用 pyautogui找图的时候，因为我要依次找多个图片，所以想依次把文件名赋值给变量，然后在Part = pyautogui.locateOnScreen(‘pk.png', confidence=0.5) 语句中用变量来代替文件名，但是我尝试后发现会报错，是我写错了还是它不能这样用？
对了，图片文件已经跟py文件放在同一文件夹下了。
源代码如下：
# 测试区域截图功能-1
#对后台窗口截图
import win32gui, win32ui, win32con,win32api
from PIL import Image
import cv2
import numpy
import pyautogui
from ctypes import windll, byref, c_ubyte
from ctypes.wintypes import RECT
import numpy as np
#获取后台窗口的句柄，注意后台窗口不能最小化
hwnd=win32gui.FindWindow(0,'阴阳师-网易游戏') # 根据窗口名称获取句柄
print('获取窗口句柄 %d 成功。' %(hwnd))
#获取句柄窗口的大小信息
x, y, x1, y1 = win32gui.GetWindowRect(hwnd)
width = x1 - x
height = y1 - y
print('成功获取窗口尺寸。')
# #把文件路径赋值给变量
# def bianliang():
# #斗技
# info = 'E:/代码/python/'
# filename = 'jiacheng.png'
# pk = info + filename
# #准备
# info = 'E:/代码/python/'
# filename = 'zhunbei.png'
# zhunbei = info + filename
def zhaotu():
#-------找图------
Part = pyautogui.locateOnScreen(pk, confidence=0.5) ####### 这一行的文件名用变量就会报错 ########
zhongxin = pyautogui.center(Part) # 找图的中心点
print(zhongxin)
# 找图还包括
# locateOnScreen(image): 返回屏幕上与image匹配的第一个实例点
# locateCenterOnScreen(image): 返回屏幕上与image匹配的第一个实例的中心点
# locateAllOnScreen(image)： 返回generator
# region：缩小查找区域，可提升找图速度
pyautogui.locateOnScreen(pk, region=(x, y, width, height)) ######### 还有这里也用了变量 ##########
pyautogui.click(zhongxin.x,zhongxin.y,button='left') # 点击
print('点击成功！')
ii = 1
abc = ("'pk.png'","'jiacheng.png'","'shoudong.png'","'jiesuan.png'")
while ii < 10:
for aa in abc:
if aa == abc[1]:
# info = 'E:/代码/python/'
# filename = 'jiacheng.png'
# pk = info + filename
pk = abc[1]
print(aa)
zhaotu()
elif aa == 'zhunbei.png':
print(aa)
zhaotu(aa)
else:
print(aa)
终端运行结果如下：

你为什么要在文件的文本框内再加一层引号？把引号去掉。
建议去熟悉一下变量的性质
