如何使用Python连续读取基于Linux的操作系统的CPU温度？

Question

I'm trying to make a program for raspberry pi, but I'm continuously switching between Mac and Raspberry Pi. Is there a way to access CPU Temp through Linux using Python. And can I make it work with tkinter ? ( tkinter being unable to properly use while loops from my knowledge

# How can I get a continuous CPU temperature reading for Linux (Mac//Raspberry Pi) using a 
def function():
    #stuff
    tkinterFrame.after(delay, function)
# im using tkinter so avoiding while loops
# need to use function .after()```

I expect a continuous output that refreshes every second.

Linux gives you the current temperature of the CPU when you read the file /sys/class/thermal/thermal_zone0/temp . You will get a single line of text with the temperature as an Integer . So you have to divide the result by 1000 to get the temperature in °C . Please take a look at this simple example which read the current time and the temperature to print both in the terminal.

import time
import datetime

while(True):
    CurrentTime = datetime.datetime.now()

    with open(r"/sys/class/thermal/thermal_zone0/temp") as File:
        CurrentTemp = File.readline()

    print(str(CurrentTime) + " - " + str(float(CurrentTemp) / 1000))

    time.sleep(1)

All you have to do now is to store the results and print them (maybe with a plot?). You can use an extra thread to do it, so your application won´t be stuck when you use some kind of delay (because you don´t need to read the temperature every millisecond - every second is enough I think).
