'''

1. Using generator we can execute a block of code

 based on demand by using next() function.

2. using yield keyword we can create a generator.

def gen_fun(n):

    for i in range(n):

        print('Before yield')

        yield i

        print('After yield')

gen_obj = gen_fun(10)

#print(next(gen_obj))

#print(next(gen_obj))

# print(next(gen_obj))

## Iterate based on for loop

#for i in gen_obj:

#    print(' For Loop ', i)

def gen_fun(n):

        print('Before return')

        yield n

        print(' \n After return')

        yield n

gen_obj = gen_fun(10)

print(next(gen_obj))

print(next(gen_obj))
