hi where to download the software to program this.

thank you

For gaming in Python, According to my view, PyCharm is comfortable.
Here is the link to download it.

Hey, how can I make the program print an error message and then ask for an input again if the user inputs a letter or a character that isn't a number?

osm logic.

Nice program!

amazing content to learn from for beginners like me.

its showing error in move = int(input())
when ever we put any char value its shows error

Can you please help me with my code for tic-tac-toe (2 player). The output gets printed three times.
Here is the link to the code.

@Avishekp6460 why are you inputting char values? if you wish to fix that (even there's no reason to), just implement a try-except statement.

well this was useful!

Hey can someone give me a logic walkthrough? or some resources that can be refered to?

Very helpful, thanks

can you use in this program that works restart the program use the if else condition or Y/N

Thanks 😎✌

you know what, you can beat this AI with 4, 2, 5, 8. again and again
