Scrapy is built up on Twisted, a python platform for the developing of network applications in an asynchronous (non-blocking) approach. This means that, while running in a single thread, a Scrapy application does not block while waiting data arrival from the network. Instead, it continues to process any task that requires CPU attention. Then, when data arrives, a callback function is called with this data as parameter. This is why this kind of code is also called event-driven or callback-based.
