%s is restricted in what it will accept::- input type supports Py_buffer? use it to collect the necessary bytes - input type is something else? use its __bytes__ method; if there isn't one, raise a TypeError Examples: >>> b'%s' % b'abc' b'abc' >>> b'%s' % 3.14 Traceback (most recent call last): ... TypeError: 3.14 has no __bytes__ method >>> b'%s' % 'hello world!' Traceback (most recent call last): ...TypeError: 'hello world' has no __bytes__ method, perhaps you need to encode it?
If you produce a helpful error message for str (re: encoding), might it not be appropriate to produce a helpful error message for builtin number types (, perhaps you need a numeric format code?)?
