[...] It's probably worth mentioning that IPython has (thanks to a user contributed implementation) search capabilities besides tab completion (which requires you to at least know the start of the string you want): In [3]: N.*nan*? N.isnan N.nan N.nan_to_num N.nanargmax N.nanargmin N.nanmax N.nanmin N.nansum In [4]: N.*inf*? N.finfo N.inf N.info N.infty N.isinf N.isneginf N.isposinf This can be very useful when querying a package for something you only vaguely know how it might be called. This just prints the list of names to stdout, you then need to actually type the one you want.
