使用PyAutoGui locateCenter函数进行Try/Except循环

Question

由于双倍增量，该代码应该通过for循环的6次迭代/从技术上讲是3次迭代来执行。相反，我收到了一个错误。

如果需要代码的其余部分，请发表意见。

对我的代码的任何批评也很感激，任何建议都会很有帮助。

我的代码：

import pyautogui
import time
import random
import keyboard
import sys

def findClickShaftFunction():
count = 1
v = 1.0
movementTime = random.uniform(0.24, 1.88)
timeToSleep = random.uniform(25.32, 62.5)    
for count in range (0,5):
try:
print("Try:", count, " Sample:", count, " Image:", count)
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts{}.png'.format(count), confidence=v)            
except TypeError:
continue
print("Try:", count+1, " Sample:", count+1, " Image:", count+1)
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts{}.png'.format(count+1), confidence=v - 0.10)                      
#else:
#count = count + 1  
#print("Unable to trace " + count)

time.sleep(timeToSleep)
pictureOfShaftsX = pictureOfShaftsX - (random.randint(2,11))
pictureOfShaftsY = pictureOfShaftsY - (random.randint(2,11))
pyautogui.moveTo(pictureOfShaftsX, pictureOfShaftsY, movementTime)
pyautogui.click()

更换后

except TypeError:

pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts{}.png'.format(count+1), confidence=v - 0.10)   

至

except TypeError:
continue

在实际定位图像之前，它会遍历整个循环。

我打算让循环做什么的例子(没有打印语句(

try:
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts0.png', confidence=0.7)      
except TypeError:
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts1.png', confidence=0.6)
try:
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts2.png', confidence=0.55)      
except TyperError:
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts3.png', confidence=0.50)      

Answer 1

据我所知，pyautogui.locateCenterOnScreen正在返回None，这就是您获得TypeError的原因。与其在except块中调用相同的方法，您可能只想将continue调用到循环的下一次迭代，如下所示：

for count in range(6):
try:
print("Try:", count, " Sample:", count, " Image:", count)
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts{}.png'.format(count), confidence=v)
except TypeError:
continue

此外，请注意，range(1,6)从1-5(包括1-5(开始—您可能希望range(6)从0-5(包括0-5(开始(总共6次迭代(。

Answer 2

我认为这是我问题的合理答案。它似乎按预期进行迭代——检查每个图像。现在，我意识到TensorFlow可能对我的应用程序更好。

如有进一步建议，不胜感激。

count = 0;
v = 0.55

movementTime = random.uniform(0.24, 1.88)
timeToSleep = random.uniform(25.32, 62.5)    
success = False
while not success:
try:
print("Try:", count, " Sample:", count, " Image:", count)
pictureOfShaftsX, pictureOfShaftsY = pyautogui.locateCenterOnScreen('C:/Users/PyAutoGui_ImageRecognition/shafts{}.png'.format(count), confidence=v)
success = True
except TypeError:
count = count + 1           
pass
