adding an image with pygame

I am just programming a small game with python and the pygame library.
The game's idea is to have a small charakter running around the floor avoiding to crash into a falling rectunglar.
It all works out from the game logic side.
But I still have problem when the game starts:
As I invert the player horizontally, depending on which direction it is heading to, I had to assign 2 images depending on the key pressed. Now, everytime I start the game and no key is pressed yet, there is only a "hidden/transparent" pygame.Surface()-object, because I needed it as a placeholder to assign the 2 images conditionally once a key(left or right) is pressed. Hence, the game starts and when not key is pressed no player shows up...
My question: How can I add a default (3rd) image before any key is actually pressed and not having the transparent Surface object hiding. I tried many things with the Surface.blit() or gameDisplay.blit() and thus loading another image, but it never showed up so far :(...
I guess it is a dumb thing to solve but I cannot figure it out on my own (+ google)..
Thanks in advance

Just assign one of the ges surfaces to player when the program starts instead of creating the transparent placeholder surface.

player = player.convert_alpha()
# Replace the lines above with this one.

How do I get random enemies to appear from list?

I'm trying to get a random car to appear from a list of cars saved in variables. The issue seems to be it chooses a random car from the list and doesn't change it while the game is being played. I'd like to change the car each time the previous car goes off screen.
Each time the game starts it chooses one car from the random list, but does not change the car each time the game loop runs.
I believe the problem lies in this bit of code
randomCars = [car1, car2, car3, car4, car5, car6, car7, car8]
enemy = random.choice(randomCars)

Here's a minimal example. Just use random.choice to get a new car out of the list as soon as the current car leaves the screen.
import random
import pygame
pygame.init()
CAR_IMG1 = pygame.Surface((30, 50))
CAR_IMG1.fill((10, 150, 200))
CAR_IMG2 = pygame.Surface((30, 50))
CAR_IMG2.fill((210, 150, 0))
CAR_IMG3 = pygame.Surface((30, 50))
CAR_IMG3.fill((10, 250, 0))
CARS = [CAR_IMG1, CAR_IMG2, CAR_IMG3]
def main():
screen = pygame.display.set_mode((640, 480))
screen_rect = screen.get_rect()
clock = pygame.time.Clock()
car = random.choice(CARS)
pos_x = random.randrange(screen_rect.width-30)
pos_y = -50
done = False
while not done:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
pos_y += 15
if pos_y > screen_rect.height:
car = random.choice(CARS)
pos_x = random.randrange(screen_rect.width-30)
pos_y = -50
screen.fill((30, 30, 30))
screen.blit(car, (pos_x, pos_y))
pygame.display.flip()
clock.tick(30)
if __name__ == '__main__':
pygame.init()
main()
pygame.quit()

First initialize your list of enemy car images from which to choose one.
randomCars = [carImg1, carImg2, carImg3, carImg4]
Inside the game_loop() function but outside of the main loop set enemy = random.choice(randomCars)
Inside the main loop of the game_loop() function check to see if the enemy went off the screen. If so, set the enemy variable to a new random car.
if thing_starty > display_height:
# Reset enemy image
enemy = random.choice(randomCars)
# Reset thing co-ordinates
thing_starty = -600
thing_startx = random.randrange(0, display_width)
If the enemy = random.choice(randomCars) line of code doesn't work you could also try indexing the randomCars list with a random integer.
randomCarsIndex = random.randint(0, len(randomCars) - 1)
enemy = randomCars[randomCarsIndex]
Hope this helps!

Using an image as an object in pygame, but it wont appear in the game frame

The image im trying to use is the drakeImg, which is supposed to drop from the top of the game frame, the game is working fine but i cannot see the drakeImg dropping from the top of the screen, all i can see is the boatImg and the background, but the dodged count and crash() still work.

How do I stop my game from restarting when my pause plays my game_loop function in pygame?

So, I am making a simple video game in pygame, and it is very close to finishing. I was working on my pause screen, but when I hit p(the button I chose) it paused but when I hit continue it restarted the game. I went over the code and found nothing wrong. Then, I went to the question forum here and looked up the issue, I found something but they arent doing the code like I am, and on top of that the answer is hard to understand. The pause function is paused() and the unpause is, suprise, unpause(). Can you try to find where it went wrong? Here is my scource code:

It seems that you do not unpause in your pause() function.
You should be adding something like this:
def paused():
while pause:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.K_p:
unpause()

In my code, I set the unpause button function to game_loop() instead of unpause(). So every time I went to unpause, I restarted the game loop! This is an example that you have to pay attention to every section of your code, not just the function thats going wrong.

Pygame (A bit racey) game bug

in the game when you first start it there's the game start menu/intro, it has 2 buttons (Start Game) (Quit)
Now when you start the game and you're actually playing, when you press P (Paused) there're 2 buttons (Continue) (Main Menu) if you click continue it completes the game normally. However when you click main menu it closes the game instead of returning to the intro, same problem is present when you crash with the car you have (Try Again) and (Main Menu) and also if you click Main Menu it closes the game
Any ideas on what might be the problem ?(ignore the comments)

Because you're not waiting for the mouse button to be released before you trigger your buttons.
When pause() starts, it brings up two buttons.
User moves mouse to Main Menu.
User clicks mouse.
As soon as the mouse button is depressed, game_intro() is called, which puts a Quit button in the same place.
The mouse button is still depressed, so the game quits.
