Python编程：循环、错误检查与列表的应用

1. 猜数字游戏基础实现

猜数字游戏是一个经典的编程示例，通过它可以学习循环、随机数生成和用户输入处理等知识。

1.1 代码实现

import random
MAX_GUESSES = 5  # 最大猜测次数
MAX_RANGE = 20  # 最大数字范围

# 显示介绍信息
print 'Welcome to my Guess the Number program.'
print 'Guess my number between 1 and', MAX_RANGE
print 'You will have', MAX_GUESSES, 'guesses.'

target = random.randrange(1, MAX_RANGE + 1)
guessCounter = 0

while True:
    userGuess = raw_input('Take a guess: ')
    userGuess = int(userGuess)
    guessCounter = guessCounter + 1

    if userGuess == target:
        print 'You got it!'
        print 'It only took you', guessCounter, 'guess(es).'
        break
    elif userGuess < target:
        print 'Your guess was too low.'
    else:
        prin
