2. The execution efficiency of the psyco

script is somewhat unsatisfactory. Although it is not difficult to optimize, if there is a simple method, there is almost no need to modify the source. code, it's certainly worth paying attention to. The magic of psyco is that it only needs to call just two lines of code at the entrance of the code, and the performance can be improved by 40% or more. It can be said to be an immediate effect!

If your customer thinks your program is a bit slow, please don't rush to optimize the code. psyco may make him change his mind immediately. psyco can be called Python's JIT. It has a lot of potential that can be tapped. If there is not much time left for you to optimize performance, please read its manual immediately. There are many tricks to easily optimize performance.

The above are some commonly used third-party libraries
