Hi everyone, I am trying to make a simple Tic Tac Toe game but I am experiencing an issue. If the player does an illegal move like picking a value that is already picked before I want the program to print "invalid" and let the player choose another number on the table But here's the problem, If a player does an illegal move it prints "invalid" but then lets the player pick 2 values to assign instead of 1, if this doesn't explain the issue here's what happens in the executed: The issue:

Any idea what could be causing the issue? I am a beginner with python so I don't know much, I am using python 3.x
