What are Generators in Python

 Generator functions are a special kind of function that return a lazy iterator. Lazy iterators in the sense they do not store their contents in memory.

A generator is similar to a function returning an array. A generator yields one value at a time which requires less memory.

import random

def rnd():
        #yield 5 random numbers between 1 and 50
	for i in range(5):
		yield random.randint(1, 50)

        #yield 6th random number between 1 and 10
	yield random.randint(1, 10)


for random_number in rnd():
	print("Next number is %d" %(random_number))

Output:

Next number is 39
Next number is 14
Next number is 37
Next number is 2
Next number is 3
Next number is 10
