[Pygame] Trying to import second file fails

[Destroyer1724]

I'm using the pygame Compiler and it lets me make a second file.
But I can't seem to import from it.

I've tried to import the file like usual and then everything I could think of in case OneCompiler worked differently

import second_file
import second_file.py
import "second_file"
import "second_file.py"
from second_file import *
from second_file.pt import *
from "second_file" import *
from "second_file.py" import *

But none of them did anything.

Am I doing something wrong or is this a bug?
