python - Python 给了我很多回溯的东西是怎么回事

Question

这是我的代码

from pyautogui import * 
import pyautogui 
import time 
import keyboard 
import random
import win32api, win32con

while (1):
    if pyautogui.locateOnScreen('stickman.png', region=(150,175,350,600), grayscale=True, confidence=0.8) != None:
        print("I can see it")
        time.sleep(0.5)
else:
    print("I am unable to see it")
    time.sleep(0.5)

追溯：
