lambda in Python

 

# def sum(x,y):

#     return x+y

# sum = lambda x,y:x+y

# Sorting list of list

a = [[2,4],[1,5],[4,3]]

# def sorting(a):

#     return a[0]

# a.sort(key=sorting)

 

a.sort(key=lambda x:x[0])

print(a)

# It will print square root of list item's

a = [2,5,7,3,4,9,1]

sq = list(map(lambda x:x*x,a))

print(sq)
