)
    return matches

string = "foo(bar(baz), qux)"
matches = match_nested_functions(string)
print(matches)

['baz', 'bar(baz)', 'foo(bar(baz), qux)']
