python default argument code example

Example 1: python default arguments

def my_function(name, age = 20):

my_function("Mitro") # Mitro is 20 years old
my_function("Mitro", 26) #Mitro is 26 years old

Example 2: how to set a default parameter in python

def my_function(num1,num2=0):		#if num2 is not given, it will default it to zero
  return num1 + num2

print(my_function(1,2))				#prints out 3
print(my_function(4))				#prints out 4 since num2 got defaulted to 0

    return arg + kwarg

def F(a, b=None):
    if b is None:
