To find out which names cannot be given to variables in Python, use the command:

import keyword

keyword.kwlist

For Python 3.6 this words are: Читать →

We continue to learn programming. Let’s move on to the study of the third chapter of the book: Michael Dawson “Programming in Python”, 2014 (Michael Dawson “Python Programming for the Absolute Beginner”, 3rd Edition), where we will study if, elif, else conditional statements and while loops and learn how to generate random numbers using a module with the functions random.randint() and random.randrage().

Summary of chapter 3 with examples of programs I wrote:

Random Number Generation in Python

We load the import random module – it generates random numbers based on the built-in formula. To assign a random value to a variable, after calling the module, call one of its functions, for example,

To install Python on your computer, simply search Google for download python and follow the first link to www.python.org/downloads

The easiest way is to click on the bright button with the latest version of Python and then follow the installation process.

In addition to Python itself, you will probably need to install additional programs, which we will discuss next. When installing Python, remember that it is an interpretive programming language. If you write the code in notepad, it won’t work. And the code doesn’t need to be compiled like in C++. To run your code, you use either the built-in interpreter – Python 3.6.exe, or you can activate the interpreter in other text editors or programming environments.

1. Изменение системных переменных среды

Эта настройка позволит запускать программу, написанную на Python, в CMD операционной системы Windows (интерпретатор командной строки). Чтобы это сделать, нажимаем “Пуск” -> Изменение системных переменных среды: Читать →

Once you’ve installed Python on your computer, it’s best to take care of the little nuances that make life easier for programmers. Let’s go through the basic settings of the programming environment and Windows for comfortable work:

1. Changing System Environment Variables

This setting will allow you to run a program written in Python in the CMD of the Windows operating system (command line interpreter). To do this, click “Start” -> Change system environment variables:
