yield statement works with for loop

def gensquares(N):
     for i in range(N):
         yield i ** 2               # resume here later

for i in gensquares(5):        # resume the function 
     print i, ':',              # print last yielded value


x = gensquares(10)

x.next()
x.next()
x.next()

def buildsquares(n):
     res = []
     for i in range(n): res.append(i**2)
     return res

for x in buildsquares(5): print x, ':',


for x in [n**2 for n in range(5)]:
     print x, ':',


for x in map((lambda x:x**2), range(5)):
     print x, ':',
