Getting changes into a running application is difficult. Python has not been designed to make this easy. The "reload" above is one partial way to achieve something like this. The "reload" causes the module to be reloaded. If you have changed the modules code, these changes will be reflected *inside* the reloaded module. However, other modules may have imported objects from this module (as in your "from xxx.py import yy"). To see changes in those objects, they, too, must repeat the import (otherwise, they continue to use the old, unchanged object). There is an additional approach, used e.g. by "plone.reload". In this approach, the objects are modified "in place". All usage points of the modified object will see changes. However, there are (quite severe) limitations to what changes can be made "in place". Thus, this, too, does not give a complete solution. In simple cases, one of those approaches can avoid a restart after modifications. However, in general, a restart is required. -- http://mail.python.org/mailman/listinfo/python-list
