No, having each module contain all of the necessary imports for itself -is- good practice. While it might seem more convenient to define all of your imports in one place, what you're really doing is injecting -all- references to - all- imported items into -every- module. Having a global soup of imported items like such is much, much harder to control for unexpected name conflicts. Ideally, you want each module's namespace to -only- contain references to the external entities it's actually using. This not only makes each module self-contained and more open to independent re-use, it makes them -incredibly- easier to debug. Please don't confuse temporary convenience with good practice. -- http://mail.python.org/mailman/listinfo/python-list
