To introduce the Python Pyd module, you can follow these steps:

  1. Firstly, make sure that Cython and Python development tools are installed. They can be installed by running the following command:
pip install Cython
  1. Create a source code file for a Pyd module, such as example.pyd.
  2. Write Python code in the source code file and use Cython syntax for comments and type declarations. For example:
# example.pyd
def add(a: int, b: int) -> int:
    return a + b
  1. Compile the source code into an extension module using Cython in the command line. Run the following command:
cython example.pyd

This will create a C source file named example.c that is the same as the source code file.

  1. Compile the C source file into a shared library using Python’s development tools (such as gcc). Run the following command:
gcc -shared -o example.so example.c

This will create a shared library file named example.so.

  1. Now, you can import and use the Pyd module in Python code. For example:
import example

result = example.add(3, 4)
print(result)  # 输出: 7

Please note that the extension of shared library files may vary on different operating systems. For example, on Windows, the extension for library files is typically .pyd instead of .so. Therefore, adjustments may be necessary when compiling shared libraries based on the requirements of the operating system.

I hope the above information is helpful to you!
