I tried this code but I couldn't pass test case 3. Could you please tell me what possibly went wrong?

Question

def balanced(item):

items = []

for i in item :

if i == '(':

items.append(i)

elif i ==")" and len(items)>0:

items.pop()

if (items==[]):

return True

else:

return False

print(balanced(input()))

#Test case 3 not passed(hidden)

Answer 1

You forgot that if you get ")" without any "(" in a stock than it means that it can't balanced no matter what. If you add this check it should pass.

Answer 2

When your code encounters a closing parenthesis and items is empty your code does nothing. Instead it should return False and break. So you have to make changes to the elif block.

Answer 3

Herr Rozwel Yes now it works. Thank you for helping.

I don't know this challenge but I would check what happens when you get an empty String.
I guess in this case you should return False but your function returns True.
