Python

开发一个

猜数小游戏

。在游戏中，程序每一轮会根据

玩家所选难度

随机生成一个的数字，玩家输入猜测的数字，程序告诉玩家猜大了还是猜小了。在一定次数内猜对，则本轮玩家获胜，并加分；否则本轮玩家失败，显示答案。

每一轮开始时，程序会要求玩家输入玩家名，并存放在

玩家数据字典

。玩家输入“

Y

”，开始这一轮游戏。玩家输入“

N

”，结束这一轮游戏。在每一轮游戏开始前，输入“

H

”可以查看该玩家的输入

历史数据

。在每一轮游戏中，存放玩家数据（

得分score，每轮答案answer，历史猜测guess

）到

玩家数据字典

中。

代码雏形

from random import *
difficulty = {'A' : 7,
			'B' : 8,
			'C' : 9,
			'D' : 10,}

user = input('Please input your name:')
print(f'Hello, smart {user}.\n\nThis is a game about guessing figure!\n')
difficulty_state = input(f'Please select the difficulty of the game!\n(A.easy B.medium C.difficult D.nightmare)：')
game_state = input('Are you ready?(Y/N):')

while game_state == 'Y':
	times = difficulty.get(difficulty_state,7)
	answer = randint(0,2 ** difficulty.get(difficulty_state,7))
	print(f'The answer is between 0 to {2 ** difficulty.get(difficulty_state,7)},and you have {times} opportunities!')
	
	while times > 0:
		user_answer = input('Please guess:\n')
		user_answer = int(user_answer)
		if user_answer == answer:
			break
		elif user_answer > answer:
			print('The number that you guess is bigger than answer!\n')
			times -= 1
		else:
			print('The number that you guess is smaller than answer!\n')
			times -= 1
		pass
	pass

	if times > 0:
		print('YOU WIN !\n')
		break
	else:
		print('YOU FAILED T-T\n')
		print(f'The answer is {answer}')
		break
	pass
pass

部分分析

1、

困难字典


困难字典是存放困难程度所对应数字的字典。本次设计困难字典对应数字为可猜测次数，而随机数取值范围与猜测次数有关，因此随机数取值范围和猜测次数均与困难字典对应数字有关。

其中，随机数取值下限为0，取值上限 = 2 ^ 猜测次数

"""存放困难程度的字典"""
difficulty = {'A' : 7,
			'B' : 8,
			'C' : 9,
			'D' : 10,}

self.times = difficulty.get(self.difficulty_state,7)

self.low = 0
self.high = 2 ** difficulty.get(self.difficulty_state,7)

2、随机数问题，因此需要调用random库,并采用randint函数

from random import *

答案

随机数选取

：

self.answer = randint(0,2 ** difficulty.get(self.difficulty_state,7))

3、

玩家数据字典


初始化玩家数据字典：

Users = {}

玩家数据字典结构

：

Users = {user1:{'score':score1,
				'answer':[answer],
				'guess':[guess1_1,guess1_2,……],},
		 user2:{'score':score2,
				'answer':[answer2],
				'guess':[guess2_1,guess2_2,……],},
			·
			·
			·
							}

对玩家数据字典的操作：

Users[self.user]['score'] += 5
Users[self.user]['answer'].append(self.answer)
Users[self.user]['guess'].append(self.user_answer)
