Do you want to optimize the performance of your Python program to make it run faster or consume less memory? Before diving into any performance tuning, you should strongly consider using a technique called software profiling. It can help you decide whether optimizing the code is necessary and, if so, which parts of the code you should focus on. Sometimes, the return on investment in performance optimizations just isn’t worth the effort. If you only run your code once or […]
