Tkinter 'module' object is not callable

Question

im getting the above error when i run this code snippet. Im trying to error proof user input by creating an error window when the user enters a value not in a dataframe. the code im running is below

import tkinter as tk
import tkinter.messagebox
import pandas as pd
root= tk.TK()
def customer_search():
    try:
        search = int(entry1.get())
    except ValueError:
        tk.messagebox("that customer doesnt exist, please enter a new number")      #error proofing has to be added tomorrow
        search = int(entry1.get())

    k = df.loc[df['UniqueID'] == search]
    k.to_excel("dashboard.xlsx")
    df.to_excel("check.xlsx")


canvas1 = tk.Canvas(root, width=400, height=300)
canvas1.pack()

entry1 = tk.Entry(root)
canvas1.create_window(200, 140, window=entry1)

button1 = tk.Button(text='Enter a customer for analysis', command=customer_search)
button1.pack()

the error i get is as follows

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:/Users/....py", line 42, in customer_search
    search = int(entry1.get())
ValueError: invalid literal for int() with base 10: 'a'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:Users...__init__.py", line 1705, in __call__
    return self.func(*args)
  File "C:/Users....py", line 44, in customer_search
    tk.messagebox("that customer doesnt exist, please enter a new number")      #error proofing has to be added tomorrow
TypeError: 'module' object is not callable

Process finished with exit code 0

Answer 1

tk.messagebox is a module containing multiple dialogs, you probably want to use tk.messagebox.showerror("Info Title", "Info content").

Other dialogs are showwarning and showinfo, depending on your use case.

Answer 2

tk.messagebox is a module not a function. A basic difference between modules and functions is that:

You can’t call modules, i.e., you can’t do module(). (This is precisely the mistake you are making.)
You can call functions, i.e., you can do function(). (This is what you should be doing instead.)

You need to do it this way (in customer_search):

tk.messagebox.showerror("Title here", "that customer doesnt exist, please enter a new number")

where tk.messagebox.showerror is a function in tk.messagebox module.
