There appears to be a missing opening paren? Or a surplus closing one?
Either way this line is not in the code you sent us. It may be coming
from your IDE - which seems to be spyder.

Can you run the code from a command prompt so we see the unpolluted
Python output. IDEs are useful but they sometimes add in extra layers
that obfuscate things.

But it does look like it's this line that causes the error
so I'd try the check for emptiness as described in my previous post.
