Python：循環問題或縮進

Question

Python 3.4

嗨，大家好！我在程序中需要布爾運算符的幫助。 你必須猜測一個由程序設置的數字，從1 - 1000. 如果你猜測它說的很好，如果不是它說高/低。

使用while，if/elif/else（其中任何一個），以及playagain循環。

這是我到目前爲止。

import random 

a = int(input("I have a number between 1 and 1000. Can you guess my number?\nPlease type your first guess.")) 
x = random.randrange(1,1000) 
counter = 0 
b = False 
while not b: 
    if a == x: 
     print ("Excellent! You guessed the number in", counter1,"tries.") 
     b = True 
    elif a > x: 
     print ("high") 
     counter = counter + 1 

    elif a < x: 
     print ("low") 
     counter = counter + 1 

Answer 1

您的主要問題是您沒有在循環中提示他們。

import random 

x = random.randrange(1,1000)  
counter = 0 

while True: 
    guess = int(input("I have a number between 1 and 1000. Can you guess my number?\nPlease type your first guess.")) 
    if guess == x: 
     print ("Excellent! You guessed the number in", counter,"tries.") 
     break 
    else: 
     if guess > x: 
      print("high") 
     else: 
      print("low") 
     counter += 1 

提示用戶，如果他們想再次播放，你會做到以下幾點：

import random 

x = random.randrange(1,1000)  
counter = 0 

while True: 
    guess = int(input("I have a number between 1 and 1000. Can you guess my number?\nPlease type your first guess.")) 
    if guess == x: 
     print ("Excellent! You guessed the number in", counter,"tries.") 
     play_again = input("Type Y if you'd like to play again, or N if not") 
     if play_again == 'N': 
      break 
    else: 
     if guess > x: 
      print("high") 
     else: 
      print("low") 
     counter += 1
