Criticize my TIC TAC TOE game

[modeezy23]

Hi! I'm a bit new to python. I've been learning on my own for about 2-3weeks. Here is a typical TIC-TAC-TOE game that I made.
PLEASE LET ME KNOW WHAT I CAN DO TO BETTER IMPROVE MY CODING SKILLS!
IS THIS CONSIDERED GOOD CLEAN CODE?
Thanks in advance for all comments and and advice!

Also, HOW CAN I MAKE LINE 81 SHORTER/LOOK CLEANER?

    player = int(input('\nWhich player are you? (1 or 2): '))

EDIT:
LINE 84: player = 0, num = 0
I forgot to put this statement in. It is needed in order for the code to run properly. Also, I'm sorry for the profanity that shows when you win the game. I forgot to change it before I posted lol.

Not a bad start! A few suggestions:

1. Your update_rows() function doesn't actually do anything. You can remove it and the call on line 101 without affecting the program's behavior.
   
2. Several of your function calls include parameters you aren't using. For example, why pass the player and num values to print_board() when you aren't using them within the function?
   
3. Since turns always alternate in Tic-Tac-Toe, you could build that into the game instead of asking which player the user is. If Player 1 just moved, then it's Player 2's turn, and so on. With your current code, Player 1 can just go three times in a row to win.
   
4. Regarding line 81, there is a much simpler way to tell if the game is a tie. If 9 turns have been completed and there is no winner, it's a tie.
   

You may find other things you'd like to change as well, but those few jumped out at me. Tic-Tac-Toe is a great project to write and rewrite when you are starting out, because there are a ton of different ways to achieve the desired result.

These are all awesome suggestions and advice. Thank you so much for taking the time out of your day to help me out. It means a lot. I’ll definitely try implementing the alternation between players without having to ask. That’ll be fun to figure out. I didn’t realize I didn’t need the update_rows function. I could’ve sworn it made a difference but I’ll definitely try it without. As for line 81, wow, idk how I didn’t think of that. That’s definitely a much simpler way of solving that problem. Again, thanks for your reply! It is very much appreciated and I will definitely take it into consideration to further develop my programming skills!
