In python, I am attempting the change the width of the tkinter messagebox window so that text can fit on one line.
import tkinter as tk
from tkinter import messagebox
root = tk.Tk()
messagebox.showinfo("info","this information goes beyond the width of the messagebox")
root.mainloop()
It's not possible to adjust the size of messagebox.
When to use the Message Widget
The widget can be used to display short text messages, using a single font. You can often use a plain Label instead. If you need to display text in multiple fonts, use a Text widget. -effbot
