Trying to add clear() to dungeon game

Question

I'm trying to add a clear() function to my game to stop my console from scrolling. However, what I'm doing doesn't seem to work. Does anyone have any insight into what I'm doing wrong?

import random
import os

CELLS = [(0, 0), (0, 1), (0, 2),
        (1, 0), (1, 1), (1, 2),
        (2, 0), (2, 1), (2, 2)]


def clear():
    if os.name == 'nt':
        os.system('cls')
    else:
        os.system('clear')

def draw_map(player):

    print(' _ _ _')
    tile = '|{}'

    for idx, cell in enumerate(CELLS):
        if idx in [0, 1, 3, 4, 6, 7]:
            if cell == player:
                print(tile.format('X'), end = '')
            else:
                print(tile.format('_'), end = '')
        else:
            if cell == player:
                print(tile.format('X|'))
            else:
                print(tile.format('_|'))
    print('\n\n')

def get_locations():
    monster = random.choice(CELLS)
    door = random.choice(CELLS)
    start = random.choice(CELLS)

    if monster == door or monster == start or door == start:
        return get_locations()
    return monster, door, start

def move_player(player, move):

    x, y = player

    if move == "LEFT":
        y -= 1
    elif move == 'RIGHT':
        y += 1
    elif move == 'UP':
        x -= 1
    elif move == 'DOWN':
        x += 1

    return x, y 

def get_moves(player):
    moves = ['LEFT', 'RIGHT', 'UP', 'DOWN']
    # player = (x, y)

    if player[1] == 0:
        moves.remove('LEFT')
    if player[1] == 2:
        moves.remove('RIGHT')
    if player[0] == 0:
        moves.remove('UP')
    if player[0] == 2:
        moves.remove('DOWN')

    return moves

# game loop
clear()

monster, door, player = get_locations()
print("Welcome to the dungeon")

while True:
    moves = get_moves(player)
    draw_map(player)

    print("You're in room {}".format(player))


    print("You can move {}".format(moves))
    print("Enter QUIT to quit")

    move = input("> ")
    move = move.upper()

    if move == 'QUIT':
        break
    if move in moves:
        player = move_player(player, move)
    if move not in moves:
        print("That's not a vaild move! Try again")
    else:
        print("** Walls are hard, stop walking into them! **")
        continue

    if player == door:
        print("You escaped!")
        break
    elif player == monster:
        print("You were eaten by the monster!")
        break

You can put a clear() as the last statement of the while code block. That way it runs just before each iteration restarts.

There seems to be a bug in your if move in moves code.

    if move in moves:
        # this runs if move in moves
        player = move_player(player, move)
    if move not in moves:
        # this runs if move is Not in moves
        print("That's not a vaild move! Try again")
    else:
        # this runs if move in moves (seems not what you want)
        print("** Walls are hard, stop walking into them! **")
        continue  # Why is this continue here?

This could be simplified to:

    if move in moves:
        # this runs if move in moves
        player = move_player(player, move)
    else:
        # this runs if move is Not in moves
        print("That's not a vaild move! Try again")
