Lesson 10 of 10
Reading other people's code
Start with the big picture: what files are there, where does it start (often main() or if __name__ == '__main__'), and what are the main functions? Then zoom into one part at a time.
Key points
- Find the entry point first
- Skim function names before details
- Run it and change one small thing
def load():
...
def show(items):
...
def main():
items = load()
show(items)
if __name__ == "__main__":
main()Your turn
