Tic Tac Toe except Valueerror help

Python does not like mixture of tabs and spaces. I recommend to check you code for tabs - and replace them with 4 spaces. Adjust your editor to insert 4 spaces when you press tab

Hi, The thing is it is set to 4 spaces and ive checked that theres no more than 4 spaces for the lines however it still says that it is inconsistent. Does anyone know why this could be... thanks.

Oh ok thanks that part is working now, do you or anyone know how to get the "in range0-9" part working? because i dont really know how to make it so that if someone inputs "20" or something it says "Please enter a valid number" or something. THanks.
