1. Use List to implement? : Conditional expression
["False", "true"] [judgment condition]
It is actually a problem of List [0] or List [1. If the condition is true, it is List [1]. If the condition is not true, It is List [0.
2. Write a
The iterator tool is very convenient and efficient when generating data. After mastering these basic methods, more iterator tools can be obtained through a simple combination. Original article: https://git.io/pytips

Give you both Var A and B, print the value of a+b, just do it!!Answer: print a+b
Give you a list L, such as l=[2,8,3,50], sort L in ascending order and output,The result of example L is [2,3,8,50]Answer: L=[2,8,3,50] L.sort() or L.sorted() print
This article mainly introduces the basic syntax of Python and analyzes in detail the concepts and usage skills of process control statements, expressions, functions, objects, types, and mathematical operations involved in the basic syntax of Python,
The bit data type is an integer, and its value can only be 0, 1, or null. This data type is used to store data with only two possible values, such as Yes, No, True, False, On, or Off. note: a data type that saves a lot of space. If you can meet your

This article mainly introduces the climbingmethod (climbingmethod) is an optimization algorithm. It generally starts from a random solution and then gradually finds an optimal solution (local optimization) then we implemented this algorithm using
Today to see Baidu know someone asked how to verify that the number within 1000 matches Goldbach conjecture, wrote aFeel more than 10000 when a bit slow ah, and Java compared to the efficiency of the point, I hope the master can give optimization
Let's say we have a task: simply test whether a computer in a local area network is connected. The IP range of these computers ranges from 192.168.0.101 to 192.168.0.200.Idea: Programming with the shell. (Linux is usually bash and Windows is a batch
This article describes how to use Python to determine prime numbers, python, which is often used for scientific computation, can handle this small problem. of course, you can refer to the subprime number or prime number as needed. In a natural

The threading module of Python provides multiple lock-related methods. the multiple threads of Python cannot be executed at the same time. Therefore, the use of locks is critical, the following is an example of how to use the thread lock in Python
Improve your Python capabilities: Understanding unit testing is the topic of testing for new programmers. They vaguely think that "unit testing" is good, and they should also do unit testing. But they do not understand the true meaning of the word.
This article is the fourth article on a large list. it was originally intended to write only three articles. it was found that some content was not clearly described, so I had to add another article. This section describes how to operate a list.
