Python Learning Notes

1. Import is only valid for the first time.

Run it by import a file at the interaction prompt, but only once in a session, and the next import is simply to return the loaded module. To force Python to reload the code for a file, you need to call the function reload (module) for this purpose.

2. Use a simple for loop instead of while or range

" Hello World "  for inch print c                           # concise for inprint s[i]            #  Complex i = 0whileprint s[i]; I+=1            # complex
