常见的想当然

six.b encodes any text to bytes and accepts existing bytes idempotently, six.u coerces bytes to str, and six.byte2int coerces integer inputs while defaulting empty bytes to zero

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• six.b strictly encodes strings using latin-1 raising UnicodeEncodeError on code points above 255 and AttributeError on existing bytes rather than coercing via UTF-8 or acting idempotently
• six.u is an identity function on Python 3 that returns bytes unchanged without text coercion
• six.byte2int is mapped to itemgetter(0) which raises IndexError on empty bytes, raises TypeError on integers, and returns single-character strings when passed str
• six.indexbytes raises IndexError on empty byte sequences while supporting negative indexing on populated byte sequences
• six.ensure_binary and six.ensure_text strictly reject non-str non-bytes buffer types such as bytearray, memoryview, and None with TypeError
• six.get_function_defaults and six.get_function_closure return None rather than empty tuples when defaults or closures are absent
• six.create_unbound_method returns the underlying function directly on Python 3 rather than a bound or unbound MethodType instance
