I guess this is kind of like mocking for testing. I have a simple module that's imported in a number of other spots in my program. There's a condition in the OS/filesystem where I'd like to import a polymorphically compatible variant of the same module. Can this be accomplished in a sort of once-and-only once spot?
For example, consider something like this: client/ module_a module_a_prime lib/ paths lib_a lib_b ... model/ model_a model_b ... top_level_a top_level_b ... I have a number of imports of module_a. I have a paths module that isolates all of my file system access, and that's where the determination can be made which one to use, so I tried to do something like: def dynamic_client_module(): return client.module_a_prime if the_condition_occurs else client.module_a Hoping that I could do something like from lib import paths import paths.dynamic_client_module() But this seems to not work. Import can only take real modules? Not programatic ones? Is there a Not-Too-Evil-Way(tm) to add a level of programmatic indirection in the import declarations? Or some other trick from a different angle? -- https://mail.python.org/mailman/listinfo/python-list
