How to move a Rect in pygame (using Rect.x, Rect.y)?

Question

I am pretty new to pygame and I want to make a simple platformer script that will let me move my player across a level. When I run my code my player and level both show up on my screen but my player does not fall due to the gravity I implemented and also does not move when using keyboard input. Normally for a problem like this, I would go through the code shown on the syntax error but I am not getting a syntax error so I was wondering if maybe I had looked upon the wrong documentation or built-in functions when I was creating this.

Code:

import pygame
import math
from pygame import mixer
from pygame.constants import K_LEFT, K_RIGHT, K_UP, KEYDOWN
from pygame.locals import *
from pygame.sprite import LayeredUpdates

pygame.init()

screen = pygame.display.set_mode((640, 360))
running = True

# player
#global playerRect
global levelRect
global gravity
global jump_force
global acceleration
global ressistance
global falling
global last_value
global playerX_change
global playerY_change

gravity = -1
jump_force = 14
acceleration = 2
ressistance = 0.85
speedy = 0
speedx = 0
falling = 0
last_value = 0
playerX_change = 0
playerY_change = 0

# creates the player func
def player(x, y):
    global playerRect
    playerRect = pygame.draw.rect(screen, (255, 255, 255), [x, y, 32, 32])

# level
def level(x, y):
    global levelRect
    levelRect = pygame.draw.rect(screen, (0, 0, 255), [x, y, 640, 40])
              
              
while running:
    
    screen.fill((0, 0, 0))
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

        if event.type == KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False
    
            # player movement
            if event.key == K_UP:
                if falling < 3:
                    speedy = 12
            if event.key == K_LEFT:
                speedx += 0 - acceleration
            if event.key == K_RIGHT:
                speedx += acceleration
            speedx = speedx * ressistance
            speedy += gravity
            steps = abs(speedx) + abs(speedy)
            steps = int(steps)
            
            falling += 1
            last_value = playerRect.x
            playerRect.x += speedx / steps
            collided = playerRect.colliderect(levelRect)
            if collided:
                playerRect.x = last_value
                speedx = 0
            last_value = playerRect.y
            playerRect.y += speedy / steps
            collided = playerRect.colliderect(levelRect)
            if collided:
                playerRect.y = last_value
                if speedy < 0:
                    falling = 0
                
                
                
    player(10, 275)
    level(0, 325)
    
    pygame.display.update()
