You can move put try-catch outside of the generator!

in_generator.py

import time

def generate():
    try:
        for i in range(5):
            time.sleep(0.5)
            yield i
    finally:
        print("My jos is done, clock out!")


gen = generate()
for x in gen:
    print(x)

out_generator.py

import time


def generate():
    for i in range(5):
        time.sleep(0.5)
        yield i


try:
    gen = generate()
finally:
    print("My jos is done, clock out!")

for x in gen:
    print(x)

They are different!
