CodeFactor found an issue: Using the global statement

It's currently on:
source.py\ticTacToe_GC.py:115

Global variables reduce code readability and often cause bugs. Avoid global variable as much as possible.

Example of incorrect code:

WIDTH = 0 # global variable
def area(w):
    global WIDTH # global statement
    WIDTH = w
    return WIDTH * WIDTH

One common solution for this is to create a class and to encapsulate global variables as members of an instantiated object of that class:

class Square:
    def __init__(self, width):
        self.width = width
    def area(self):
        return self.width * self.width

CodeFactor found an issue: Starting a process with a shell: Seems safe, but may be changed in the future, consider rewriting without shell

Example of insecure code:

import os
os.system('/bin/echo suspicious code') \
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function.

Example of secure code:

import subprocess
subprocess.call('/bin/echo suspicious code', shell=False) \
