The code is isn't running, it is a Pygame code for a race game, everytime I try to run it, it says ImportError: No module named Pygame. I don't have any idea if this code has any other problems, so as far as I know it is only the Import Error. Can you help me solve the Import Error and any other problems that occur?

pygame.image.load() loads an image and returns the a Surface object. Your surface goes to nowhere:
def carImg():
pygame.image.load('racecar.png')
carImg has to be a variable rather then a function. Assign the Surface object to carImg:
carImg = pygame.image.load('racecar.png')

Here's a simple pygame code where I inserted a screen, a pink rectangle and tried moving it.
The rectangle in the pygame window isn't moving.
Which means the code inside '**' isn't working.
How do I solve that?
import pygame, sys
pygame.init()
width = 800
height = 600
pink = (244,133,227)
player_pos = [400, 300]
player_size = 50
screen = pygame.display.set_mode((width,height))
game_over = False
while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
** if event.type == pygame.KEYDOWN:
x = player_pos[0]
y = player_pos[1]
if event.type == pygame.K_LEFT:
x -= player_size
elif event.type == pygame.K_RIGHT:
x += player_size
player_pos = [x, y]
screen.fill((0,0,0)) **
pygame.draw.rect(screen, pink, (player_pos[0], player_pos[1], player_size, player_size))
pygame.display.update()
The key is stored in the key attribute, rather then the type attribute. See pygame.event:
if event.type== pygame.K_LEFT:
if event.key == pygame.K_LEFT:
See the example:
import pygame, sys
pygame.init()
width = 800
height = 600
pink = (244,133,227)
player_pos = [400, 300]
player_size = 50
screen = pygame.display.set_mode((width,height))
game_over = False
while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
if event.type == pygame.KEYDOWN:
x = player_pos[0]
y = player_pos[1]
if event.key == pygame.K_LEFT:
x -= player_size
elif event.key == pygame.K_RIGHT:
x += player_size
player_pos = [x, y]
screen.fill((0,0,0))
pygame.draw.rect(screen, pink, (player_pos[0], player_pos[1], player_size, player_size))
pygame.display.update()
I'm here to ask what is the problem with my code? I'm making a game engine, and I thought the easiest way to sort player types would be putting them into a different script and using them there. However, I am having a slight issue doing that, and have no clue how to fix it.
Here is the error I'm getting:

P.S: If there is an easier way to do this, please tell me!

Your error message is saying that the function topDownPlayerControls is not defined. This is because you are trying to call it as a free function. However, this function is defined within the playerMovement class. So, you would first need to create a playerMovement object, and then call the topDownPlayerControls function on that object. It would look something like this:
player = playerMovement()
player.topDownPlayerControls()
It looks like you will have a number of other fails after that, but I'll leave that as an exercise :)
I'm just messing around with Pygame and I can't see what I'm doing incorrectly to make the red circle move with the arrow keys. I can't tell if it's in my main loop. I also haven't been able to find very many tutorials on sprite or looping animations with Pygame. If I for example wanted to make a square oscillate for example like a moving platform how would I do that?
import pygame

### main loop

while dead != True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
dead = True
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
player_x = -1
elif event.key == pygame.K_RIGHT:
player_x = +1
if event.key == pygame.K_UP:
player_y = +1
elif event.key == pygame.K_DOWN:

if event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or pygame.K_RIGHT:
player_x = 0
if event.key == pygame.K_UP or pygame.K_DOWN:
player_y = 0
game_screen.fill(black)
player()
pygame.display.update()
x -= player_x
y -= player_y
pygame.quit()
quit()
Your indendation is all messed up.
Your code won't do anything unless the event is QUIT... which then makes it quit.
Your boolean logic is wrong.
This is not proper syntax event.key == pygame.K_UP or pygame.K_DOWN. The order of precedence here is as follows (event.key == pygame.K_UP) or (K_DOWN). Since K_DOWN is truthy, it is always true and thus this entire statement is always true.
I think you mean: event.key == pygame.K_UP or event.key == pygame.K_DOWN
Lastly, it wont' keep moving as you say you want.
It will only move when there is an event in the queue. You can make it keep moving by generating events. Perhaps with an event timer.
Here is a fixed version, hope this helps:

player_x = 0

I started watching a youtube video series on learning pygame by sentdex.
I have been following all his steps and i got to the point where i had a car(the image) and it was on a white screen. But, when i put in the functions to be able to move the car. Next time i ran it I could not see my car. I noticed that I could see it for a split second when i closed the screen.I have tried searching this question every way that i could think of. It is probably a small stupid mistake on my part. Thank you in advance

Your indentation is messed up. Everything from for event in pygame.event.get(): to clock.tick(60) should be indented to show that it fits inside the while not crashed: loop. Also, crashed = True should be indented to show that it is inside the if event.type == pygame.QUIT: statement. In addition, the pygame.KEYDOWN and pygame.KEYUP comparisons should be inside your for event in pygame.event.get(): loop. Finally, you can improve speed by changing some of the ifs to elifs. This is the corrected version of the last section of your code:
while not crashed:
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x_change = -5
elif event.key == pygame.K_RIGHT:
x_change = 5
elif event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
x_change = 0
x += x_change
gameDisplay.fill(white)
car(x, y)
pygame.display.update()
clock.tick(60)
pygame.quit()

I am using python 2.7 an tried to make a simple game using the pygame module. In the program it makes a rectangle, and what I am having trouble doing is getting it to move upon keys being pressed. I believe the problem is with the 'player.move' part in my code, but the documentation was poor for it on pygames website. Any help is appreciated.

Find tutorial (ie, Program Arcade Games With Python And Pygame) because you have many things to change.
PyGame is low-level library and you have to do everything on your own. In while loop you have to clear screen or draw background and draw player - again and again.
Here your code after modifications.
You have to learn pygame.Rect, pygame.Surface, (pygame.Sprite), events, etc.
