Why For reasons of efficiency as well as consistency, Python only reads the module file on the first time a module is imported. If it didn't, in a program consisting of many modules where each one imports the same basic module, the -basic module would be parsed and re-parsed many times. To force rereading of a +basic module would be parsed and re-parsed many times. To force re-reading of a changed module, do this:: - import imp + import importlib import modname - imp.reload(modname) + importlib.reload(modname) Warning: this technique is not 100% fool-proof. In particular, modules containing statements like :: @@ -1755,10 +1755,10 @@ module contains class definitions, existing class instances will *not* be updated to use the new class definition. This can result in the following paradoxical behaviour: - >>> import imp + >>> import importlib >>> import cls >>> c = cls.C() # Create an instance of C - >>> imp.reload(cls) + >>> importlib.reload(cls) <module 'cls' from 'cls.py'> >>> isinstance(c, cls.C) # isinstance is false?!?
