File is too large when submitting

Hey guys. I’m new here and am trying to submit my first ever solution for the problem “Shell game”. However, when submitting my solution, I get the following error: “File too large: 278068 bytes”. What can I do to fix this? My file is only 27 lines, so I’m not sure what the problem is. I’m using the USACO guide IDE.

Can you provide a link to your code?

I think I figured it out. I pressed CTRL + S to save the file, because that’s what I normally use on a different IDE, but that gives you a giant MHTML file that’s filled with text. I needed to press “download file” from a set of options instead in order to get the py file.
