Python: How set to Entry object value from variable

Question

I try build mini application where I set image to application. It's works, but I have problem with one thing. I try using the function easy.fileopenbox get path to file and I need print it to entry object. Below my full code, where comment "<-----" shows discussed topic. Probably it's a easy case but I'm new in Python. Thanks!

from tkinter.ttk import Frame, Style, Label, Entry, Button, Combobox
from tkinter import BOTH, Tk, W, E, N, S, Canvas, NW
from PIL import Image, ImageTk
import easygui

max_h=500
max_w=900

class Okno(Frame):
    def __init__(self, parent):
        super().__init__(parent)
        self.parent=parent
        self.inicjalizuj()
    def wczytaj_ponownie(self):
        self.image=ImageTk.PhotoImage(self.im)
        self.podst.create_image(0,0, image=self.image, anchor=NW)
    def wczytaj_obraz(self):
        sciezka=easygui.fileopenbox(msg=('Wskaż odpowiedni plik'), default="C:/Users/Darkous/Desktop/tutorial/IMAGE/*.jpg")  ##self.o.get()
        print(sciezka)
        self.o=sciezka                          ## -- here i try set value from sciezka to object
        self.im=Image.open(sciezka)
        self.fbtn.config(state='normal')
        self.zbtn.config(state='normal')

    def zapisz(self):
        sciezka=self.z.get()
        if sciezka=='':
            sciezka=self.o.get()
        self.im.save(sciezka)

    def inicjalizuj(self):
        self.parent.title("Kurs Pythona")

        self.pbtn=Button(self, text="Przywróć")
        self.pbtn.grid(row=5,column=3, pady=4, padx=5, sticky=W+N)
        self.pbtn.config(state="disabled")

def main():
    gui=Tk()

Change your self.o=sciezka so that it reads

self.o.delete(0, END)
self.o.insert(0, sciezka)

The first line deletes any text inside the Entry, the second line will insert your text into the widget. The 0 in both shows that you are going from the start of the entry.

Also add END to from tkinter import BOTH, Tk, W, E, N, S, Canvas, NW so it reads from tkinter import BOTH, Tk, W, E, N, S, Canvas, NW, END.
