Article Introduction：The emergence of chatbots based on generative artificial intelligence tools, such as ChatGPT, Bard, and how to use AI tools for academic research has caused huge controversy. However, at the same time, the value of AI-generated code for scientific research has been ignored. . Compared with the plagiarism problem caused by ChatGPT generated text, using AI to copy code is obviously less controversial. Open science even encourages "code sharing" and "code reuse", and it is also very convenient to trace the source. For example, "import" is used in python to import dependencies. The package counts as a reference. In a review article recently published in Nature, the author team discussed three potential capabilities of ChatGPT in the field of scientific programming, including brainstorming, decomposing complex tasks, and processing simple tasks.
