4.1. Introduction to generators
First, be sure that the generator is an iterator. The generator has the next method and has the same behavior as the
The generator is an iterator, and it is not just an iterator. However, there are not many uses outside the iterator, so we can say it out loud: the generator provides a convenient way to customize the iterator.

The generator and yield keywords may be one of the most powerful and difficult-to-understand concepts in Python (perhaps none), but it does not prevent yield from becoming the most powerful keyword in python, which is very difficult for beginners to

1. Imagine a scene: Imagine, I want 100 primes, and then add and sum them. The usual idea is to find a tool (function) that can provide at least 100 primes at a time, and let it give me the 100 primes (return a list with 100 primes at a time). For 10
When we write the Nodejs program, we often use the callback function to process the returned data after an operation is completed, and I simply understand that it is asynchronous programming.If there is a lot of action, then the nesting of callbacks
Simple generators have many advantages. In addition to the process of expressing a class of problems in a more natural way, the generator has greatly improved many inefficiencies. In Python, function calls are expensive, and in addition to other
This note records your understanding of Python's generator functions and yield expressions.1. Generator FunctionsThe generator functions syntax supported by Python allows us to define a function that behaves like a iterator, which can be used in
