Day 29

Standard Dialogs

• Standard Dialogs are used to get input from the user.
• They are similar to alerts and prompts in JavaScript.
• The tkinter module has a number of standard dialogs that you can use.
• These are pop-up windows that appear on top of the current window, and are used to get input from the user or to display information.
• The tkinter module has the following standard dialogs −
  • tkinter.messagebox
  • tkinter.filedialog
  • tkinter.colorchooser
  • tkinter.font
  • tkinter.scrolledtext
  • tkinter.simpledialog

Password Generator

• The password generator is a simple program that generates a random password.
• The user inputs a website name, an email/username, and a password.
• The user can also generate a random password which is copied to the clipboard.
• When the user clicks the Add button, the website name, email/username, and password are added to a text file which is stored in the same directory as the program.
