Python: Separate Parentheses Groups Perfectly

Python Programming Puzzles: Exercise-10 with Solution

Given a string consisting of whitespace and groups of matched parentheses, write a Python program to split it into groups of perfectly matched parentheses without any whitespace.

Input: 
( ()) ((()()())) (()) ()
Output:
['(())', '((()()()))', '(())', '()']

Input: 
() (( ( )() (  )) ) ( ())
Output:
['()', '((()()()))', '(())']

Sample Solution:

Python Code:

def test(combined):
   ls = []
   s2 = ""
   for s in combined.replace(' ', ''):
       s2 += s
       if s2.count("(") == s2.count(")"):
           ls.append(s2)
           s2 = ""
   return ls
combined = '( ()) ((()()())) (()) ()'
print("Parentheses string:")
print(combined)
print("Separate parentheses groups of the said string:")
print(test(combined))
combined = '() (( ( )() (  )) ) ( ())'
print("\nParentheses string:")
print(combined)
print("Separate parentheses groups of the said string:")
print(test(combined))

Sample Output:

Parentheses string:
( ()) ((()()())) (()) ()
Separate parentheses groups of the said string:
['(())', '((()()()))', '(())', '()']

Parentheses string:
() (( ( )() (  )) ) ( ())
Separate parentheses groups of the said string:
['()', '((()()()))', '(())']

Python: Tips of the Day

Clamps num within the inclusive range specified by the boundary values x and y:

Example:

def tips_clamp_num(num,x,y):
  return max(min(num, max(x, y)), min(x, y))
print(tips_clamp_num(2, 4, 6))
print(tips_clamp_num(1, -1, -6))

Output:
