question:You are given an array of integers representing the heights of buildings. The size of the array represents the street length. Your task is to calculate the amount of sunlight each building receives. A building receives sunlight if there are no taller buildings to its left. Example: ``` buildings = [2, 1, 3, 2, 4] sunlight = [2, 1, 3, 1, 4] Explanation: - Building at index 0 (height 2) receives 2 units of sunlight. - Building at index 1 (height 1) receives 1 unit of sunlight. - Building at index 2 (height 3) receives 3 units of sunlight. - Building at index 3 (height 2) receives 1 unit of sunlight. - Building at index 4 (height 4) receives 4 units of sunlight. ``` Can you provide a Python solution to this problem?
answer:def calculate_sunlight(buildings): Calculate the amount of sunlight each building receives. Args: buildings (list of int): List of building heights. Returns: list of int: List of sunlight units each building receives. sunlight = [] max_height = 0 for height in buildings: if height > max_height: max_height = height sunlight.append(max_height) return sunlight
question:Here is some code: ```python import random def guess_the_number(): Plays a number guessing game with the user. number = random.randint(1, 100) guesses_left = 7 print("I'm thinking of a number between 1 and 100.") while guesses_left > 0: print(f"You have {guesses_left} guesses left.") try: guess = int(input("Enter your guess: ")) except ValueError: print("Invalid input. Please enter a number.") continue if guess < number: print("Too low!") elif guess > number: print("Too high!") else: print(f"Congratulations! You guessed the number in {7 - guesses_left} tries!") return guesses_left -= 1 print(f"You ran out of guesses. The number was {number}.") guess_the_number() ``` This code implements a number guessing game where the computer chooses a random number between 1 and 100, and the player has 7 attempts to guess it. Can you add features to this game?
answer:import random def get_random_number(): return random.randint(1, 100) def check_guess(guess, number, attempts): if guess < number: return "Too low!" elif guess > number: return "Too high!" else: return f"Congratulations! You guessed the number in {attempts} tries!" def provide_hint(number): if number % 2 == 0: return "Hint: The number is even." else: return "Hint: The number is odd." def guess_the_number(): Plays a number guessing game with the user. games_won = 0 while True: number = get_random_number() guesses_left = 7 print("nI'm thinking of a number between 1 and 100.") while guesses_left > 0: print(f"You have {guesses_left} guesses left.") try: guess = int(input("Enter your guess: ")) except ValueError: print("Invalid input. Please enter a number.") continue result = check_guess(guess, number, 7 - guesses_left) print(result) if "Congratulations" in result: games_won += 1 break guesses_left -= 1 if guesses_left == 4: print(provide_hint(number)) if guesses_left == 0: print(f"You ran out of guesses. The number was {number}.") print(f"Games won: {games_won}") play_again = input("Would you like to play again? (yes/no): ").strip().lower() if play_again != 'yes': print("Thanks for playing! Goodbye!") break
question:Objective: Develop a Python script named `text_analyzer.py` that analyzes the textual content of a file. 2. File Input: - The script should accept the filename as a command-line argument. For example: ```bash python text_analyzer.py my_document.txt ``` 3. Analysis: - Word Count: Count the total number of words in the file. - Character Count: Count the total number of characters in the file (excluding whitespace). - Line Count: Count the total number of lines in the file. - Sentence Count: Count the total number of sentences in the file (assuming sentences end with ".", "!", or "?
answer:import sys import re def count_words(text): Returns the total number of words in the input text. words = text.split() return len(words) def count_characters(text): Returns the total number of characters in the input text (excluding whitespace). characters = re.sub(r's+', '', text) return len(characters) def count_lines(text): Returns the total number of lines in the input text. lines = text.split('n') return len(lines) def count_sentences(text): Returns the total number of sentences in the input text assuming sentences end with ".", "!", or "?". sentences = re.split(r'[.!?]', text) sentences = [sentence for sentence in sentences if sentence.strip() != ''] return len(sentences) def analyze_file(filename): Analyzes the file and prints the word count, character count, line count, and sentence count. try: with open(filename, 'r') as file: text = file.read() word_count = count_words(text) character_count = count_characters(text) line_count = count_lines(text) sentence_count = count_sentences(text) print(f'Word Count: {word_count}') print(f'Character Count: {character_count}') print(f'Line Count: {line_count}') print(f'Sentence Count: {sentence_count}') except FileNotFoundError: print(f'Error: File "{filename}" not found.') if __name__ == '__main__': if len(sys.argv) != 2: print("Usage: python text_analyzer.py <filename>") else: analyze_file(sys.argv[1])
question:This is what I am trying to achieve and the code I have so far: **Goal:** I want to build a simple text-based adventure game in Python where the player navigates through different rooms described by text and makes choices that affect the story. **What I Have:** ```python rooms = { "hallway": { "description": "You are in a dimly lit hallway. There is a door to the north and a door to the east.", "north": "bedroom", "east": "kitchen", }, "bedroom": { "description": "A small, tidy bedroom. There is a window to the west.", "west": "hallway", }, "kitchen": { "description": "A cluttered kitchen. There is a door to the west.", "west": "hallway", }, } current_room = "hallway" while True: room = rooms[current_room] print(room["description"]) action = input("> ") if action in room: current_room = room[action] else: print("Invalid direction.") ``` **What I Need Help With:** I need help with the following: 1. **Clearer Input Handling:** - The current code only accepts compass directions (north, east, west, etc.). I want it to be more flexible, allowing players to type full sentences like "go north," "open door," or "examine table." 2. **Adding Items:** I'd like to add items to rooms that players can pick up and use. 3. **Implementing Actions:** - I want to expand beyond just movement. I'd like players to be able to interact with objects, solve puzzles, or engage in simple combat. 4. **Saving and Loading Progress:** - It would be great to allow players to save their game and load it later. **Can you guide me on how to implement these features?
