Or you can go to the genuine doco; always worth checking. It is possible for a class to inherit from multiple classes, and the optional arguments let you choose between them.

0MR4N , it doesn't always need to be self. If you are wanting to call a method from a parent class of one of your class' objects, you would specify that object instead of self.
Another possibility is that you are importing a class from a library, and it has a private parent class that you don't want to import. If you wanted to access a class or static method from that private parent, you would put the class you have imported in that second argument, fitting the "or type" definition for the argument.

Here's a pretty good explanation of super()

If you had thoroughly read the link I provided you'd have already known the answer. 😉

def balanced(expression):
#your code goes here
print(balanced(input()))
Balanced Parentheses
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

Make an algorithm that reads several numbers and tells you how many of those numbers
between 100 and 200 were entered. When the value 0 (zero) is read, the algorithm
must cease its execution. (someone answer
