Question

我在更新代码方面遇到了一些问题。我可以运行我的代码，它工作正常。但是当我对代码进行调整时，输出保持与我最初运行文件时相同。如果我创建一个新的.py文件，只是复制并粘贴更新的代码，它会生成带有更新的所需输出。为什么我的原始文件没有反映输出中的更改？

我的具体示例在下面的代码中。代码按预期运行并生成输出。然后我更新它以添加“扇区”和“关闭”变量。但是，新输出不包括数据，只包括标题中的名称。是否与.pyc文件有关？

尽管这是一个古老的问题，但我想提供另一个可能的解决方案。如果该模块是您安装的东西（例如，您有setup.py文件并且已pip安装了项目），则卸载该模块可以解决该问题。事实证明，这可以解决我遇到的问题。

代码更改未反映在输出中
