CHAPTER ONE FEATURES • Use synchronization instead of callback-based method to get input • Non-declarative layout, simple and efficient • Less intrusive: old script code can be transformed into a Web service is the object itself so it can be used in combined output. Output Scope PyWebIO uses the scope model to give more control to the location of content output. The output scope is a container of output family. such as ‘iPhone’ – device.brand (str): Device brand. such as ‘Apple’ – device.model (str): Device model. such as ‘iPhone’ • user_language (str): Language used by the user’s operating system.

Output Scope PyWebIO uses the scope model to give more control to the location of content output. The output area of PyWebIO can be divided accept coroutine functions as task functions. The session based on the coroutine is a single-thread model, which means that all sessions run in a single thread. For IO-bound tasks, coroutines take up fewer
