Write a dynamic library in C language, providing two functions, the sum of two numbers and the sum of two floating-point numbers. It's called mylib.c

Compile c function file into so dynamic library. Run the command gcc mylib.c-fpic-shared-o libtest. so, and you can see the generated library file libtest.so in the directory.

Python calls so library files. Import ctypes first, then load the so file with CDLL, and finally call the corresponding function. Save python code in pydemo.py

Execute python pydemo.py to see the running results.
