How to introduce C language library into pycharm

Introducing a C language library into PyCharm can be achieved by creating and compiling a C extension module: create a Cython file and write C code. Run "Run 'setup.py' build_ext --inplace" to compile the module. Use import to import a module and call its functions.

How to use PyCharm to introduce the C language library

Introducing the C language library into PyCharm mainly involves creating and compiling C Extension modules are implemented. Detailed steps are provided below:

Step 1: Create a C extension module

1. In PyCharm, select "File" -> "New" - > "Project".
2. In the "New Project" window, select "Python" and click "Create".
3. Right-click the project folder and select "New" -> "Cython File".

Step 2: Write a C extension module

In the created Cython file, write C code to implement the library functions you need. For example:

<code class="cython">def add_numbers(int a, int b):
    return a + b</code>

Step 3: Compile C extension module

1. In the "Run" menu, select "Run 'setup.py' build_ext --inplace ".
2. PyCharm will compile and generate the extension module file (such as "add_numbers.cpython-39-win_amd64.pyd").

Step 4: Import the C extension module

In your Python script, use the import statement to import the extension module:

<code class="python">import add_numbers

result = add_numbers.add_numbers(1, 2)
print(result)</code>

Tip:

• Make sure your C code conforms to CPython standard header files and functions.
• PyCharm will automatically load the necessary libraries (such as Python.h, numpy.h).
• You need to ensure that the Cython module is installed in the compilation environment.
• If you encounter errors, please check your C code and compilation configuration.
