In Pycharm you can highlight an occurrence of cmd in your code, right click on it, select Refactor, Rename.
You can now choose a new name and a scope for the files in which Pycharm should search and carry out the replacement in. Make sure you know the implications of where this replacement will be done, because you could accidentally refactor the term "cmd" in locations you didn't mean to.

在 Pycharm 中，您可以突出显示代码中出现的 cmd，右键单击它，选择“重构”、“重命名”。
现在，您可以为 Pycharm 应在其中搜索并执行替换的文件选择一个新名称和范围。请确保您知道将在何处执行此替换的含义，因为您可能会意外地在其中重构术语“cmd”您无意的地点。
