What is the benefit of using Generators ?

Question

Is there any example which can prove that a particular program can be written in a simpler way by using generators ?

Answer 1

#Normal :
class Solo:
def __init__(self, max = 0):
self.max = max
def __iter__(self):
self.n = 0
return self
def __next__(self):
if self.n > self.max:
raise StopIteration
result = 2 ** self.n
self.n += 1
return result
===================
#Generator :
def SoloGen(max = 0):
n = 0
while n < max:
yield 2 ** n
n += 1

#Easy 2 implement
#memory efficient
