How to optimize the performance of Python is the main problem discussed in this paper. This article will cover the common code optimization methods, the use of performance optimization tools and how to diagnose the code performance bottlenecks, and

Original: Python Code performance Optimization TipsCommon tips for Python code optimizationCode optimization allows the program to run faster, which makes the program more efficient without changing the results of the program, and, according to the 8

Code optimization can make the program run faster. It makes the program run more efficiently without changing the program running result. According to the 80/20 principle, it usually takes 80% of the workload to implement program refactoring,

Optimization of the algorithm time complexityThe time complexity of the algorithm has the greatest impact on the execution efficiency of the program, and in Python it is possible to optimize the time complexity by selecting the appropriate data
