基本Python代码不工作

Question

我是Python的新手。 这是我的代码，执行二进制搜索找到猜测的数字。我无法正确地弄清楚如何使我的代码工作。 任何帮助，将不胜感激。谢谢。

print"Please think of a number between 0 and 100!" 



guessed=False 
while not guessed: 
    lo=0 
    hi=100 
    mid=(lo+hi)/2 
    print'Is you Secret Number'+str(mid)+'?' 
    print"Enter 'h' to indicate the guess is too high.", 
    print"Enter'l' to indicate the guess is too low", 
    print"Enter'c'to indicate I guessed correctly" 
    x=raw_input() 
    if(x=='c'): 
     guessed=True 
    elif(x=='h'): 
     #Too High Guess 
     lo=mid+1 
    elif(x=='l'): 
     lo=mid-1 
    else: 
     print("Sorry, I did not understand your input.") 
print'Game Over','Your Secret Number was'+str() 

Answer 1

以下几点需要申请代码：

1. 定义下限和上限for循环之外becsue如果我们里面while loop定义，每次lo和hi变量将与0和100值分别创建。
2. 根据变量工作给变量名称。

lower = 0 higher = 100

神实践Write函数包裹代码。

由于猜测数为更高然后设置最大数量猜数。 由于猜数是较低然后设置最小数字猜数。

演示：

import time 


def userNoInput(msg): 
    """ Get Number into from the user. """ 
    while 1: 
     try: 
      return int(raw_input(msg)) 
     except ValueError: 
      print "Enter Only Number string." 
      continue 


def guessGame(): 
    """ 
     1. Get Lower and Upeer Value number from the User. 
     2. time sleep to guess number for user in between range. 
     3. While infinite loop. 
     4. Get guess number from the Computer. 
     5. User can check guess number and tell computer that guess number if correct ror not. 
     6. If Correct then print msg and break While loop. 
     7. If not Correct then 
      Ask Computer will User that guess number is Greate or Lower then Actual number. 
      7.1. If Greater then Set Max limit as guess number. 
      7.2. If Not Greater then Set Min limit as guess number. 
      7.3. Continue While loop 
    """ 
    min_no = userNoInput("Please input the low number range:") 
    max_no = userNoInput("Please input the high number range:") 
    print "Guess any number between %d and %d."%(min_no, max_no) 
    time.sleep(2) 

    while True: 
     mid = (min_no+max_no)/2 
     print'Is you Secret Number'+str(mid)+'?' 
     print"Enter 'h' to indicate the guess is too high.", 
     print"Enter'l' to indicate the guess is too low", 
     print"Enter'c'to indicate I guessed correctly" 
     x=raw_input().lower() 
     if(x=='c'): 
      print'Game Over','Your Secret Number was'+str(mid) 
      break 
     elif(x=='h'): 
      #- As guess number is higher then set max number to guess number. 
      max_no=mid - 1 
     elif(x=='l'): 
      #- As guess number is lower then set min number to guess number. 
      min_no = mid + 1 
     else: 
      print("Sorry, I did not understand your input.") 

guessGame()
