01) Understanding how it works :

addition = lambda x,y : x+Y
result = addition(3,4)

02) lambda function with map() function

numbers = [ 1 , 2 , 3 , 4 ]
square_num = map(lambda x : x**2 , numbers)

03) lambda function with filter() function

numbers = [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]
greater_than_five = filter(lambda x : x>5 , numbers)
