git status 时发现有很多 .pyc 的没有被 add

.pyc 文件是什么？

Python 编译的字节码文件（.pyc 文件）**通常是 Python 解释器将 Python 源代码编译成的字节码文件。**当运行 Python 程序时，解释器会首先尝试加载这些 .pyc 文件，以加快程序的启动速度。

这些 .pyc 文件通常是由 Python 解释器根据对应的 Python 源代码生成的，它们会在 Python 源代码发生变化时自动更新。
但有时候，这些 .pyc 文件可能会被修改，例如在一些编辑器或 IDE 中保存文件时可能会触发 Python 解释器重新生成这些文件。（本文是在 vs code 中运行过项目的 python 代码）
