How do I import image into Python with the Tkinter GUI? [closed]

The 'hello world' image in tkinter is something like the following code:

import tkinter as tk
root = tk.Tk()

imagem = tk.PhotoImage(file="stack-overflow.png")
w = tk.Label(root, image=imagem)
w.imagem = imagem
w.pack()

root.mainloop()

Result:
