Is there anything wrong here?

Question

I am trying to complete a project named Balanced Parenthesis (You cab find it in Python Data Structures). The output shows me that everything is ok, except the last test case (It is hidden). How can I know where did I wrong? This is my code for the project:
def balanced():
#your code goes here
bal = str(input())
for i in range(len(bal)):
if bal.count("(") == bal.count(")"):
return True
else:
return False
print(balanced())

Answer 1

Some wrong cases:
)))(((
)(((()))
)(
())(
All of the above is True according to your program.
