运行一个非常简单的Python程序的问题

Question

为什么我的程序在这里给我一个错误？

import random 

TheNumber = random.randrange(1,200,1) 
NotGuessed = True 
Tries = 0 

GuessedNumber = int(input("Take a guess at the magic number!: "))     

while NotGuessed == True: 
    if GuessedNumber < TheNumber: 
     print("Your guess is a bit too low.") 
     Tries = Tries + 1 
     GuessedNumber = int(input("Take another guess at the magic number!: ")) 

    if GuessedNumber > TheNumber: 
     print("Your guess is a bit too high!") 
     Tries = Tries + 1 
     GuessedNumber = int(input("Take another guess at the magic number!: ")) 

    if GuessedNumber == TheNumber: 
     print("You've guess the number, and it only took you " + string(Tries) + "!") 

错误在最后一行。我能做什么？

编辑：

另外，为什么能;吨我用尝试次数++这里在Python？没有自动增量代码吗？

编辑2：错误是：

Traceback (most recent call last): 
    File "C:/Users/Sergio/Desktop/GuessingGame.py", line 21, in <module> 
    print("You've guess the number, and it only took you " + string(Tries) + "!") 
NameError: name 'string' is not defined 

Answer 1

它str，不string。但是你的无限循环是一个更大的问题。自动递增是这样写的：

Tries += 1 

一般性意见：你可以提高你稍微的代码：

the_number = random.randrange(1,200,1) 
tries = 1 

guessed_number = int(input("Take a guess at the magic number!: ")) 
while True: 
    if guessed_number < the_number: 
     print("Your guess is a bit too low.") 

    if guessed_number > the_number: 
     print("Your guess is a bit too high!") 

    if guessed_number == the_number: 
     break 
    else: 
     guessed_number = int(input("Take another guess at the magic number!: ")) 
     tries += 1 

print("You've guessed the number, and it only took you %d tries!" % tries)

在你的最后一行，与str替换string - 应该采取错误的护理至少，python抱怨着。
