Tkinter - " LABEL“对象不可调用；不能以LABEL类命名对象。

Question

我正在开发一个基于tkinter的应用程序。

我试图模块化我的代码，其中每个函数都有一个特定的任务要做，有些函数只需调用其他函数。

在我的示例中，我将search按钮绑定到函数search，该函数的任务是调用其他基于API的函数，如full_name。

当我这样做时，会抛出一个错误，表示in search full_name() TypeError: 'Label' object is not callable

有趣的是

full_name()

• when中没有提到创建Label类的实例--我将search按钮绑定到函数中，full_name()，它工作得很好。但是，我想将它绑定到一个将调用所有基于API的函数的函数，到目前为止，它还不能运行

。

下面的代码如下：

#MER for frames placement through .Grid() 

#import necessary modules
from tkinter import *
from tkinter import ttk
from PIL import ImageTk, Image
from tkinter import messagebox
import requests
import json

root = Tk()
root.title("F1 Desktop Application")
root.geometry("500x600")
root.configure(bg="white")


#generate 2022 drivers-list [can scale to drivers-list by changing the]
drivers_list_request = requests.get("http://ergast.com/api/f1/2022/drivers.json")
#initialize empty-list
drivers_list = []
drivers_list_object = json.loads(drivers_list_request.content)

for elements in drivers_list_object["MRData"]["DriverTable"]["Drivers"]:
    drivers_list.append(elements["givenName"] + " " + elements["familyName"])

        for item in drivers_list:
            if v.lower() in item.lower():
                data.append(item)
        
        update(data)
        show_button(menu)

你可以自由地要求更清晰。如果有人有理由/解决办法，我将不胜感激。

Answer 1

您对标签使用了相同的名称：

full_name = Label(left_frame, text = "Full Name :")

因此它将覆盖full_name()。

为标签使用另一个名称，例如full_name_label

full_name_label = Label(left_frame, text = "Full Name :")
full_name_label.grid(row = 1, column = 0, sticky = W)
