No, the loader is required to reuse the existing module. > Is a loader supposed to reset all the reused module's attributes and reset > the > __dict__ or does it just run the code from the module in hte __dict__? > Nothing gets reset or run. It simply reuses the existing module object. There are ways to fool the loader, for example by having a module visible in more than one file system path. The most common of these bugs is a module that tries to import the script that's started it all. Because that initial script is named __main__ internally, if you try to import it by filename you end up with two instances. -- DaveA -- https://mail.python.org/mailman/listinfo/python-list
