That blah and blah | cat should generate the same byte stream is a fine principle (though I wouldn’t be completely dogmatic about it; I think the behaviour of ls is useful). However, another important principle is that non-interactive execution like blah > file should not depend on which terminal you happen to run it from.
Python provides a simple way to adhere to both of these principles: don’t write character strings to file handles, only write byte strings.
