今天小编就为大家分享一篇pycharm设置当前工作目录的操作(working directory)，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
【Python】新手入门学习：什么是工作目录，在实际编程中如何应用
m0_58477260的博客

工作目录是Python编程中一个非常重要的概念。了解如何查看和设置工作目录，以及如何在不同的目录下使用相对路径和绝对路径，对于编写健壮和可维护的Python程序至关重要。通过掌握这些知识，你可以更加自信地处理文件和目录操作，避免常见的路径问题，并编写出更加高效和可靠的代码。随着你对Python编程的深入学习，你将发现工作目录的概念在很多场景下都会用到，无论是数据处理、项目管理还是模块导入。因此，花一些时间来熟悉和掌握这个概念是非常值得的。

pycharm 设置working directory 我从GitHub上clone了一个别人的项目setDroid。在运行代码的时候，更改了一些路径，发现有点不对劲，总是会有错误。于是我在代码中添加了 print(os.getcwd()) 来输出当前目录，发现当前目录是：/Users/XXX/MY_project/setDroid/Tool。那么现在我希望我的当前工作目录是：Users/XXX/MY_project/setDroid。我需要做的是更改 working directory。 参看一篇优快云
