How to insert an image in Python?

How do I solve this error?

  

"could not open" 3.gif ": no such file or directory"

I created a folder in which I saved the work and the image but followed the error.

The code I have to implement the image:

import numpy as np
import random

if __name__ == "__main__":
    print ("Hello World")

from tkinter import *
from tkinter import ttk, font



raiz = Tk() # Creación de la ventana principal
raiz.geometry('655x435') # ancho x alto
raiz.configure(bg = 'red')
raiz.title('Matriz')
fuente = font.Font(weight='bold')

#ima=PhotoImage(file="3.gif")

#lbiman=label(raiz,imagen=ima).place(x=5,y=5)

campo=[]

boton1 = ttk.Button(raiz, text="crear matriz", padding=(5,5))
boton1.grid(padx=5, pady=30,sticky=(  E, W))
