Let me offer you some hints: This sounds like only the last line is getting saved into the dict. Yet your loop is clearly going over each line. Ergo, the problem is probably in the part where you add the line to the dict. Focus on that part and see what is happening versus what you want to have happening. Double check what command you are actually giving. On Tue, Oct 30, 2012 at 6:01 PM, Brayden Zhao <[email protected]> wrote: > hello! > > I am doing my homework now and I am kinda stuck.
