This course introduces students to the basics of modern programming in Python and to the procedures for creating high-quality, clear, and maintainable code. Students will learn how to work with the development environment, versioning, and basic tools for code analysis. The course covers key elements of the language, such as data structures, functions, exceptions, generators, iterators, and the principles of object-oriented programming. It also includes the basics of graphical user interfaces, testing, program debugging, parallel processing, and application performance optimization. The course concludes with the practical use of Python for communication via REST API and gRPC and a summary of the knowledge acquired. The aim is to prepare students to independently create robust and efficient applications in Python.
