Null Bytes in source code?

[MCMXCIII]

I tried to run server.py and i am always met with the following error

Traceback (most recent call last):
File "server.py", line 17, in
from SpookFlare.lib import sfhta,sfvba
ValueError: source code string cannot contain null bytes

I tried looking in the file to find the nullbytes but couldnt find anything.

So far I have attempted to use sed to try to resolved this issue to attmept to remove the null bytes. But no matter what I do I still have nullbytes. I am sure this is something simpl I missed. Any help would be appreciated.

I think It might actually be my editor I will return after using a different editor
