You're actually working with floats; Python has a quite separate decimal module, and it's not what you're doing here. It's confusing for those of us who know that you're actually working in binary floating point :) Secondly: An image is a really bad way to capture an error message. Instead of saying "it is not working" and uploading a screenshot to imgur, just copy and paste the exception into the body of the email. Thirdly: If you're working iteratively, keep the files as simple as possible, and if you can do this as one-liners in Idle's interactive mode, that's probably the easiest way to show us what's happening. Don't bury all of them in together into a single program. As to your actual issue... it's a little unclear, because the system's interpretation of what you've written is completely different from yours - due to one misplaced bracket. >>> str(format(number), ',.2f')) You want to format the number .2f, not str the formatted number .2f. I think you can figure it out from there :) ChrisA
