Problem with buttons

[Barrowman]

You need to bind the buttons to an event and call the command differently.
Here is the code as I have altered it.

from tkinter import *
import tkinter as tk
 
def write_slogan(event):
    v= event.widget['text']
    print(v)
 
root = tk.Tk()
frame = tk.Frame(root)
frame.pack()

for k in range(0,11,1):
    btn = tk.Button(frame, text=str(k))
    btn.bind("<Button-1>", write_slogan)
    btn.pack(side=tk.LEFT)
 
root.mainloop()
