将列表从 python function 导入 tkinter GUI 的最佳方法是什么

Question

我有以下 pyhton 脚本正在运行并返回一些列表：

如何使用 python 脚本（第一个代码）的 output 在 GUI（第二个代码）中触发一个动作（第一个代码）是否有一般的方法来做到这一点

我使用 Pycharm 作为代码编辑器，我使用 Pycharm 内置函数运行脚本

import cv2
import time
import os
import HandTrackingModule as htm


def fcf():

wCam, hCam = 640, 480

cap = cv2.VideoCapture(0)
cap.set(3, wCam)
cap.set(4, hCam)

folderPath = "FingerImages"
myList = os.listdir(folderPath)
#print(myList)
overlayList = []
for imPath in myList:
    image = cv2.imread(f'{folderPath}/{imPath}')
    # print(f'{folderPath}/{imPath}')
    overlayList.append(image)

#print(len(overlayList))
pTime = 0

detector = htm.handDetector(detectionCon=0.75)

tipIds = [4, 8, 12, 16, 20]

while True:
    success, img = cap.read()
    img = detector.findHands(img)
    lmList = detector.findPosition(img, draw=False)
    ts = time.time()
    #print(lmList)


    if len(lmList) != 0:
        fingers = []
        satisfied = []
        neutral = []
        unsatisfied = []
        # Thumb
        if lmList[tipIds[0]][1] > lmList[tipIds[0] - 1][1]:
            fingers.append(1)
        else:
            fingers.append(0)

        # 4 Fingers
        for id in range(1, 5):
            if lmList[tipIds[id]][2] < lmList[tipIds[id] - 2][2]:
                fingers.append(1)
            else:
                fingers.append(0)

        #print(fingers)
        totalFingers = fingers.count(1)
        #print(totalFingers)

       


        #h, w, c = overlayList[totalFingers - 1].shape
        #img[0:h, 0:w] = overlayList[totalFingers - 1]

        #cv2.rectangle(img, (20, 225), (170, 425), (0, 255, 0), cv2.FILLED)
        #cv2.putText(img, str(totalFingers), (45, 375), cv2.FONT_HERSHEY_PLAIN,
#                    10, (255, 0, 0), 25)


    cTime = time.time()
    fps = 1 / (cTime - pTime)
    pTime = cTime

    cv2.putText(img, f'FPS: {int(fps)}', (400, 70), cv2.FONT_HERSHEY_PLAIN,
                3, (255, 0, 0), 3)

    cv2.imshow("Image", img)
    cv2.waitKey(1)

if __name__=='main':
    fcf()

我有以下 tkinter GUI：

from tkinter import *
from PIL import ImageTk, Image
from FingerCounter import *

root = Tk()

root.title('Customer Satisfaction Survey')
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
#root.geometry(f'{screen_width}x{screen_height}')
root.columnconfigure(0, weight=1)
root.columnconfigure(1, weight=1)
root.columnconfigure(2, weight=1)

#root.attributes('-fullscreen',True)

frame = Frame(root)
# Define the images
Img = ImageTk.PhotoImage(Image.open("coo.png"))
Img1 = ImageTk.PhotoImage(Image.open("Doo.png"))
Img2 = ImageTk.PhotoImage( Image.open("Wave.png"))
#
ImgLabel00 = Label(root, text="   \n \n \n \n\n\n\n\n\n\n\n \n \n \n \n  ")
ImgLabel00.grid(row=0, column=0, padx=5, pady=5)
ImgLabel = Label(image=Img)
ImgLabel.grid(row=1, column=2, padx=5, pady=5)
ImgLabel1 = Label(image=Img1)
ImgLabel1.grid(row=1, column=0, padx=5, pady=5)
ImgLabel2 =  Label(image=Img2)
ImgLabel2.grid(row=1, column=1, padx=5, pady=5)

# craeting a label widget
myLabel = Label(root, text="      ", font=("Arial", 35))
#myLabel1 = Label(root, text="      ")
myLabel2 = Label(root, text="      ", font=("Arial", 35))
#myLabel3 = Label(root, text="      ")
myLabel4 = Label(root, text="     ", font=("Arial", 35))
#shoving it into the screen
myLabel.grid(row=2, column=0)
#myLabel1.grid(row=0, column=2)
myLabel2.grid(row=2, column=1)
#myLabel3.grid(row=0, column=6)
myLabel4.grid(row=2, column=2)




root.mainloop()

我不确定我的方法是否最佳，但这就是我的工作方式：

我采用了多线程并创建了两个线程，一个运行 Tkinter GUI，第二个线程运行 python 脚本。

python 脚本将一个 function 的 output 写入文本文件，而第一个线程上的 GUI 读取相同的文本文件并触发操作。
