The "DeferredList" is a class in the "twisted.internet.defer" module of Python's Twisted library. It represents a collection of deferred objects and allows for the coordination and handling of multiple deferreds.
A deferred object is an asynchronous computation that may succeed or fail, and the DeferredList class provides a mechanism to track the progress and results of multiple deferreds simultaneously. It is particularly useful when dealing with parallel or concurrent operations.
The DeferredList class allows you to add deferred objects to the collection and register a callback function that will be called when all the deferreds have either succeeded or failed. This enables you to perform some action once all the computations are complete, such as aggregating the results or executing additional logic.
Furthermore, the DeferredList class supports error propagation, meaning that if any of the deferreds in the collection fail, the failure will be propagated to the callback function. This allows you to handle exceptions and failures in a centralized manner.
Overall, the DeferredList class in Twisted's Python library provides a convenient way to manage and coordinate multiple asynchronous operations using deferred objects.
