What is the usage of a generator in a script based on Requests?

edit

A generator in a script based on Requests is used to efficiently process large amounts of data by retrieving and streaming data in small, manageable chunks instead of retrieving and holding all the data in memory at once. This helps to reduce memory usage and improve performance, especially when working with large files or network requests with a large amount of data. The generator function in Requests produces an iterator which can iteratively yield chunks of the data, and can be used in a variety of applications, including web scraping, data extraction, and data processing.
