程序介绍：
猜数字小游戏，计算机随机生成一个1-100的数字，然后用户猜数字的值，系统提示用户：“数字太高了/数字太低了”。
代码部分：
#原版1
import random
n = random.randint(1,100) #生成一个1-100的随机整数
step = 0 #游戏的步数
print('Game start')
guess = int(input('Please enter an integer from 1 to 100:'))
while True:
step+=1
print('step',step)
if guess<n :
print(guess,'is low')
elif guess>n:
print(guess,'is high')
else:
print('You win!')
break
guess = int(input('Please enter an integer from 1 to 100:'))
print('Game over')
结果：
游戏存在bug,
1、输入非数字字符会报错
2、游戏没有退出功能
#改进2 解决BUG 输入0退出游戏
import random
n = random.randint(1,100) #生成一个1-100的随机整数
step = 0 #游戏的步数
print('Game start')
def get_number():
guess = input('Please enter an integer from 1 to 100:')
while True:
if guess.isdigit():#判断输入内容是否是数字
guess = int(guess)
return guess
else:
guess = input('Please enter an integer from 1 to 100:')
guess = get_number()#获取输入数字
while True:
step+=1
print('step',step)
if guess == 0:#退出游戏
print('quit')
break
if guess<n :
print(guess,'is low')
elif guess>n:
print(guess,'is high')
else:
print('You win!')
break
guess = get_number()
print('Game over')
结果2
Game start
Please enter an integer from 1 to 100:50
step 1
50 is high
Please enter an integer from 1 to 100:0 #按0退出游戏
step 2
quit
Game over
#改进3 增加提示，降低游戏难度，增加提示区间
import random
n = random.randint(1,100) #生成一个1-100的随机整数
step = 0 #游戏的步数
high = 100
low = 1
print('Game start')
def get_number():
guess = input('Please enter an integer from 1 to 100:')
while True:
if guess.isdigit():#判断输入内容是否是数字
guess = int(guess)
return guess
else:
guess = input('Please enter an integer from 1 to 100:')
guess = get_number()
while True:
step+=1
print('step',step)
if guess == 0:#退出游戏
print('quit')
break
if guess<n :
print(guess,'is low')
low = guess + 1
elif guess>n:
print(guess,'is high')
high = guess - 1
else:
print('You win!')
break
print('You can try',low,'to',high)
guess = get_number()
print('Game over')
结果
Game start
Please enter an integer from 1 to 100:50
step 1
50 is low
You can try 51 to 100
Please enter an integer from 1 to 100:80
step 2
80 is high
You can try 51 to 79
Please enter an integer from 1 to 100:60
step 3
60 is high
You can try 51 to 59
Please enter an integer from 1 to 100:55
step 4
55 is high
You can try 51 to 54
Please enter an integer from 1 to 100:53
step 5
You win!
Game over
