If you want to program with Python, you’ve come to the right place! Take your first steps with this Python crash course that teaches you to use core language elements, from variables to branches to loops. Follow expert guidance to work with data types, functions, and modules—and learn how to manage errors and exceptions along the way. Apply Python programming to develop databases, graphical user interfaces, widgets, and more. Practice your skills with example exercises, and start developing your own applications with Python today!
In this book, you’ll learn аbout:
a. Language Basics
Learn the Python fundamentals, from initial installation to running your first program. Master core concepts including variables, branching, loops, functions, and modules; then work with data types such as integers, strings, and tuples.
b. Python in Practice
Apply Python programming in key development scenarios. Use Python for object-oriented programming, create and identify threads, manage files and directories, develop databases with SQLite and MySQL, and more.
c. Example Exercises
Get hands-on experience with practical programming exercises. Follow along with a game development example as you move from chapter to chapter. You’ll be ready to create your own applications with Python in no time!
Highlights include:
1) Installation
2) Python language basics
3) Object-oriented programming
4) Error handling
5) Data types
6) Multithreading
7) File processing
8) Databases
10) GUI programming

Python is an extremely easy programming language to learn and is ideal for getting started in the world of programming. Despite its simplicity, this language also offers the possibility of writing complex programs for a wide range of applications. Python is particularly suitable for the rapid development of extensive applications and combines the following advantages for this purpose:
• A simple, unambiguous syntax
Python is an ideal programming language for anyone starting out in programming. It is limited to simple, clear statements and often to a single possible solution. This language can be quickly learned and memorized and becomes familiar during the development of programs.
• Clear structures
Python requires you to write in an easily readable structure. The arrangement of program lines also determines the logical structure of the program.
• Reuse of code
Modularization, that is, breaking down a problem into sub-problems and then combining the partial solutions into an overall solution, is quite easy in Python. The existing partial solutions can easily be used for further tasks, so you’ll soon have an extensive pool of modules at your disposal.
• Improved troubleshooting
Python versions 3.10 to 3.12 include many improvements to error messages. Error messages are now more informative and accurate and therefore help better with troubleshooting. Suitable suggestions for rectifying an error are often already made.
• Object-oriented processing
In Python, all data is stored as objects. This approach leads to a uniform treatment of objects of different types. The physical storage of Python objects is automatic. During development, you don’t need to worry about reserving and releasing suitable memory areas.
• Interpreter/compiler
Python programs are interpreted directly. They don’t have to be compiled and bound first, which enables frequent, rapid switching between the coding and test phases.
• Independence from the operating system
Both programs that are operated from the command line, and programs with graphical user interfaces (GUIs) can be used on different operating systems (Windows, Linux, macOS) without new development and adaptation.
• Expansion possibilities
Numerous libraries are either already integrated or can be integrated very easily. The libraries contain useful, specialized functions from many areas.
