Python tkinter open new window with prompt button

Here is the shortest possible solution to your question. The solution works in python 2.x. For python 3.x, change the import to "tkinter" and not to "Tkinter":

import Tkinter as tk

def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

      

        
        
        
      

    

This is not what I recommend as an example of good coding style, but it does illustrate the basic concepts: a button with a command and a function that creates a window.
