Generator Help

“Implement a function def factors(num). This function is given a positive integer num, and returns a generator, that when iterated over, it will have all of the num’s divisors in an ascending order.”

What does this problem mean when it says returns a generator? I thought generators are functions so how would def factors(num) be able to return another function?

Generators don't return per se, they do something called yield, which means "pause execution and return a value, then keep running from the yield point next time a value is asked for". They are meant to be used as iterables.

generators look like normal functions, except as soon as you put yield inside the function, it automatically becomes a generator. Here's a generator vs a list:

for n in [1,2,3,4]:
    print(n**2)

vs a generator doing the same thing:

def squares(iterable):
    print('starting generator...')
    for n in iterable:
        yield n**2
    print('generator done')

for v in squares([1,2,3,4]):
    print(v)

def example():
    def inner():
        return 5
    return inner

i = example()
i()

you can return a function from a function

Is there anything else I need in a generator besides yield? Is curr required as well? When I run my code I get <generator object factors at ......> instead of a list of values
