2.1 “猜数字”游戏

这是一个经典的编程入门项目，可以帮助你理解循环和条件语句。

import random

def guess_number():
    number_to_guess = random.randint(1, 100)
    attempts = 0

    print("Welcome to the Guess the Number Game!")
    print("I'm thinking of a number between 1 and 100.")

    while True:
        try:
            user_guess = int(input("Enter your guess: "))
            attempts += 1

            if user_guess < number_to_guess:
                print("Too low, try again.")
            elif user_guess > number_to_guess:
                print("Too high, try again.")
            else:
                print(f"Congratulations! You guessed the right number {number_to_guess} in {attempts} attempts.")
                break
        except ValueError:
            print("Please enter a valid integer.")

2.2 “贪吃蛇”游戏

“贪吃蛇”是一个经典的街机游戏，适合学习图形用户界面编程（GUI）。

import turtle

# 初始化屏幕
wn = turtle.Screen()

    if head.direction == "up":
        y = head.ycor()
        head.sety(y + 20)

    if head.direction == "down":
        y = head.ycor()
        head.sety(y - 20)

    if head.direction == "left":
        x = head.xcor()
        head.setx(x - 20)

    if head.direction == "right":
        x = head.xcor()
        head.setx(x + 20)

# 键盘绑定
wn.listen()
wn.onkeypress(go_up, "w")
wn.onkeypress(go_down, "s")
wn.onkeypress(go_left, "a")

    if head.xcor() > 290 or head.xcor() < -290 or head.ycor() > 290 or head.ycor() < -290:
        time.sleep(1)
        head.goto(0, 0)
        head.direction = "stop"

        # 隐藏段落
        for segment in segments:
            segment.goto(1000, 1000)
        segments.clear()

        # 重置分数
        score = 0
        score_board.clear()
        score_board.write("Score: {}  High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

    # 检查是否撞到食物
    if head.distance(food) < 20:
        x = random.randint(-290, 290)
        y = random.randint(-290, 290)

    time.sleep(0.1)

wn.mainloop()

2.3 “猜单词”游戏

这个游戏可以帮助你练习数据结构和算法，同时增加英语词汇量。

import random

# 单词列表
words = ["python", "algorithm", "variable", "loop", "function"]

# 随机选择一个单词
target_word = random.choice(words)

# 用于隐藏单词的字符列表
hidden_word = ["_" for _ in target_word]

# 游戏主循环
while True:
    print("".join(hidden_word))

    # 获取用户猜测的字母
    guess = input("Guess a letter: ").lower()

    # 检查猜测是否在目标单词中
    if guess in target_word:
        for index, letter in enumerate(target_word):
            if letter == guess:
                hidden_word[index] = letter

    # 检查游戏是否结束
    if "_" not in hidden_word:
        print("Congratulations! You've guessed the word: {}".format(target_word))
        break

    # 如果猜测错误，给出提示
    else:
        print("Try again!")
