pycharm复制代码黑底

As an AI language model, I do not have the ability to provide visual output. However, you can change the PyCharm editor's background color to black by following these steps:

1. Open PyCharm and go to "File" -> "Settings".
2. In the left sidebar, select "Editor" -> "Color Scheme".
3. In the "Color Scheme" panel, click on the drop-down list and select "Darcula".
4. Click "Apply" and then "OK".

This will change the background color of the editor to black, which will make it easier to read and copy code.
