Pygame arrow keys not working

Question

I'm trying to follow this tutorial: https://www.youtube.com/watch?v=UdsNBIzsmlI

I've copied the code (I think exactly) but when I run it in Terminal, any key events just go to the Terminal. Nothing happens in the pygame window and when I close it, all of the key events attempt to execute in the Terminal. Am I missing something?

FWIW, when I added print(keys) the value that appeared in the list when I hit a key was not the value given for that key by pygame.K_LEFT (or whatever key). It was the value the interpreter shows for that key ([(C or whatever).

My stuff:

• Python 3.6.5
• Latest version of pyGame installed with Pip yesterday
• Mac 10.9

Here's the code I have:

import pygame

pygame.init()

win = pygame.display.set_mode((500,500))

pygame.display.set_caption("Learning pyGame")

x = 50
y = 425

width = 40
height = 60
vel = 5
isJump = False
jumpCount = 10

clock = pygame.time.Clock()
run = True
while run:
    clock.tick(60)

    ev = pygame.event.poll()
    if ev.type == pygame.QUIT:
        run = False

    keys = pygame.key.get_pressed()

    if keys[pygame.K_LEFT] and x > vel:
        x -= vel
    if keys[pygame.K_RIGHT] and x < 500 - width - vel:
        x += vel

    if not(isJump):
        if keys[pygame.K_UP] and y > vel:
            y -= vel
        if keys[pygame.K_DOWN] and y < 500 - height - vel:
            y += vel
    else:
        if jumpCount >= -10:
            neg = 1
            if jumpCount < 0:
                neg = -1
            y -= (jumpCount ** 2) * 0.5 * neg
            jumpCount -= 1
        else:
            isJump = False
            jumpCount = 10

    win.fill((0, 0, 0))
    pygame.draw.rect(win, (255, 0, 0), (x, y, width, height))
    pygame.display.update()

pygame.quit()
