This article does not involve optimization because it requires that you have a good grasp of the internal mechanism of the matching engine.Regular expression languages are relatively small and limited (limited functionality), so not all string processing can be done with regular expressions. Of course, some tasks can be done with regular expressions, but the final expression becom

Python has an extremely rich and stable data science tool environment. Unfortunately, for those who do not know the environment is like a jungle (cue snake joke). In this article, I will step by step guide you how to get into this pydata jungle. You might ask, how about a lot of the existing Pydata package recommendation lists? I think it would be unbearable for a novice to offer too many choices. So there

Python implements sorting algorithms: Quick sort, bubble sort, insert sort, select Sort, heap sort, merge sort, and Hill sort Python implements fast sorting principleFirst select any data (usually the first number of the array) as the key data, and then put all the smaller than it in front of it, all bigger than it put behind it, this process is called a fast
