# Infinite Generator Output without For Loop

While doing the Generators lesson in the Python tutorial, I tested the second program (below) after seeing the first one on the lesson. def infinite_sevens(): while True: yield 7 for i in infinite_sevens(): print(i) Output: >>> 7 7 7 ... ==================================== def infinite_sevens(): while True: yield 7 print(infinite_sevens()) Output: <generator object infinite_sevens at 0x00E95130> Why doesn’t the second program return the same output as the first?

I’m thinking it’s because all the 7’s print on a single line and there is a random? hexadecimal code for when the limit has been reached on the number of 7’s on that line. EDIT: Thanks Nikhil Dhama for the answers, but the next fn keeps the generator yielding the same value somehow.

Nikhil Dhama Here is my code: def infinite_sevens(): while True: yield 7 print(next(infinite_sevens())) def gen(): for i in range(11): yield i print ("1",next(gen())) print ("2",next(gen())) print ("3",next(gen())) print ("4", next(gen())) Output: 7 1 0 2 0 3 0 4 0 How do I get a infinite amount of lines with a 7 in each of them?

for infinite results you have to use loop, there' isn't any other way in my knowledge, and to use next properly, first intialise the iterator , iter = gen() them use next on iter, next(num). iter = infinite_sevens() then each calling of next(iter) will yield you a 7, but using for loop is the most convenient method.

use, print ( next(infinite_sevens()) it will give you values yield by generator one by one, on every calling of next fn, it will give you the next value of generator, generators are iteratable , so they can be used to iterate the loop.

def gen(): for i in range(11): yield i num = gen() print ("1",next(num)) print ("2",next(num)) print ("3",next(num)) print ("4", next(num)) execute this and you will understand it. 👆 : my bad i fixed it try it now

Roger Wang next makes the generator yield same value cuz u are yielding 7 everytime, that's why i gave you a script to understand what's happening
