What sort of arguments do they take?
You should be able to infer this from what the corresponding str or list methods do -- always substituting bytes for those, and int for the single element.
Other bytes objects? (Then the literal is more important.)
Unicode? With an extra decoding argument?
The only way to use unicode is to use bytes(, ). The others methods barf on Unicode.
Sequences of integers? Is startswith(500) False or a ValueException?
TypeError.
Single integers? startswith(ord('A'))
TypeError (this is the same as the previous.)
+ Note the conspicuous absence of .isupper(), .upper(), and friends.
This does force the use of more regular expressions, by ruling out data.upper().startswith("ERROR:")
Yeah, over dinner we started leaning towards perhaps supporting at least lower() and upper() (but acting only on the 2x26 ASCII letters).
