Python Login And Register Form With MySQL

How to Create Login and Register Form in Python Tkinter with MySQL Database

In this Python Long Tutorial we will go step by step on How To Design a Login Form And a Register Form, plus how to make a basic main form / dashboard to show to the user after 

successfully logging.

What We Are Gonna Use In This Project:

- Python Programming Language.

- Tkinter for Graphical User interfaces.
- VsCode Editor.
- MySQL Database.
- PhpMyAdmin.

What We Will Do In This Project:

- Design Two Forms For The Login and Signup Using Frames.
- Create Close Button To Close The Form.
- Connect Python To MySQL Database, To Add The Registred User Data In The Signup Form or to Check If The User Exist In The Login Form.
- Browse and Select Image From Your Computer and Set The File Path In a Label .
- Check If The User Leave Some Fields Empty.
- Check If The User Enter Username That Already Exists.
- Check If The User Enter a Wrong Password In The Confirmation Field.
