I made this code to make a tic-tac-toe game without a GUI in PYTHON

Question

I made this code on tic-tac-toe in python and after iterating it works fine but in between the computer stops giving input. My code involves a user vs computer game. Please help me I know my code doesn't contain comments but I hope you will understand and I am a beginner so please help me!!!

In this code, the computer first asks you a choice to take O or X and then does a toss in which you enter 1 or 0 and compares it to a variable that has a random value between 1 and 0. Then according to toss either the user plays first or the computer.

For computer I used the randint() function so that it chooses the row and column in which it places X or O. In every iteration the code checks whether the random row or column computer gets does not matches with the already filled ones. So this is all about this code!!

import random
row1=None
column1=None
row2 = None
column2 = None
data1=[]
data2=[]
data3=[]
data4=[]
count=0
count2=0
print("Welcome to TIC-TAC-TOE!!")
tic=input("Enter O or X as your choice --> ")
if tic=='O':
    tac='X'
else:
    tac='O'
block=[[' ',' ',' '],[' ',' ',' '],[' ',' ',' ']]
i=0
choice=int(input("Enter 1 for Head and 0 for Tail --> "))
x=random.randint(0,1)
if choice==x:
    print("You won the toss you get the first chance : ")
    print("## Enter the row and column you want to put your choice in ##")
    row1=int(input("Row --> "))
    data1.append(row1)
    column1=int(input("Column --> "))
    data2.append(column1)
    block[row1-1][column1-1]=tic
    print(block[0][0],"|",block[0][1],"|",block[0][2])
    print(block[1][0],"|",block[1][1],"|",block[1][2])
    print(block[2][0],"|",block[2][1],"|",block[2][2])
    while True:
        i+=1
        if block[0][0]==block[0][1] and block[0][1]==block[0][2] and block[0][0]!=' ':
            if block[0][0]==tic:
                print("You Win!!")

play_game()

Answer 2

I changed the code a bit and removed the while loops instead i replaced it with another while loop in which it checks whether the place with that row and column has white space or not if not then the column keeps on changing randomly until a place comes where there is a white space.Now for the row i simply checked whether the whole row is occupied or not if it is then the row keeps on changing randomly.This whole logic was changed for just the computer's turn.and guess what i reduced the code from 300 lines to 188 lines like 50%

Also changed the logic for draw it was rekt basically it just now checks whether all the places are not white spaces if yes then it gives draw

The Improved Code
