List appending not like they should

Well I have been working on this game for my "AI" for a few hours and it is just a list-text based game, for some reason tho, the lists are not like I would say they should.

import random

sizeX = 3
sizeY = 4
won = 0
coordX = random.randint(0, 2)
coordY = random.randint(0, 3)
displayLayer = []

def move():
    global coordX, coordY, won
    print("Where do u wanna move [W, A, S, D]")
    userInput = input()
    if userInput == 'w' or 'W':
        if coordY == 0:
            won = 1
        else:
            coordY = coordY + 1
    if userInput == 'a' or 'A':
        if coordX == 0:
            pass
        else:
            coordX = coordX - 1
    if userInput == 's' or 'S':
        if coordY == sizeY - 1:
            pass
        else:
            coordY = coordY - 1
    if userInput == 'd' or 'D':
        if coordX == sizeX - 1:
            pass
        else:
            coordX = coordX + 1

def updateVisuals(y):
    global coordX, coordY
    if y == coordY + 1:
        for i in range(coordX):
            displayLayer.append(0)
        displayLayer.append(1)
        for i in range(sizeX - coordX - 1):
            displayLayer.append(0)
    else:
        for i in range(sizeX):
            displayLayer.append(0)

def showLists():
    for i in range(sizeY):
        displayLayer.clear()
        updateVisuals(i)
        print(displayLayer)

showLists()
move()
showLists()

sometimes the "player" (1) is just out of "map" and it doesn't move, sometimes I do 'd' and I move up, I would love help...
