This article mainly introduces "python simulated keyboard input and the process of switching keyboard layout analysis". In daily operation, I believe many people have doubts about the process of python simulated keyboard input and switching keyboard layout. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts of "python simulated keyboard input and the process of switching keyboard layout". Next, please follow the editor to study!

Toggle keyboard layout

This function is packaged into a decorator, and the original keyboard layout is restored after the function is executed.
