Deploying C program with python embedded

In this tutorial, we will explore how to deploy a C++ program that incorporates embedded Python. Combining the power of C++ for system-level programming with the flexibility of Python for scripting can be a powerful combination. We will cover the steps to embed Python in a C++ program and provide a simple example to demonstrate the integration.
Before we begin, make sure you have the following installed:
First, let's create a simple C++ program that embeds Python. Create a new file named main.cpp and add the following content:
This program initializes the Python interpreter, executes a simple Python script using PyRun_SimpleString, and then finalizes the interpreter.
Next, let's create a CMakeLists.txt file to build the C++ program. Create a file named CMakeLists.txt with the following content:
This CMakeLists.txt file uses the find_package command to locate the Python interpreter and then configures the C++ program accordingly.
Now, let's build the C++ program. Open a terminal in the project directory and run the following commands:
This will create an executable named embedded_python. Run it:
You should see the output "Hello from embedded Python!".
In this tutorial, we covered the basics of embedding Python in a C++ program. This is a simple example, but you can extend it to more complex scenarios by calling Python functions, passing data between C++ and Python, and utilizing Python libraries.
Remember to handle errors and exceptions appropriately when working with the Python C API, and ensure that the Python interpreter is initialized and finalized correctly in your application. Additionally, consider using a more robust build system and dependency management for larger projects.
