This article mainly introduces the advanced usage analysis of the iterator and generator in Python. the generator is a type of iterator in Python. here we will talk about generating expressions, chain generators, and other in-depth content, for more

Advanced Usage Analysis of the iterator and generator in Python, python Generator Iterator An iterator is an object attached to the iteration protocol. It basically means that it has a next method. When called, it returns the next item in the

I am very excited about the new features discussed today, because this feature is the most magical feature of ES6. What does this "magic" mean? For beginners, this feature is completely different from the previous JS, and even some obscure. In a

1. FunctionsUse DEF statements to define functions:def add(x, y): return x + yA function body is a series of statements that are executed when a function is called. The method of calling a function is to add a parameter after the function name.

A new function is added to the ES6 standard: arrow function (arrowhead). x => x *x the arrow above is equivalent to: function (x) {return x*x; } The arrow function acts as an anonymous function and simplifies the definition of the

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

The difference between sort, sorted, reverse, reversed!!! The first thing that error should distinguish is that sort and reverse are a way to list. strings, tuples, dictionaries, and collections do not have these two methods. and sorted and reversed

5. Using the StringBuilder classString the length of the string object is fixed, and its contents cannot be changed and edited. Each time a new string is concatenated and generated using the "+" connector, a new string object is created in memory
