FYI, instead of trying to do exhaustive type checking in _check_type(), you can just rely on duck typing and catch the TypeError: >>> str(b"a", "utf-8") 'a' >>> str(bytearray(b"a"), "utf-8") 'a' >>> str(memoryview(b"a"), "utf-8") 'a' >>> str(1, "utf-8") Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: coercing to str: need string or buffer, int found
