lambda and annonumus function in the python

 #traditional way to use sort function .... but in one liner function

def minus(a,b):

    return a-b

print(minus(12,10))

#why use lambda ... when you want to create simple expression then use the lambda function ... example 

minus_lambda = lambda x,b:x-b

print(minus_lambda(10,12))

#example 2:- 

def sort_number(a):

    return a[1]

    

list_of_list = [[1,2],[12,1],[1000,0]]

# tradition way

# list_of_list.sort(key=sort_number)

#use lambda expression

list_of_list.sort(key=lambda x:x[1])

print(list_of_list)
