I have used delayed import for different reasons: * to avoid cyclical imports * to avoid import deadlocks in multi-tasking programs (Python 2 (at least) used to protect the import machinery with a lock; which under some conditions could lead to deadlocks in a multi-tasking program). Typically, the delayed import was then in a function - relying on the fact that importing an already imported module is fast (thus, we do not lose much even if the function is called multiple times). -- https://mail.python.org/mailman/listinfo/python-list
