根据用户输入动态更改标签文本

我正在尝试用2个python文件创建一个应用程序，第一个读取用户输入（从python shell或直接通过键盘通过pynput-keyboard之类的模块）并将其存储在变量中（按空格键后）。然后，它将原始字符串和新的转换字符串发送到gui的标签。

第二个创建具有两个标签和两个按钮的gui，并获取从第一个文件传递来的变量，并基于此变量更改标签（这些按钮用于在数据库的后续步骤中插入数据）。

我已经创建了gui和python脚本来读取输入，但是我正在努力将此变量传递给第二个脚本并动态更改标签。

请参阅上面的代码示例。

read_user_input.py

import keyboard
import gui

def transform_string(string):
    if len(string)>0:
        return string[0:len(string)-1]
    else:
        return "0"

def logging_function():
    string = ""

    while(True):
        event = keyboard.read_event()
        if (str(event)[-5:-1] == "down"):
            key_pressed = ((str(event).rsplit(' ', 1))[0])[14:]

            if (key_pressed == "space"):
                """PASS THIS string AND transform_string TO OUR GUI's LABELS"""
                print("Pass to gui's labels")
            else:
                string = string + key_pressed




logging_function()
