使用Python的KBC游戏

---

简介

一个著名的印度游戏节目，叫做百万富翁 (Kaun Banega Crorepati, KBC)，是根据国际游戏节目“谁想成为百万富翁”改编的。在这篇文章中，我们将了解如何使用Python编程语言来制作一个简化的KBC游戏版本。

KBC

定义

在KBC游戏中，参赛者选择正确答案来回答多项选择题，以赢得奖金，奖金随着每次正确回答而增加。游戏的目标是从一系列包含多个选项的问题中选择正确的答案。每个正确答案都会获得一定金额的奖金，而错误答案则会导致游戏结束。

语法

变量 −

question - Stores the question text.
options - A list that contains multiple-choice options.
answer - Stores the index of the correct answer.

用户输入 −

input() - Reads user input from the console.

条件语句 −

if - Checks a condition and executes a block of code if the condition is true.
else - Executes a block of code if the preceding if statement condition is       false.

循环 −

for loop - Iterates over a sequence of elements.
while loop - Repeats a block of code until a condition is met.

• 在KBC游戏中，需要变量来存储问题、可能的答案和正确答案。为了显示问题和接收用户输入，这些变量至关重要。

• 用户输入 − 我们使用`input()`函数从控制台读取用户输入。然后，玩家可以通过输入相应的选项编号来选择他们的答案。

• 条件语句 − 为了比较用户的答案和正确答案，我们使用`if`和`else`之类的条件语句。如果用户的答案正确，则用户获得奖金。否则，游戏结束。

• 使用循环，我们可以遍历问题列表，一次向玩家提出一个问题。当我们希望游戏持续到满足某个条件时，`while`循环比较有用；而当我们有固定数量的问题时，`for`循环则更有效。

算法

• 步骤1 − 设置初始奖金金额。

• 步骤2 − 创建一个包含问题、选项和正确答案的列表。

• 步骤3 − 遍历问题列表。

• 步骤4 − 显示所有问题和答案。

• 步骤5 − 获取用户答案。

• 步骤6 − 检查用户答案是否与正确答案匹配。

• 步骤7 − 根据需要调整奖金金额。

• 步骤8 − 如果用户答案错误，游戏结束。

• 步骤9 − 重复步骤3，直到所有问题都已解答或游戏结束。

• 步骤10 − 显示玩家最终获得的奖金金额。

方法

• 方法1 − 使用`for`循环。

• 方法2 − 使用`while`循环

方法1：使用for循环

示例

# Importing the random module to shuffle questions
import random

# Set the initial amount of prize money
prize_money = 0

# Create a list of questions with options and answers
questions = [{
   "question": "What is the capital of India?",
   "options": ["1. Delhi", "2. Mumbai", "3. Kolkata", "4. Chennai"],
   "answer": 1
},{
   "question": "Which planet is known as the Red Planet?",
   "options": ["1. Jupiter", "2. Venus", "3. Mars", "4. Saturn"],
   "answer": 3
},{
   "question": "Who painted the Mona Lisa?",
   "options": ["1. Vincent van Gogh", "2. Pablo Picasso", "3. Leonardo da Vinci", "4. Claude Monet"],
   "answer": 3
}]

# Shuffle the questions
random.shuffle(questions)

# Iterate over the questions using a for loop
for question in questions:
   # Display the question and options
   print(question["question"])
   for option in question["options"]:
      print(option)
    
   # Read the user's answer
   user_answer = int(input("Enter your answer (option number): "))
    
   # Check if the user's answer is correct
   if user_answer == question["answer"]:
      print("Correct answer!")
      prize_money += 1000
   else:
      print("Wrong answer!")
      break  # End the game if the answer is incorrect

# Display the final prize money earned by the player
print("Prize Money:", prize_money)

输出

What is the capital of India?
1. Delhi
2. Mumbai
3. Kolkata
4. Chennai
Enter your answer (option number): 1
Correct answer!
Which planet is known as the Red Planet?
1. Jupiter
2. Venus
3. Mars
4. Saturn
Enter your answer (option number): 2
Wrong answer!
Prize Money: 1000

`random.shuffle()`函数用于在每次游戏时以不同的顺序打乱问题。

方法2：使用while循环

示例

 # Set the initial amount of prize money
prize_money = 0

# Create a list of questions with options and answers
questions = [{
   "question": "What is the capital of India?",
   "options": ["1. Delhi", "2. Mumbai", "3. Kolkata", "4. Chennai"],
   "answer": 1
},{
   "question": "Which planet is known as the Red Planet?",
   "options": ["1. Jupiter", "2. Venus", "3. Mars", "4. Saturn"],
   "answer": 3
},{
   "question": "Who painted the Mona Lisa?",
   "options": ["1. Vincent van Gogh", "2. Pablo Picasso", "3. Leonardo da Vinci", "4. Claude Monet"],
   "answer": 3
}]

# Set the initial question index
question_index = 0

# Set the initial game status
game_over = False

# Game loop
while not game_over:
   # Get the current question
   question = questions[question_index]
    
   # Display the question and options
   print(question["question"])
   for option in question["options"]:
      print(option)
    
   # Read the user's answer
   user_answer = int(input("Enter your answer (option number): "))
    
   # Check if the user's answer is correct
   if user_answer == question["answer"]:
      print("Correct answer!")
      prize_money += 1000
   else:
      print("Wrong answer!")
      game_over = True  # End the game if the answer is incorrect
    
   # Move to the next question
   question_index += 1
    
   # Check if all questions have been answered
   if question_index == len(questions):
      game_over = True

# Display the final prize money earned by the player
print("Prize Money:", prize_money)

输出

What is the capital of India?
1. Delhi
2. Mumbai
3. Kolkata
4. Chennai
Enter your answer (option number):1
Correct answer!
Which planet is known as the Red Planet?
1. Jupiter
2. Venus
3. Mars
4. Saturn
Enter your answer (option number): 3
Correct answer!
Who painted the Mona Lisa?
1.Vincent van Gogh
2. Pablo Picasso
3. Leonardo da Vinci 
4. Claude Monet
Correct answer!
Prize Money: 3000

使用`while`循环创建游戏循环，该循环持续运行直到游戏结束。如果用户给出错误答案或所有问题都已回答，则将游戏结束条件设置为`True`。

结论

总之，这是一个强大且灵活的基础，可以用来开发一个有趣的问答游戏，让玩家在娱乐和引人入胜的方式中测试他们的知识并赢取奖金。
