yield is a keyword beares the ability to turn any function into a generator. Much like the standard return keyword, but returns a generator object. It is also true that one function may observe multiple yields.
def odds(n):
odd=[i for i in range(n+1) if i%2!=0]
for i in odd:
yield i
for i in odds(8):
print(i)
The output of the above code is
1
