Why the code das not work for one case

Question

I wrote code for a challenge in the data structures course and the code works good for all the cases except one.
This is the code:
def balanced(expression):
#your code goes here

open = 0
close = 0
expression = list(expression )
for c in expression:
if c == "(":
open += 1
elif c == ")":
close += 1
if close == open :
return True
else :
return False

print(balanced(input()))

(I need to find duplicate parentheses)

Answer 1

Suppose the test case was ")(" – your code would return True but it should return False

Answer 2

please read the task description carefully. it gives some very helpful hints how this can be implemented in detail

happy coding!
