Python：循环问题或缩进

Question

Python 3.4

大家好！我在我的程序中需要布尔运算符的帮助。 您必须猜测程序设置的数字，从 1 到 1000。 如果您猜它表示做得好，如果不是，它表示高/低。

使用 While、if/elif/else（其中任何一种），以及 playagain 循环。

这是我目前所拥有的。

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

您的主要问题是您没有在循环中提示他们。

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

要提示用户是否希望再次播放，您可以执行以下操作：

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
