question:I want to make a simple game where the player must navigate through a maze. Here's a basic outline of what I want: - The maze will be a 2D grid of squares (e.g. 10x10) - Each square will be one of three types: empty, wall, or goal - The player can move up, down, left, or right, but they cannot move through walls - The game ends when the player reaches the goal I'd like to create a simple implementation of this game in Python. Here's some basic code to get started: ```python class Maze: def __init__(self, width, height): self.width = width self.height = height self.grid = [[0 for _ in range(width)] for _ in range(height)] def print_maze(self): for row in self.grid: print(' '.join(['
answer:class Maze: EMPTY = 0 WALL = 1 GOAL = 2 def __init__(self, width, height): self.width = width self.height = height self.grid = [[Maze.EMPTY for _ in range(width)] for _ in range(height)] self.player_position = (0, 0) def set_wall(self, x, y): self.grid[y][x] = Maze.WALL def set_goal(self, x, y): self.grid[y][x] = Maze.GOAL def print_maze(self): for y, row in enumerate(self.grid): for x, cell in enumerate(row): if self.player_position == (x, y): print('P', end=' ') elif cell == Maze.WALL: print('W', end=' ') elif cell == Maze.GOAL: print('G', end=' ') else: print('.', end=' ') print() def move_player(self, direction): x, y = self.player_position if direction == 'up': new_position = (x, y - 1) elif direction == 'down': new_position = (x, y + 1) elif direction == 'left': new_position = (x - 1, y) elif direction == 'right': new_position = (x + 1, y) else: return False if self.is_valid_move(*new_position): self.player_position = new_position return True return False def is_valid_move(self, x, y): if 0 <= x < self.width and 0 <= y < self.height: if self.grid[y][x] != Maze.WALL: return True return False def is_goal_reached(self): return self.grid[self.player_position[1]][self.player_position[0]] == Maze.GOAL
question:I have a binary file. I want to read it in chunks, then write those chunks to another file. How can I do this in Python?
answer:def copy_binary_file(source_file, destination_file, chunk_size=1024): Copies a binary file from source_file to destination_file in chunks of size chunk_size. :param source_file: Path to the source binary file :param destination_file: Path to the destination binary file :param chunk_size: Size of each chunk to be read and written (default 1024 bytes) with open(source_file, 'rb') as src, open(destination_file, 'wb') as dst: while True: chunk = src.read(chunk_size) if not chunk: break dst.write(chunk)
question:You should write a task that creates a simple and efficient way to handle a list of 5000 items using list comprehension in Python. **Task:** Write a Python function named `process_list` that takes a list of integers as input, and returns a new list that includes only the even numbers from the original list, but multiplied by 2. # Example: Input: `[1, 2, 3, 4, 5, 6]` Output: `[4, 8, 12]` # Constraints: - The function should be able to handle a list of 5000 items. - The function should use list comprehension. - The function should be efficient in terms of memory usage and execution time. # Evaluation Criteria: - Correctness: Does the function produce the correct output for the given input?
answer:def process_list(lst): Takes a list of integers and returns a new list containing only the even numbers from the original list, each multiplied by 2. Arguments: lst -- list of integers Returns: List of integers containing the even numbers from the original list, each multiplied by 2. return [x * 2 for x in lst if x % 2 == 0]
question:Here are two functions: ``` def function_1(x): return x*2 def function_2(x): return x*3 ``` I am trying to create a new function that takes in two functions as arguments and returns a new function. This new function should take in one argument and apply function_1 and function_2 to this argument in sequence. Here is what I have so far: ``` def compose_functions(func1, func2): def inner_function(x): return func2(func1(x)) return inner_function ``` How can I test the composition of function_1 and function_2 using this new function?
answer:def function_1(x): return x*2 def function_2(x): return x*3 def compose_functions(func1, func2): def inner_function(x): return func2(func1(x)) return inner_function
