Welcome folks today in this blog post we will be building a complex password generator in python tkinter using random and pyperclip Library. All the full source code of the application is shown below.

Get Started

In order to get started we need to install the tkinter and random and pyperclip library by issuing the npm command

npm i random

npm i tkinter

npm i pyperclip

After installing all the libraries we need to make an  app.py file and copy paste the following code

app.py

import random
import pyperclip
import tkinter as tk
def copyclip():
    passwordcopy=result["text"]
    pyperclip.copy(passwordcopy)
def generate1():  
    try:
        n=int(number.get())
        password=""
        listpass=['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h','i', 'j', 'k', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z','A', 'B', 'C', 'D', 'E', 'F', 'G', 'H','I', 'J', 'K', 'M', 'N', 'O', 'p', 'Q','R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y','Z']
        for i in range(0,n):
            password+=random.choice(listpass)
        result["text"]=password
    except:
        result["text"]="Invalid Number"
def generate2():
    try:
        n=int(number.get())
        password=""
        listpass=['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h','i', 'j', 'k', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z','A', 'B', 'C', 'D', 'E', 'F', 'G', 'H','I', 'J', 'K', 'M', 'N', 'O', 'p', 'Q','R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y','Z','0','1','2','3','4', '5', '6', '7', '8', '9']
        for i in range(0,n):
            password+=random.choice(listpass)
        result["text"]=password
    except:
        result["text"]="Invalid Number"
def generate3():
    try:
        n=int(number.get())
        password=""
        listpass=['0','1','2','3','4', '5', '6', '7', '8', '9']
        for i in range(0,n):
            password+=random.choice(listpass)
        result["text"]=password
    except:
        result["text"]="Invalid Number"
def generate4():
    try:
        n=int(number.get())
        password=""
        listpass=['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h','i', 'j', 'k', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z','A', 'B', 'C', 'D', 'E', 'F', 'G', 'H','I', 'J', 'K', 'M', 'N', 'O', 'p', 'Q','R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y','Z','0','1','2','3','4', '5', '6', '7', '8', '9','@', '#', '$', '%', '=', ':', '?', '.', '/', '|', '~', '>','*', '(', ')']
        for i in range(0,n):
            password+=random.choice(listpass)
        result["text"]=password
    except:
        result["text"]="Invalid Number"
window=tk.Tk()
window.geometry("500x260") #width x height
window.grid_columnconfigure((0,1), weight=1)
window.title("Password Generator")
numberlbl=tk.Label(
    text="Enter Number of Digits - ",
    width=20,
    font=('Helvetica', 12, 'bold')
    )
number=tk.Entry(
    width=30,)
option1=tk.Button(
    text="1.Characters only",
    width=50,
    height=1,
    command=generate1,
    font=('Helvetica', 10, 'bold')
    )
option2=tk.Button(
    text="2.Characters and numbers only",
    width=50,
    height=1,
    command=generate2,
    font=('Helvetica', 10, 'bold')
    )
option3=tk.Button(
    text="3.Numbers only",
    width=50,
    height=1,
    command=generate3,
    font=('Helvetica', 10, 'bold')
    )
option4=tk.Button(
    text="4.Characters numbers and symbols",
    width=50,
    height=1,
    command=generate4,
    font=('Helvetica', 10, 'bold')
    )
texts=tk.Label(
    text="Generated Password is - ",
    height=1,
    width=20,
    font=('Helvetica', 12, 'bold')
    )
result=tk.Label(
    height=3,
    width=20,
    bg="black",
    fg="white",
    font=('Times New Roman', 12, 'italic')
    )
about=tk.Label(
    text='''
    This is a password generator created by Darsh Jain.

    ''',
    fg="grey",
    height=2,)
copy=tk.Button(
    text="Copy To Clipboard",
    width=20,
    command=copyclip,)
numberlbl.grid(row=1,column=0)
number.grid(row=1,column=1)
option1.grid(row=2,columnspan=2)
option2.grid(row=3,columnspan=2)
option3.grid(row=4,columnspan=2)
option4.grid(row=5,columnspan=2)
texts.grid(row=6,column=0)
result.grid(row=6,column=1)
copy.grid(row=7,column=1)
about.grid(row=9,columnspan=2)
window.mainloop()

Now if you execute this python script you will see the following result

Now in the above password generator you will be able to write the number of characters you want to generate the password after that you can choose what you want inside the password you can select and you can also copy to clipboard the result password.
