If you cut from the middle, it may affect readers' understanding and evaluation of your research results.

2. Avoid misunderstandings and mistakes: Interception of the code from the middle may lead to errors in the semantics and logic of the code, and readers may misunderstand the meaning and function of the code, thus affecting the understanding and evaluation of your research results.

3. Follow academic norms and moral requirements: The academic community has strict academic norms and moral requirements, and the integrity and authenticity of research results should be guaranteed. If the code is intercepted in the paper, it may violate academic norms and moral requirements and affect the credibility and academic value of the paper.
