Expected behaviour

No weird outputs

Actual behaviour

Steps to reproduce:

I copied and pasted java code to a newly-created python file. And then I kept getting errors from the output. Cleaning output and closing that terminal doesn't help. It pops up again. After I converted the code into Python and saved the file, I no longer receive that error message.
