I have no idea what you are talking about and do not know what the SGP4
or io.py files are.

It depends on which startswith() method you are looking at.
If line is a string you are correct but... if line is a bytes
object then its startwith() method expects a bytes argument.
So I suspect that line is of type bytes(*) and you must convert
it to a string or use a bytes first argument.
(*)You can check by adding a
print("type of line: ", type(line))
in your code.
