 Problem with coding for movement keys
#1
I am following a youtube tutorial on how to make a multiplayer game in python: https://www.youtube.com/watch?v=_fx7FQ3SP0U. I am using the online python editor, compiler, and interpreter https://repl.it/languages/python3. Whenever I run the code, I get this error: Python 3.6.1 (default, Dec 2015, 13:05:11)
[GCC 4.8.2] on linux
File "main.py", line 26
if keys[pygame.K_LEFT]
^
SyntaxError: invalid syntax


This is my code:
import pygame

width = 500
height = 500
win = pygame.display.set_mode((width, height))
pygame.display.set_caption("Client")

clientNumber = 0

class Player():
    def __init__(self, x, y, width, height, color):
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.color = color
        self.rect = (x, y, width, height)
        self.vel = 3

    def draw(self, win):
      pygame.draw.rect(win, self.color, self.rect)

    def move(self):
        keys = pygame.key.get_pressed()

        if keys[pygame.K_LEFT]
            self.x -= self.vel

        if keys[pygame.K_RIGHT]
            self.x += self.vel

        if keys[pygame.K_UP]
            self.y -+ self.vel

        if keys[pygame.K_DOWN]
            self.y += self.vel

        self.rect = (self.x, self.y, self.width, self.height)    



def redrawWindow(win, player):
    win.fill(255, 255, 255)
    player.draw(win)
    pygame.display.update()


def main():
    run = True
    p = Player(50, 50, 100, 100, (0, 255, 0))
    pygame.time.clock()
    
    while run:
      clock.tick(60)
        for event in pygame.event.get():
          if event.type == pygame.QUIT:
            run = False
            pygame.quit()

        p.move()
        redrawWindow(win, p)

main()
Can anybody tell me what's wrong with it?
I'm using Ubuntu, not Windows. I don't know if that helps.

I found a pygame tutorial on repl.it. It said to make an account, click new repl, and choose pygame from language list: I pasted in the same code I had before: this is what I got:

Python 3.6.7

You need colons (:) at the end of your if statements. You need a colon before any indented block of code in Python.

I added pygame.init() before width = 500 and after import pygame, because repl.it said to. but it kept saying this:

Python 3.6.7
 bash -c polygott-x11-vnc q && DISPLAY=:0 run-project
nohup: redirecting stderr to stdout

PLease help - I'm super confused.

It still didn't work, I'll just take more courses until I figure this out.

That's not an error. It's just a message letting you know what it's doing.

It seems like the issue is with trying to start python. Is there a reason you can't install it on your computer?
