What I mean is once you have working scripts

connect_to_mongodb()
while True:
    record = make_fake_data()
    insert_record_into_mongodb(record)

and

connect_to_server()
while True:
    record = read_record_from_server()
    print(record)

you can combine the code in a third script to

connect_to_server()
connect_to_mongodb()
while True:
    record = read_record_from_server()
    insert_record_into_mongodb(record)

and be fairly sure that the combination works, too.
