Tools of the Google Colaboratory cloud environment for programming training and the preparation for the unified state exam in informatics

One of the cloud technologies that can be used to teach programming based on the Python programming language is the Google Colaboratory cloud service. This service can be used by teachers both when teaching certain themes of the section "Algorithms and programming" as part of a school informatics course, and when preparing students for the tasks in programming of the Unified State Exam in informatics. The article discusses the possibilities of the Google Colaboratory cloud service for creating interactive notebooks using the example of an interactive notebook and practical work on the theme "A precondition loop", as well as interactive notebooks "Task No. 24 of the Unified State Exam in informatics" for students and teachers. The applicability of these notebooks for programming training based on the Python language as part of a school informatics course and for preparing students for tasks in programming of the Unified State Exam in informatics is substantiated.
