A cursory look at Objects/moduleobject.c suggests that it'd be one more lookup in the error handling in module_getattro, pretty doable. ChrisA Why not go one step further and let the user know there is/was another pandas waiting in line to be imported.... "maybe you intended to import module of the same name at these other locations". This would be an expensive disk read if you did it at the time the exception was raised, but what if at import time python kept a reference around to the other candidate locations of a module name that would have been imported? Most of the time those locations would not have changed. And furthermore to reduce any hit to performance you could have it only site this information for this helpful error message if the import came from the local directory and not somewhere like site packages. Though I don't know how people would feel about different error messages bubbling up depending on where a module was imported from....
