#example one
@debugger
def make_greeting(name, age=None):
    if age is None:
        return f"Howday {name}!"
    else:
        return f"Whoa {name}! {age} already , you are growing uyp!"

#call make_greeting      
make_greeting("mahdi", age=22)

#example two
import math

def approximate(terms=18):
    return sum(1 / math_factorial(n) for n in range(terms))

 #call approximate
