How to set up a Python environment in PyCharm?

Setting up the Python environment in PyCharm can be done by following these steps:

1. Open PyCharm, click on the “File” option in the menu bar, then select “Settings”.
2. In the pop-up window, expand the “Project” option and select “Project Interpreter”.
3. On the right-hand side dropdown menu, you can see the installed Python interpreters. To add a new interpreter, click on the “Add” button on the right side.
4. 在弹出的窗口中，可以选择要添加的解释器类型。可以选择已安装的Python解释器，也可以选择“Virtualenv Environment”（虚拟环境）或“Conda Environment”（Conda环境）来创建一个新的环境。
5. After selecting the interpreter type, you can choose the Python interpreter to use. If the installed interpreter is not shown in the list, you can click on the “…” button on the right to manually specify the path of the interpreter.
6. After completing the above steps, click on the “OK” button to save the settings.

Once set up, PyCharm will use the chosen Python interpreter to run and debug the project. If different Python interpreters are needed for different projects, they can be set in the settings of each project.
