My code is

#!/Library/Frameworks/Python.framework/Versions/3.6/bin/


import sys;
import log;


# Initialization
print(log.GetTime());

import pygame;
import turtle;


pygame = pygame;
turtle = turtle;

# After Initialization
pygame.init();
turtle.begin_fill();

player = {
    'speed': {
        'move': 5,
        'rotate': 1
    }
};

while true:
    time = log.GetTime();
    keys = pygame.key.get_pressed();

    if keys[K_ESCAPE]: break;
    if keys[K_W]: turtle.forward(player.speed.move);
    if keys[K_S]: turtle.backward(player.speed.move);
    if keys[K_A]: turtle.left(player.speed.rotate);
    if keys[K_D]: turtle.right(player.speed.rotate);

print('Ended program!');

I am very very new to python programming, and have no experience in what this is. I have tried looking for answers to fix this, but quite hard when I don't know what's wrong, could anyone tell me how I could fix the issue? What did I do wrong?

Answer 1

Here I will point out your mistakes and how to solve your problem.

1. true is called True in python
2. K_ESCAPE , K_W ... isn't defined, I don't know where you got your names from but you gotta figure that out yourself. You probably meant pygame.K_ESCAPE , pygame.K_w ...note: they are lower cased
3. python does not require ; at every line breaks
4. you do not need pygame = pygame and turtle = turtle since the import comes with the names
5. getting item from dict uses [] not .
6. calling turtle's left/right turns the cursor by that angle not move left/right

And here's how you can stop it from crashing:

import sys
import log


# Initialization
print(log.GetTime())

import pygame
import turtle


# After Initialization
turtle.begin_fill()
pygame.init()


player = {
    'speed': {
        'move': 5,
        'rotate': 1
    }
};

while True:
    time = log.GetTime()
    keys = pygame.key.get_pressed()

    if keys[pygame.K_ESCAPE]: break
    if keys[pygame.K_W]: turtle.forward(player['speed']['move'])
    if keys[pygame.K_S]: turtle.backward(player['speed']['move'])
    if keys[pygame.K_A]: turtle.left(player['speed']['rotate'])
    if keys[pygame.K_D]: turtle.right(player['speed']['rotate'])

print('Ended program!')

You will need to swap places with turtle.begin_fill() and pygame.init() since both pygame and turtle uses the base module tkinter , but only one Tk() (the window) is allowed at a time, but turtle does not know how to use the existing window that pygame created, so the app crashed. While pygame knows how to use the existing window turtle created.

As a side note, it's not necessary to use pygame with turtle, just use tkinter and it has way more functionalities. Plus, you don't even need either of them, turtle have enough functions to do what you wanted.

EDIT: pygame and turtle will never work well together. recommend using tkinter.
