我有一个VB脚本（UFT）代码，该代码会触发Python脚本以仅检查图像是否为所需颜色，而python脚本会将字符串返回给具有颜色值的VB脚本。 我能够从VB脚本调用python脚本，并且python脚本也已执行并返回了值。我的问题是无法将返回值保存在只是空白的任何变量中

下面是我的VB脚本代码，它调用python脚本

Function Verifycolor(icolor,ipath,rValue)

Dim pyr
Set pyShell = CreateObject("Wscript.Shell")
color = icolor
Imagepath = ipath
pyColorVerify = "python ""C:\Users\a272099\Desktop\Python\codes\Verifycolor.py""" & " " & color & " " & ImagePath
Set pyOperation = pyShell.Exec(pyColorVerify)
Set pyResult = pyOperation.StdOut
wait(1)
msgbox pyResult.ReadAll


pyr = pyResult.ReadAll

msgbox pyr

'Do 
'pyRet = pyResult.ReadAll
''msgbox pyReturn
'wait(1)
'Loop Until pyReturn <> empty

If pyr = rValue  Then
        Reporter.ReportEvent micPass,"Preconditions are not set to" &color& "color","preconditions are set"
    Else
        Reporter.ReportEvent micFail,"Preconditions are set  to" &color& "color","preconditions are set"
End If

msgbox pyResult.ReadAll

End Function

下面是将值返回给VB脚本（验证颜色）的python脚本

import sys
import numpy as np
import pytesseract
from PIL import Image
from pytesseract import image_to_string
import cv2
color = sys.argv[1]
src_path = sys.argv[2]
#src_path = "C:\\Users\\a291068\\Desktop\\Python\\PreconditionsImage.png"
img=cv2.imread(src_path)
img_hsv = cv2.cvtColor(img,cv2.COLOR_BGR2HSV)
if color == "RED":
    mask_red = cv2.inRange(img_hsv,(0,50,20),(5,255,255))
    if cv2.countNonZero(mask_red) > 0:
        Return = "Red is present!"
    else:
        Return = "Red is not present!"
else:
    if color == "GREEN":
        mask_green = cv2.inRange(img_hsv,(36,25,25),(70,255))
        if cv2.countNonZero(mask_green) > 0:
            Return= "Green is present!"
        else:
            Return = "Green is not present!"
print(Return) 

当python返回值时，问题在我的VB脚本中 当我执行Msgbox PyResult.Readall时，正在获取从Python返回的正确消息，即存在绿色或不存在绿色。

如果我将该值分配给任何变量，例如pyr。 pyr总是空的，什么也没有存储。

请帮助我解决将pyResult.ReadAll存储到变量中的问题，以便我可以在其他条件下使用它。

让我知道是否需要进一步的信息。
