Python GUI Programming Cookbook, Second Edition - Second Edition

Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Preface

Using the SQL UPDATE command


This recipe will use the code from the previous recipe, Using the SQL INSERT command, explain it in more detail, and then extend the code to update our data.

In order to update the data that we previously inserted into our MySQL database tables, we use the SQL UPDATE command.

Getting ready

This recipe builds on the previous recipe, Using the SQL INSERT command, so read and study the previous recipe in order to follow the coding in this recipe, where we modify the existing data.

How to do it…

First, we will display the data to be modified by running the following Python to MySQL command:

import MySQLdb as mysql 
import Ch07_Code.GuiDBConfig as guiConf 

class MySQL(): 
    # class variable 
    GUIDB  = 'GuiDB' 
    #------------------------------------------------------ 
    def showData(self): 
        # connect to MySQL 
        conn, cursor = self.connect()    

        self.useGuiDB(cursor)       

        # execute command 
        cursor.execute("SELECT * FROM...
