Familiar with Python, using Python for database operations (1), and learning python The database has been connected in the previous lecture. As far as the database is concerned, it must be operated after the connection. However, the data named qiwsirtest is just an empty shelf and there is no operation. to operate on it, you must create a "table" in it. What is a

Synchronous vs. asynchronous Synchronous and asynchronous attention is to the message communication mechanism (synchronous communication/asynchronous communication)The so-called synchronization is that when a call is made, the call does not return until the result is obtained. But once the call returns, it gets the return value.In other words, it is the caller who actively waits for the result of the call . Instead of async, the call returns immediately after it is emitted, so no results

My friend asked me how to quickly master python. I want to write a quick Python tutorial similar to the w3cschool style by adding a variety of standard libraries and expanding libraries, on the one hand, keep the words concise, and on the other hand, gradually make it possible for readers without background to start learning from the basics. In addition, I concentrate on a small concept in every article, ho

When it comes to participle, we must generally think it is a very advanced technology, but today the author with just dozens of lines of code to get it, exclamation python is very powerful Ah! The author is also very powerful.

Python basics and python BasicsPython features 1. Easy to learn:Python has a relatively small number of keywords, and the structure is simple. It is easier to learn with a clearly defined syntax. 2. Easy to read:Python code definition is clearer. 3. Easy Maintenance:Python's success lies in that its source code is quite easy to maintain. 4. A wide range of standard libraries:One of the biggest advantag
