2. psyco

The execution efficiency of the script is somewhat poor, although optimization is not difficult, but if there is a simple method, almost do not need to modify the source code, it is certainly worth paying attention to. The magic of psyco is that it only needs to call just two lines of code at the entrance to the code, and performance can be improved by 40% or more, which is instant!

If your client thinks your program is a little slow, please don't rush to optimize the code, psyco may be able to change his mind immediately. Psyco is Python's jit and has a lot of potential to tap into, and if there's not much time left to optimize your performance, read its manual right away, and there are plenty of tricks to easily optimize performance.

These are some of the third-party libraries commonly used by python
