Validation checking

[Help_me_Please]

I have emended the code as appropriate but I'm still stuck in the loop:

turn = 0
game_over = False

def board_create(column, row):
    board = [[' '] * column for row in range(row)]
    return board

def is_valid_location(column_choice, invalid):
    if (column-1) < column_choice < (column+1):
        return False, column_choice, invalid
    else:
        return True, column_choice, invalid
    
row = int(input("How many rows: "))
column = int(input("How many columns: "))
board = board_create(column, row)

while not game_over:
    if turn == 0:
        invalid = True
        while invalid == True:
            column = str(column)
            column_choice = int(input("Player 1 make your selection (1-"+column+"):"))
            column = int(column)
            invalid = is_valid_location(column_choice, invalid)
    else:
        while invalid == True:
            column = str(column)
            column_choice = int(input("Player 2 make your selection (1-"+column+"):"))
            column = int(column)
            invalid = is_valid_location(column_choice, invalid)
    turn = turn + 1
    turn = turn % 2
