PYTHON ADVANCED - 08: LAMBDA

 IN THIS TUTORIAL, YOU WILL LEARN ABOUT LAMBDA:

NOTE: TRY ALL METHODS/ CODES'

#lambda arguments : expressions

# add10 = lambda x: x +10

# print(add10(5))

# def add10_func(x):

#     return x + 10

# mult = lambda x,y: x*y

# print(mult(2,7))    

# points2D = [(1,2), (3,4), (5,6), (-1,3)]

# # points2D_sorted = sorted(points2D)

# # points2D_sorted = sorted(points2D, key=lambda x: x[1])  #--> sorts by Y coordinate value

# points2D_sorted = sorted(points2D, key=lambda x: x[0] + x[1])

# print(points2D)

# print(points2D_sorted)

#map(func,seq)

# a =[1,2,3,4,5,6]

# b = map(lambda x: x*2, a)

# print(list(b))

# c = [x*2 for x in a]

# print(c)

# filter(func,seq)  --> prints only even function

# a =[1,2,3,4,5,6]

# b = filter(lambda x: x%2==0, a)

# print(list(b))

# c = [x for x in a if x%2==0]

# print(c)

#reduce(func,seq)

from functools import reduce

a = [1,2,3,4,5,6]

product_a = reduce(lambda x,y: x*y, a)

print(product_a)
