# Who can solve ??

Parentheses are balanced, if all opening parentheses have their corresponding closing parentheses. Given an expression as input, we need to find out whether the parentheses are balanced or not. For example, "(x+y)*(z-2*(6))" is balanced, while "7-(3(2*9))4) (1" is not balanced. The problem can be solved using a stack. Push each opening parenthesis to the stack and pop the last inserted opening parenthesis whenever a closing parenthesis is encountered. If the closing bracket does not correspond to the opening bracket, then stop and say that the brackets are not balanced. Also, after checking all the parentheses, we need to check the stack to be empty -- if it's not empty, then the parentheses are not balanced. Implement the balanced() function to return True if the parentheses in the given expression are balanced, and False if not. Sample Input: (a( ) eee) ) Sample Output: False

Muhammad if donâ€™t know how to code how did you get 89% through python data structures and 100% through python basics? If i donâ€™t understand something in a course i go back a little and try again i also use YouTube videos to try explain the subject, maybe you can try that?

Muhammad This looks like homework. It is customary to attach your code attempt when trying to resolve a problem like this

Muhammad and also I don't see any needs to use stack if your task is just to check if a parentheses string balanced or not,.. so try your attempt and then if you face other difficulties poste it here..

Right the way i would solve is is Count the "(" with .find"()" and find ")(" see if it == even number etc.. idk how it would work but thats how i would go about. Not on python data yet
