In this recipe, you will learn how to update any information in the database. Changing passwords is a very common requirement in almost all applications. In this recipe, we assume that a database called ECommerce already exists and a table called Users also exists in the ECommerce database. The Users table consists of two columns, EmailAddress and Password. Also, we assume that the Users table contains a few rows in it. The user will be prompted to enter their email address and password in the form. The Users table is searched for the specified email address and password.

Overview of this book
A responsive graphical user interface (GUI) helps you interact with your application, improves user experience, and enhances the efficiency of your applications. With Python, you’ll have access to elaborate GUI frameworks that you can use to build interactive GUIs that stand apart from the rest.
This Learning Path begins by introducing you to Tkinter and PyQt, before guiding you through the application development process. As you expand your GUI by adding more widgets, you'll work with networks, databases, and graphical libraries that enhance its functionality. You'll also learn how to connect to external databases and network resources, test your code, and maximize performance using asynchronous programming. In later chapters, you'll understand how to use the cross-platform features of Tkinter and Qt5 to maintain compatibility across platforms. You’ll be able to mimic the platform-native look and feel, and build executables for deployment across popular computing platforms.
By the end of this Learning Path, you'll have the skills and confidence to design and build high-end GUI applications that can solve real-world problems.
