Password-generator

Pre-requisites

• Tkinter is a standard GUI library and is one of the easiest ways to build a GUI application.
• pyperclip module allows us to copy and paste text to and from the clipboard to your computer
• The random module can generate random numbers
• string module contains a number of functions to process the standard python string.

Install Libraries

• pip install tkinter
• pip install pyperclip
• pip install random
• pip install strings

PS: All these libraries should be available before hand with python distribution, but in case of unavailability use the above command to install

Import Libraries

from tkinter import * import random, string import pyperclip

Initialize Window

root = Tk() root.geometry("400x400") root.resizable(0,0) root.title("DataFlair - PASSWORD GENERATOR")

• Tk() initialized tkinter which means window created
• geometry() set the width and height of the window
• resizable(0,0) set the fixed size of the window
• title() set the title of the window

Label(root, text = 'PASSWORD GENERATOR' , font ='arial 15 bold').pack() Label(root, text ='DataFlair', font ='arial 15 bold').pack(side = BOTTOM)

• Label() widget use to display one or more than one line of text that users can’t able to modify.

• root is the name which we refer to our window

• text which we display on the label

• font in which the text is written

• pack organized widget in block

Select Password Length

pass_label = Label(root, text = 'PASSWORD LENGTH', font = 'arial 10 bold').pack() pass_len = IntVar() length = Spinbox(root, from_ = 8, to_ = 32 , textvariable = pass_len , width = 15).pack()

• pass_len is an integer type variable that stores the length of a password.
• To select the password length we use Spinbox() widget.
• Spinbox() widget is used to select from a fixed number of values. Here the value from 8 to 32

Function to Generate Password

pass_str = StringVar() def Generator(): password = '' for x in range (0,4): Password = random.choice(string.ascii_uppercase) + random.choice(string.ascii_lowercase) + random.choice(string.digits) + random.choice(string.punctuation) for y in range(pass_len.get()- 4): password = password + random.choice(string.ascii_uppercase + string.ascii_lowercase + string.digits + string.punctuation) pass_str.set(password)

• pass_str is a string type variable that stores the generated password
• password = “” is the empty string
• First loop will generate a string of length 4 which is a combination of an uppercase letter, a lowercase letter, digits, and a special symbol and that string will store in password variable.
• The second loop will generate a random string of length entered by the user – 4 and add to the password variable. Here we minus 4 to the length of the user because we already generate the string of length 4.
• We have done this because we want a password which must contain an uppercase, a lowercase, a digit, and a special symbol.

Now the password is set to the pass_str() variable

Button(root, text = "GENERATE PASSWORD" , command = Generator ).pack(pady= 5) Entry(root , textvariable = pass_str).pack()

• Button() widget used to display button on our window
• command is called when the button is click
• Entry() widget used to create an input text field
• textvariable used to retrieve the current text to the entry widget

Function to Copy Password

def Copy_password(): pyperclip.copy(pass_str.get()) Button(root, text = 'COPY TO CLIPBOARD', command = Copy_password).pack(pady=5)

• pyperclip.copy() used to copy the text to clipboard
