Add a little complexity:

#############################
# file useless_msg2.py
def generate_useless_msg():
    while True:
        yield "hi, I'm learning Python !"

def main():
    msg_list = generate_useless_msg()
    for msg in msg_list:
        print msg

if __name__ == '__main__':
    main()
#############################

Hmmm... You need python 2.3 to run this...

Enjoy!
