root.title("PASSWORD GENERATOR")

delkahesla = Entry(root, width=35)
delkahesla.insert(0, "How many letters would you like?")
Psymboly = Entry(root, width=35)
Psymboly.insert(0, "How many symbols would you like?")
Pcisla = Entry(root, width=35)
Pcisla.insert(0, "How many numbers would you like?")

def kliknuti():
    x = int(delkahesla.get())
    y = int(Psymboly.get())
    z = int(Pcisla.get())
    for i in range(x):
    heslo.append(random.choice(abeceda))
    for i in range(y):
    heslo.append(random.choice(symboly))
    for i in range(z):
    heslo.append(random.choice(cisla))

    random.shuffle(heslo)
    STRheslo =  ' '.join(heslo)
    vysledek.insert(0, STRheslo)
    return heslo

vysledek = Entry(root, width=35)
napis = Label(root, text="nastaveni")
tlacitko = Button(root, text="Generuj!", command=kliknuti, fg="black", bg="cyan")

How do i make so when i generate the password the generated password changes in the entry. Now when you click the button more times the passwords just keep adding to the entry im lost and idk what to do. I am a new programmer. Any help is appreciated.

Answer 1

To ensure that the generated password replaces the existing password in the entry widget each time the button is clicked, you should clear the entry widget and the heslo list before generating a new password. Additionally, you should remove the spaces when joining the list into a string. Try something like this:

from tkinter import *
import string
import random

cisla = string.digits
symboly = string.punctuation
abeceda = string.ascii_letters

root = Tk()
root.title("PASSWORD GENERATOR")

def clear_entry(event):
    event.widget.delete(0, END)

delkahesla = Entry(root, width=35)
delkahesla.insert(0, "How many letters would you like?")
delkahesla.bind("<FocusIn>", clear_entry)

Psymboly = Entry(root, width=35)
Psymboly.insert(0, "How many symbols would you like?")
Psymboly.bind("<FocusIn>", clear_entry)

Pcisla = Entry(root, width=35)
Pcisla.insert(0, "How many numbers would you like?")
Pcisla.bind("<FocusIn>", clear_entry)

def kliknuti():
    heslo = []  # Clear the list each time the button is clicked
    vysledek.delete(0, END)  # Clear the entry widget each time the button is clicked
    try:
        x = int(delkahesla.get())
        y = int(Psymboly.get())
        z = int(Pcisla.get())
    except ValueError:
        vysledek.insert(0, "Please enter valid numbers")
        return

    for i in range(x):
        heslo.append(random.choice(abeceda))
    for i in range(y):
        heslo.append(random.choice(symboly))
    for i in range(z):
        heslo.append(random.choice(cisla))

    random.shuffle(heslo)
    STRheslo = ''.join(heslo)  # Remove spaces when joining the list into a string
    vysledek.insert(0, STRheslo)
    return heslo

vysledek = Entry(root, width=35)
napis = Label(root, text="nastaveni")
tlacitko = Button(root, text="Generuj!", command=kliknuti, fg="black", bg="cyan")

napis.pack()
tlacitko.pack()
delkahesla.pack()
Psymboly.pack()
Pcisla.pack()
vysledek.pack()

root.mainloop()
