How do I read binary C++ protobuf data using Python protobuf?

Answer 1

I'm not an expert with Python, but you can pass the result of a file.read() operation into message.ParseFromString(...) without having to build a new string type or anything.

Answer 2

Python strings can contain any character, i.e. they are capable of holding "binary" data directly. There should be no need to convert from string to "binary".
