Try pypy and pythonpypy.

Pypy is a python interpreter and JIT compiler. Python code performance can be greatly improved without modifying any code.

It is super easy to use. download and install the compiled Binary Package on the official website, and then specify the interpreter when running the code.

Let's try the following code.

Import timet1 = time. time () I = 10000000 while I: I-= 1 print time. time ()-t1

It's actually 25 times different!

However, pypy is not ideal for code speed-up with IO operations, but is slower in some cases.

There is also compatibility issues with third-party libraries.

In short, we need to use pypy for scenarios involving numerical computation and mass circulation.
