Why doesn't PDB seem to support help () for all objects like the regular Python interpreter?

It seems that running "help (object)" in PDB doesn't really work, while in a regular interpreter it works very well in most cases. This is debugging, especially on new projects, a little annoying - is there a way to fix this?

(Pdb) help(int)
*** No help on (int)

When you type help...

into pdb, it invokes its own built-in pdb command help

, which provides help with regards to using pdb.

For the help

one you are looking for, you can bypass the built-in pdb with the prefix !

:



(Pdb) !help(int)

Help on class int in module __builtin__:

class int(object)
 |  int(x=0) -> int or long
 |  int(x, base=10) -> int or long
 ...


(Pdb) help
