We continue to learn the Python programming language Python. Let’s move on to chapter 6 “Functions. Tic-Tac-Toe Game” from the book: Michael Dawson “Python Programming”, 2014 (Michael Dawson “Python Programming for the Absolute Beginner”, 3rd Edition) to create our own functions and work with global variables .

How to create a function?

General view of a function in Python: function_name()

To create your own function, you need to declare it.

General form of a function declaration

def function_name(parameter1, parameter2...):

    '''Document string'''

  Function expression block

We continue to learn the Python programming language Python. We turn to the study of chapter 5 of the book: Michael Dawson “Programming in Python”, 2014 (Michael Dawson “Python Programming for the Absolute Beginner”, 3rd Edition), where we will master lists, list methods and dictionaries.

Lists in Python

Lists are similar to tuples, which we studied in the last chapter. It’s important to remember that, unlike tuples, lists can change. The general principles for working with tuples apply to lists.

Основные условия в Python:

• < (одно меньше другого)
• > (одно больше другого)
• <= (одно меньше или равно другому)
• >= (одно больше или равно другому)
• != (одно не равно другому)
• == (одно равно другому)

Примеры использования условий:

print(5 > 4)

True #результат

print(‘cat’==’dog’)

False #результат Читать →

Loops in Python are pieces of code that repeat multiple times.

range(start,stop,step) – this is how the forLoop loop looks in general, where start and stop describe the actual beginning and end of the loop, including the start point, but not including the end point; step – the step with which the computer moves from the start point to the end point (another step is called increment).

Example:

range(1,10,2) means 1, 3, 5, 7, 9

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,
