I'm trying to write a program on Python that would plot a function defined by the user on the entry box. I am using matplotlib with tkinter and I have a defined interval on x within I wish to plot the function defined by the user. The problem is how to get the function the user inputs and read it as a command. I'd like for instance, that when the user types y = x* *2 (or y = np.sin(x), etc.) on the entry, the command is understood as a logical expression instead of as a string "x**2" that will generate an error. Is there any way to do this? Any help is welcomed.

I'm using Tkinter in Python to create a planner. I'm trying to figure out how to pass variables from one window/class to another, using Tkinter buttons. For example, how do I introduce the string variable 'user_input' in 'StartPage' to the 'CalendarToday' window. The button that directs the user to the 'CalendarToday' page from the start page is 'btn_today'. Is there any way to make this button pass the user_input variable to the 'CalendarToday' class?

Someone suggested I do it via this method but that is not working either, here is the full thing. So this script runs in background.js
