Tic Tac Toe Python 3: The Standard Tic-Tac-Toe Game in Python 3

I just finished Tic tac toe game as my first python project. This is a very simple classic game, for beginners in programming tic-tac-toe game is the best choice. I am using Jupyter notebook, you can use any python ide like Pycharm, Spyder etc.

Scenario of tic-tac-toe game:

Your task is to write a simple program which pretends to play Tic-tac-toe game with the user. To make it easier for you. We have decided to simplify the game. Here are our assumptions.

• the computer should play a game using 'X'
• the user should play a game using 'O'
• the first move belongs to the computer, it always 'X' in the middle of the board. 

• all squares are numbered row by row, start with '1'.
• the user move is to enter the number of the square they choose, the number must be valid, that is it must be an integer, it must be greater than  0 and less than 10, and it cannot point to a field which is already occupied.
• the program checks the game is over, there are four possibilities- the game should continue, the game should tie, computer's win and you win.
• don't implement any form of artificial intelligence's, a random field is chosen by a computer this is enough for the game.

Requirements to build tic-tac-toe game:

1. Better knowledge about if-elif-else, for-while loop, tuple, list, function.
2. Draw a random function you can use randrange() 

from random import randrange

for i in range(10): print(randrange(8))  

1. Display Board function of tic-tac-toe game:

The function accepts one parameter containing the board's current status and prints it out to the console.

2.Enter a move:

The function accepts the board current status, asks the user about their move,  checks the input and updates the board according to the user's decision.

3. Make a list of the free field:

The function browses the board, builds a list of all the free squares and the list consists of tuples, while each tuple is a pair of row-column numbers.

4.Victory for :

The function analyzes the board status to check if the player using 'O's or 'X's has won the game.

5.Draw move:

The function draws the computer's move and updates the board.

6.Main program:

And then combine this function so, the main program:
