python爬虫初体验（五）—— 边学边玩小游戏
1. 打开浏览器
利用webbrowser 模块的 open()函数可以启动一个新浏览器，打开指定的 URL。
import webbrowser
webbrowser.open('http://inventwithpython.com/')
2. 猜数字游戏
# -*- coding: utf-8 -*-
# This is a guess the number game.
import random
secretNumber = random.randint(1, 20)
print('I am thinking of a number between 1 and 20.')
# Ask the player to guess 6 times.
for guessesTaken in range(1, 7):
print('Take a guess.')
guess = int(input())
if guess < secretNumber:
print('Your guess is too low.')
elif guess > secretNumber:
print('Your guess is too hight.')
else:
break # This condition is the correct guess!
if guess == secretNumber:
print('Good job！You guessed my number in ' + str(guessesTaken) + ' guesses!')
else:
print('Nope. The number I was thinking of was ' + str(secretNumber))
3. 贪吃蛇游戏

curses.curs_set(0)
# 设置非阻塞输入模式
stdscr.nodelay(1)

# 获取屏幕的高度和宽度
sh, sw = stdscr.getmaxyx()
# 初始化蛇的位置，初始时蛇只有一个单元格
snake = [(sh//2, sw//2)]
# 初始方向为向右
direction = curses.KEY_RIGHT
# 随机生成食物的位置
food = (random.randint(1, sh-2), random.randint(1, sw-2))
# 在屏幕上显示食物
stdscr.addch(food[0], food[1], '*')
while True:
# 获取用户输入的按键

# 根据用户输入更新方向

new_head = (head[0] - 1, head[1])
elif direction == curses.KEY_DOWN:
new_head = (head[0] + 1, head[1])
# 将新的蛇头插入到蛇的头部
snake.insert(0, new_head)
# 如果新的蛇头位置与食物位置相同，则生成新的食物
if snake[0] == food:
food = (random.randint(1, sh-2), random.randint(1, sw-2))
stdscr.addch(food[0], food[1], '*')
else:
# 如果没有吃到食物，移除蛇尾
tail = snake.pop()
stdscr.addch(tail[0], tail[1], ' ')
# 检查游戏是否结束
if (snake[0][0] in [0, sh-1] or
snake[0][1] in [0, sw-1] or
snake[0] in snake[1:]):
# 显示游戏结束信息
stdscr.addstr(sh//2, sw//2 - 5, "Game Over!")
stdscr.refresh()
# 暂停2秒
curses.napms(2000)
break
# 在屏幕上显示新的蛇头
stdscr.addch(snake[0][0], snake[0][1], '#')
# 使用curses.wrapper来初始化和清理curses环境
curses.wrapper(main)
