Using Python3 v3.8.5 on Windows... when running x12valid.py (v2.3.3) specifically, down stack in x12file.py, any line with:
self.fd_out.write(out) results in "TypeError: a bytes-like object is required, not 'str'".

Hack to force self.fd_out.write(bytes(out, encoding='ascii')) opens up a can of worms in downstream processing as there is bytes to string conversion needed if the hack is applied - so that is not the simple fix.

I am still debugging - but I assume that wherever x12valid.py code calls x12file.X12Writer - the "src_file_obj" needs to have the correct mode as tempfile._TemporaryFileWrapper. If anyone who knows the code base better can suggest the quick fix, I can try it and apply and do a pull request. Otherwise, given extra time (aka boredeom) and/or an urgent need to get x12valid working - hopefully can figure it out.

In x12valid.py, making this change:
- fd_997 = tempfile.TemporaryFile()
+ fd_997 = tempfile.TemporaryFile(mode='r+')
seems to work.
