I have tried this on the Codecademy interpreter/emulator (I'm not sure which they use) and the repl.it interpreter, but for the same result. If anyone could find the glitch in my code, please let me know. Thanks!

Hm. I fixed the indentation like you said, and it worked fine. The only reason I changed the indentation to what you saw in the first place is because Codecademy's Python engine registered an error. However, repl.it accepted the script. I have concluded that the original mistake was actually on the Codecademy site instead of my script. Thanks for helping me out.
