For example, in Python square brackets, [and ], are used for lists; curly braces, {and }, are used for dictionaries; and parentheses, (and ), are used for tuples and arithmetic expressions. It’s possible to mix symbols as long as each maintains its One approach to check balanced parentheses is to use stack. Each time, when an open parentheses is encountered push it in the stack, and when closed parenthesis is encountered, match it with the top of stack and pop it. If stack is empty at the end, return Balanced otherwise, Unbalanced. open_list = [" ["," {"," ("] To give a rough recursive explanation, balance of the parenthesis usually means that any word, if restricted to parenthesis, either.
