Heh, don't print docstrings. Use pydoc.

$ ( export PAGER=cat && pydoc3 str.isdecimal && pydoc3 str.isdigit )
Help on method_descriptor in str:

str.isdecimal = isdecimal(...)
    S.isdecimal() -> bool

    Return True if there are only decimal characters in S,
    False otherwise.

Help on method_descriptor in str:

str.isdigit = isdigit(...)
    S.isdigit() -> bool

    Return True if all characters in S are digits
    and there is at least one character in S, False otherwise.

Although pydoc is still really bad compared to the web/reST
documentation. (This has been noted by others.)

By the way, is it worth filing a bug report on the wording of
str.isdecimal()? It seems to imply that ''.isdecimal() should be true.
(It isn't.) Especially when compared like that to isdigit, which makes
a point of noting this particular edge case.
