Python: Compute the depth of groups of matched nested parentheses separated by parentheses

Python Programming Puzzles: Exercise-98 with Solution

Given a string consisting of groups of matched nested parentheses separated by parentheses, write a Python program to compute the depth of each group.

Input: (()) (()) () ((()()())) 

Output:
[2, 2, 1, 3]
Input: () (()) () () () ()

Output:
[1, 2, 1, 1, 1, 1]
Input: (((((((()))))))) () (()) ((()()()))

Output:
[8, 1, 2, 3]

Sample Solution:

Python Code:

def test(parens):
    return [len(s.split(')')[0]) for s in parens.split()]

parentheses  = '(()) (()) () ((()()())) '
print("Parentheses strings:",parentheses )
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))
parentheses  = '() (()) () () () ()'
print("Parentheses strings:",parentheses )
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))
parentheses  = '(((((((()))))))) () (()) ((()()()))'
print("Parentheses strings:",parentheses )
print("\nDepth of groups of matched nested parentheses separated by parentheses:")
print(test(parentheses))  

Sample Output:

Parentheses strings: (()) (()) () ((()()())) 

Depth of groups of matched nested parentheses separated by parentheses:
[2, 2, 1, 3]
Parentheses strings: () (()) () () () ()

Depth of groups of matched nested parentheses separated by parentheses:
[1, 2, 1, 1, 1, 1]
Parentheses strings: (((((((()))))))) () (()) ((()()()))

Depth of groups of matched nested parentheses separated by parentheses:
[8, 1, 2, 3]
