When I run the Python code, it does generate a .txt file smoothly but it is not able to render the signal and I get an error:
UserWarning: Animation was deleted without rendering anything. This is most likely unintended. To prevent deletion, assign the Animation to a variable that exists for as long as you need the Animation.
