Called after Python is compiled into a .so file

1. Environmental preparation

      The idea is to first convert py to c code, and then compile c to so file, so you need to install the following:

      pip install cython

      sudo apt-get install python-devel

      sudo apt-get install gcc

2. Write the test program as follows:

       Create a new Test.py file with the following content:

class test:
    
    def __init__(self):
        print('init')

    def say(self):
        print ('hello')

     Create a new setup.py file with the following content:

from distutils.core import setup
from Cython.Build import cythonize

setup(ext_modules = cythonize(["Test.py"]))

3. Compile into a .so file

python setup.py build_ext

     Build/, callable so files will be generated in the current folder.

4. Call example
