我正在開發一個監控計算機溫度的 python tkinter 程式，我希望它在固定時間后更新溫度值。以下功能是我曾經這樣做的：
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()
但是這種方式會達到遞回限制，所以程式會在一段時間后停止。我希望它不斷更新值，我該怎么辦？不知道改了after()會不會好點。但是如果我使用after()，tkinter 視窗會凍結一段時間，所以我不想使用它。謝謝你。

在這個用例中遞回是不夠的，請改用回圈。
Tkinter in particular has got a method which allows you to execute a function in an interval without disrupting the GUI's event loop.
Quick example:
from tkinter import *
root = Tk()
INTERVAL = 1000 # in milliseconds
def get_temp()
# ...
root.after(INTERVAL, get_temp)
get_temp()
root.mainloop()

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.
