Python recursive limit and how to keep monitoring something

Question

I am working on a python tkinter program that monitoring computer temperature, and I want it to update the temperature value after a fixed time. the following function is what I used to do that:

    def update():
        get_temp()#the function that get the computer temperature value, like cpu temperature.
        ...
    def upd():
        update()
        time.sleep(0.3)
        upd()#recursive call function.

    upd()

but this way will hit the recursive limit, so the program will stops after a period of time. I want it to keep updating the value, what should I do? I don't know if I change it to after() it will be better or not. but if I use after(), the tkinter window will freeze a while, so I don't want to use it. Thank you.

Answer 1

It needs loop. It should be:

def update():
    get_temp()#the function that get the computer temperature value, like cpu temperature.
    ...

def upd():
    while True:#needs a while true here and don't call upd() in this function.
        update()
        time.sleep(0.3)

upd()#this upd() is outside the function upd(),it used to start the function.

Thanks to everyone who helped me.
