got pygame working now just need to fix this code

okay i managed to get pygame and pycharm working again turns out pygame wasnt in the Interpriter settings even tho it sometimes worked? and that the file kept being changed over to main.py while i was looking at my file got the files back but if anyone know the issues im having that would be great.

please be gentle i only started 2 days ago

import pygame

# pygame setup stuff
pygame.init()
screen = pygame.display.set_mode((800, 600))
pygame.display.set_caption('my First Game')
clock = pygame.time.Clock()
running = True


dt = 0
player_pos = pygame.Vector2(screen.get_width() / 2, screen.get_height() / 2)


while running:
    # poll for events
    # pygame.QUIT () event means the user clicked the X
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # pick the screen color
    screen.fill("purple")

    # RENDER MY GAME HERE
    pygame.draw.circle(screen, "red", player_pos, 40)

    # Move the circle
    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP]:
        player_pos.y -= 300 * dt

    keys = pygame.key.get_pressed()
    if keys[pygame.K_DOWN]:
        player_pos.y += 300 * dt

    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player_pos.x -= 300 * dt

    keys = pygame.key.get_pressed()
    if keys[pygame.K_RIGHT]:
        player_pos.x += 300 * dt


    # use the mouse!!
    if event.type == pygame.MOUSEBUTTONDOWN: (left is were event is getting underlined)
        pos = pygame.mouse.get_pos()
        #move the circle
        player_pos.x = pos[0]
        player_pos.y = pos[1]

    if event.type == pygame.MOUSEBUTTONDOWN:
        pos = pygame.mouse.get_pos()
        print(pos)

    # Flip the display to output my work to the screen
    pygame.display.flip()

    # Set the clock stuff / delta time in seconds since the last frame
    # Used for framerate independent physics
    dt = clock.tick(60) / 1000

pygame.quit()
