This book will talk about how to write programs in a programming language called Python (correctly read as Python, but usually the name of the language is read as Python, which is also quite acceptable). Thus, we will solve two problems, one of which is a priority, and the second, although auxiliary, is quite important. Our main task, of course, is to study the syntax of the Python programming language. At the same time, we will master programming as such, explicitly or implicitly taking into account that the corresponding algorithms are supposed to be implemented in Python. Most book authors in their works consider the theoretical foundations of the language and focus on the basic syntax of the language, without considering the practical side of its application. The same book tries to fill the lack of practical material; it contains many examples with comments that you can use as the basis for your software solutions and learning Python. The material in the book is presented sequentially and is accompanied by a large number of illustrative examples, diverse practical problems and a detailed analysis of their solutions.
