  • try...except...else高级用法

          当唔异常时,else方法也执行 
        try: # If import_module succeeds, entry is a path to an app module, # which may specify an app config class with default_app_config. # Otherwise, entry is a path to an app config class or an error. module = import_module(entry) except ImportError: # Track that importing as an app module failed. If importing as an # app config class fails too, we'll trigger the ImportError again. module = None mod_path, _, cls_name = entry.rpartition('.') # Raise the original exception when entry cannot be a path to an # app config class. if not mod_path: raise else: try: # If this works, the app module specifies an app config class. entry = module.default_app_config except AttributeError: # Otherwise, it simply uses the default app config class. return cls(entry, module) else: mod_path, _, cls_name = entry.rpartition('.')
