Question

为什么太低，太高并且反复打印很多次？

这是我的代码：

import random
name = input("Hello there! What's your name?\n")
print("Hello there", name, ". Welcome to GUESS THE NUMBER GAME")
number = random.randint(1,100)
guess = int(input("Please guess a number"))
n=1
while n<10:
    if guess < number:
        print("Too low")

    elif guess > number:       
        print("Too high")

    elif guess == number:        
        print("Got it")

    n=n+1

Answer 1

您需要将<{1}} 移动到循环中，来自：

guess

为：

guess = int(input("Please guess a number"))
n=1
while n<10:
    if guess < number:
        print("Too low")

    elif guess > number:       
        print("Too high")

    elif guess == number:        
        print("Got it")

    n = n+1

此外，您可以简化：

n = 1
while n < 10:
    guess = int(input("Please guess a number"))
    if guess < number:
        print("Too low")

    elif guess > number:       
        print("Too high")

    elif guess == number:        
        print("Got it")

    n += 1

当用户做出正确的猜测时应该for _ in range(9): guess = int(input("Please guess a number")) ...：

break

Answer 2

这是你真正的缩进吗？

如果是的话：

while n<10:
    if guess < number:
        print("Too low")
    elif guess > number:       
        print("Too high")
    elif guess == number:        
        print("Got it")

，最后elif guess == number:可以只是else;）

编辑：我忘记了你的n ++和真正的问题：输入

这样：

while n<10:
    guess = int(input("Please guess a number"))
    n = n+1
    if guess < number:
        print("Too low")
    elif guess > number:       
        print("Too high")
    else:
        print("Got it")

并退出循环：

while n<10:
    guess = int(input("Please guess a number"))
    n = n+1
    if guess < number:
        print("Too low")
    elif guess > number:       
        print("Too high")
    else:
        print("Got it in "+n+" attempts.")
        n=11

假设您提供的代码具有正确的缩进，那么因为n = n + 1语句不在while循环中。更正的代码是：

import random
name = input("Hello there! What's your name?\n")
print("Hello there", name, ". Welcome to GUESS THE NUMBER GAME")
number = random.randint(1,100)
guess = int(input("Please guess a number"))
n=1
while n<10:
    if guess < number:
        print("Too low")

    elif guess > number:       
        print("Too high")

    elif guess == number:        
        print("Got it")

    n=n+1

一条建议（假设您使用的是Python 2.X）：使用raw_input()代替input，因为raw_input会自动将输入解析为字符串，而input 1}}允许用户注入任意python代码。

ETA：正如其他人所指出的，猜测语句（guess = int(input("Please guess a number"))）应该移入while循环，如果猜测正确则使用break语句。

如果print语句重复很多次
