Question

我是python的新手，但是我想做的是创建一个GUI，该GUI询问用户的输入，当用户完成操作后，他们选择“提交”，将数据导出到excel电子表格。

不断出现的问题是此错误：

  File "C:/Users/ptrovato/Desktop/UserForminPython_121019.py", line 144, in <module>
    root = tk()

TypeError: 'module' object is not callable

那是我得到的错误。这是我的整个代码：

import tkinter as tk 

from openpyxl import *


# globally declare wb and sheet variable 

# opening the eTypeError: 'module' object is not callablexisting excel file 
wb = load_workbook('C:\\Users\\ptrovato\\Desktop\\Python\\excel.xlsx')

如果有人知道此修复程序，我将不胜感激！

有人可以帮助我吗？谢谢！

tkinter模块定义了一个名为Tk的类。您必须通过以下方式纠正它：

import tkinter as tk
root = tk.Tk()

或：

from tkinter import Tk  
root = Tk()

tkinter模块中的语法错误。 root = tk（）TypeError：“模块”对象不可调用
