Package topo :: Package command :: Module basic :: Class ImportErrorObject

Class ImportErrorObject

Raises an ImportError on any attempt to access an attribute, call, or get an item.

Useful to delay an ImportError until the point of use, thus allowing e.g. a class attribute to contain something from a non-core external module (e.g. pylab).

Delaying an ImportError until the point of use allows users to be informed of the possibility of having various extra functions on installation of a missing package.
