Before starting the course, I asked the students to fill out a questionnaire that reflected their understanding of some of the concepts in Python. Some topics ("If/else Control Flow" or "definition and use functions") are not problematic for most

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

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

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

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

PHP5.5 introduces the concept of an iterative generator, the concept of iteration is already in PHP, but the iterative generator is a new feature of PHP, similar to the iterative generator in Python3, to see how the PHP5.5 Iteration Builder is

Simple generators have many advantages. In addition to being able to express the process of a class of problems in a more natural way, the generator greatly improves many inefficiencies. In Python, function calls are expensive; In addition to other

faster Efficiency-The simplest code generator implementation Why you need a code generator. When the work needs to copy and paste frequently to write the program, the better choice may be to write a code generator to generate the basic content,
