return optional argument python code example

Example 1: python optional parameters

def my_func(a = 1, b = 2, c = 3):
	print(a + b + c)
    
my_func()
#OUTPUT = 6

my_func(2)
#This changes the value of a to 2
#OUTPUT = 7

my_func(c = 2)
#This changes the value of c to 2
#OUTPUT = 5

Example 2: python print without optional argument

a = [0, 1, 2, 3, 4]
print(*a) # print 0 1 2 3 4
print('[' + ' '.join(map(str, a)) + ']') # print [0 1 2 3 4]
