Password Generator (GUI)

Google gives you suggestions when you create your new passwords Right!

In the same way, python makes it too easy for you to create your own password generator rather than using other tools like google.

We are providing you the full source code with the explanation at every line which we are sure will help you.

# importing the tkinter module
from tkinter import *

# importing the pyperclip module to use it to copy our generated 
# password to clipboard
import pyperclip

# random module will be used in generating the random password
import random

# initializing the tkinter
root = Tk()

# setting the width and height of the gui
root.geometry("400x400")    # x is small case here

# declaring a variable of string type and this variable will be 
# used to store the password generated
passstr = StringVar()

# declaring a variable of integer type which will be used to 
# store the length of the password entered by the user
passlen = IntVar()

# setting the length of the password to zero initially
passlen.set(0)


# function to generate the password
def generate():
    # storing the keys in a list which will be used to generate 
    # the password 
    pass1 = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j',
            'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't',

            '*', '(', ')']

    # declaring the empty string
    password = ""

    # loop to generate the random password of the length entered           
    # by the user
    for x in range(passlen.get()):
        password = password + random.choice(pass1)

    # setting the password to the entry widget
    passstr.set(password)

# function to copy the password to the clipboard
def copytoclipboard():
    random_password = passstr.get()
    pyperclip.copy(random_password)

# Creating a text label widget
Label(root, text="Password Generator Application", font="calibri 20 bold").pack()

# Creating a text label widget
Label(root, text="Enter password length").pack(pady=3)

# Creating a entry widget to take password length entered by the 
# user
Entry(root, textvariable=passlen).pack(pady=3)

# button to call the generate function
Button(root, text="Generate Password", command=generate).pack(pady=7)

# entry widget to show the generated password
Entry(root, textvariable=passstr).pack(pady=3)

# button to call the copytoclipboard function
Button(root, text="Copy to clipboard", command=copytoclipboard).pack()

# mainloop() is an infinite loop used to run the application when 
# it's in ready state 
root.mainloop()
