Do I need Python to use nodejs

Using node.js is a very popular development method. It uses JavaScript as the development language and is suitable for various scenarios such as web development, back-end development, and command line tools. However, some people may be worried about whether Python is required when using node.js?

Before answering this question, let's first understand the relationship between node.js and Python. The bottom layer of Node.js is implemented in C++, not Python. Therefore, Node.js and Python have no underlying relationship, and you can use Node.js for development without Python.

However, if you need to use some Python libraries or modules, then you need to interact with Python in Node.js. In this case, you need to use some open source tools to help you achieve this. The most famous of them are Python's C extension API and Node.js' NAPI interface.

Python's C extension API allows you to write C or C++ code to extend Python and dynamically load this code in Node.js. This way you can access Python libraries and functionality through Python modules in Node.js. However, this requires you to have experience in C/C++ programming, and requires certain knowledge to use Python's C extension API.

N-API is a new interface introduced in Node.js 8.x version that allows you to use C or C++ to write interaction codes with Node.js and load them dynamically. This interface is cross-platform, so you can use it on multiple platforms. In addition, N-API also provides some convenient APIs and tools to help you write Python extensions.

If you don't want to write an extension in C or C++ to interact with Python, there are some other options. For example, you can use the Node.js child_process module to start a Python process and interact with it through the child process's stdin and stdout. Alternatively, you can use Node.js's ffi module to load a Python shared library file and call functions within it directly.

In summary, you don't need Python support when using Node.js, but if you need to use Python libraries or modules, then you need to use some tools to make them available in Node.js. No matter which method you choose, you will need to have some knowledge of C/C++ and Python. At the same time, this also demonstrates the power and flexibility of Node.js, allowing developers to choose the method that best suits them to complete the task.
