What will be displayed on the screen as a result of executing the code?

In this code, a generator function f_g0 is defined, which returns a generator when called.

def f_g0():
    yield 43
    return 66

print(f_g0())

When calling f_g0(), the function does not execute immediately but returns a generator object. Therefore, print(f_g0()) will output something like:

<generator object f_g0 at 0x7f8b2c3d1e50>

That is, a generator object will be printed, not the number 43 or 66.

If you iterate over the generator, for example, like this:

for value in f_g0():
    print(value)

it will output:

43

return 66 in the generator is used to terminate and pass a value to StopIteration, but this value is not displayed directly during iteration.
