Python provides a summary of sample code for various sorting algorithms,
In Python practice, we often encounter sorting problems, such as ranking search results (there is no Google or other search engines if there is no sorting). Of course, there are countless such examples. "Data Structure" also takes a lot of space to explain sorting. Some time ago, due to the

Of course, the premise is that the template content is controllable. Although this scenario is not common, it is inevitable that programmers will neglec

Some developers has claimed that Python are more productive than Java. It's dangerous to make such a claim, because it could take several days to prove that thoroughly. From a high level view, Java was statically typed, which means all variable names has to be explicitly declared. In contrast, Python is dynamically typed, which means declaration are not required. There is a huge debate between dynamic typin
This article mainly introduces the sample code for implementing various sorting algorithms in Python. In fact, Python is a very good advanced language for getting started with algorithms. If you need it, refer to the Python practice, we often encounter sorting problems, such as sorting the search results (there are no
implementation of the Python language interpreter, not the language itself. In fact, the Gil is a very coarse-grained lock of the interpreter, we can use a finer-grained lock to increase parallelism, and Gindo wrote a patch to cancel the Gil, but as it turns out, a fine-grained lock results in a twice-fold reduction in the performance of a single-threaded application, So finally decided to prioritize the p
This article mainly introduces various methods for debugging Python code in Linux. it is used for debugging after programming. if you need it, refer to this article as an overview of my debugging or analysis tools, not necessarily complete and comprehensive. if you know better tools, mark them in the comments.
Logs
Yes, indeed, we have to emphasize how important enough logging is to the
block continuing the same block the last line of this blockWe escaped the inner block?? Many programming languages use special words or characters to denote the beginning of a block of code, with another word or character representing the end of a block of code, for example, the Pascal language uses begin to represent the beginning of a block of code, usin

Yes, indeed, it is important to stress that enough logging is essential to the application. You should keep track of important things, and if your records are good enough, you can save a lot of time by identifying problems from the logs.

Python is an object-oriented interpretive computer programming language, but also a powerful and perfect universal language, has more than 10 years of development history, mature and stable. Python has the richest and most powerful class library in the scripting language, enough to support most everyday applications. It has a simple, easy to learn, free, open source, portability, interpretation, object-orie
