What else did it say? You're paraphrasing a traceback into one word. Just copy/paste the whole thing, starting with the word Traceback, and ending with the error line, apparently starting with the word TypeError: For that matter, you should include the output starting with the prompt 'Line: ' > > This is my goal: > > Line: hello world > olleh dlrow > Line: extra > artxe > Line: i love python > i evol nohtyp > Line: > > This is my current code: > > line = input('Line: ') > while line != '': > line = line[len(line):0:-1] > line = line.split() > line = line.reverse() > line = (' '.join(line)) > print(line) > > Most likely your problem is that you're using Python 2.x, and therefore should be using raw_input instead of input. Of course the full traceback could point somewhere else, since it shows the line in error. After you fix the error that python shows you you'll still have at least two more. You'll need another raw_input at the end of the loop. And the call to reverse will reorder the words in the line, not the letters in each word. You need a loop or equivalent. In fact I'd recommend assigning the results ofbthe split to a different name, since it's no longer a line, but a list of words. Something like words = line.split () At that point it should be clearer that you have to loop over the words. I'll point out that the outer parentheses on the join line are redundant but harmless.
