Just because mydown has imported requests, doesn't mean it is visible everywhere. Each module is a separate namespace, so that requests = "something" inside module A doesn't break import requests inside module B. Inside mydown you import requests, but you still need to import it in the interactive interpreter too. Don't worry, the second import will be very fast, once a module is imported once the second and subsequent times is very quick. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
