New submission from Rob Cliffe <rob.cli...@btinternet.com>:
help() on an exception class lists the method resolution order, which is in
effect the class inheritance hierarchy. E.g. help(ArithmeticError) lists
ArithmeticError, StandardError, Exception, BaseException, __builtin__.object.
It struck me it would help to find my way around if it also listed the builtin
SUBclasses (if any). Something like:
Built-in subclasses:
FloatingPointError
OverflowError
ZeroDivisionError
In fact why not do it for any class, not just exceptions?
I attach a patched version of pydoc.py - tested but only on my PC which is
running Python 2.5 under Windows XP. I have added lines 1129-1148 to the
docclass method of the TextDoc class (and flagged them # [RAC] ).
(I don't pretend to understand the magic where __builtins__ is a dictionary
when pydoc.py is run but becomes a module later on. Never mind - the patch
works (I believe).)
For consistency, a similar patch would also have to be made to the docclass
nethod of the HTMLDoc class (which outputs HTML rather than plain text). I
have not attempted this as I don't know how it is called and hence how to test
any patch, but it should be straightforward for anyone with the know-how.
