What is the return value of tkmb.showinfo?

The tkmb.showinfo function, which is part of the tkinter.messagebox module in Python, is used to display an informational message box. Unlike some other message box functions, tkmb.showinfo does not return a value that you can directly use in your code.

When you call tkmb.showinfo, it displays a message box with an "OK" button. The function's primary purpose is to present information to the user, not to receive input or return a specific value. After the user clicks the "OK" button, the message box closes, and the program continues its execution.

Here's a breakdown:

1. Function Purpose: tkmb.showinfo is designed to show a simple informational message to the user.

2. Return Value: The function returns None. This means that you cannot capture a value from the function call to use in your program's logic.

3. Usage: You typically use tkmb.showinfo to provide feedback to the user, such as confirming an action or displaying a status message. For example:

import tkinter as tk
from tkinter import messagebox as tkmb

root = tk.Tk()
root.withdraw() # Hide the main window

result = tkmb.showinfo("Information", "This is an informational message.")
print(result) # Output: None

root.destroy()

In the above example, the variable result will be assigned None after the message box is closed. This demonstrates that tkmb.showinfo does not provide a return value that can be used for conditional logic or data processing.

If you need to get input from the user or make decisions based on their interaction with a message box, you should use other functions from the tkinter.messagebox module, such as tkmb.askyesno, tkmb.askokcancel, or tkmb.askquestion, which do return values based on the user's choice.

In summary, tkmb.showinfo is a simple way to display information, but it does not return a value other than None.
