Question

import random
n = 1
tala = random.randrange(0,11)
print('talan er ' + str(tala))

print('The goal is to guess the number.')
num = input('Pick a number: ')

while num != tala:
    if num < tala:
        print('Too Low')
        num = input('Try again: ')
    elif num > tala:
        print('Too High')
        num = input('Try again: ')
    else:
        print('wow congratulations, you guessed the right number in ' + str(n) + ' tries.')
    n += 1

上面是我的代码，下面是我遇到的错误。

我似乎找不到我的错误：这只是一个简单的代码，但是我找不到该错误。

    Traceback (most recent call last):
  File "C:/Users/ebben/PycharmProjects/HelloWorld/GuessNumber.py", line 10, in <module>
    if num < tala:
TypeError: '<' not supported between instances of 'str' and 'int'

Answer 1

python输入始终是字符串，您需要通过添加int()方法

将其转换为整数

这是您的代码：您需要更改num：

import random
n = 1
tala = random.randrange(0,11)
print('talan er ' + str(tala))

print('The goal is to guess the number.')
num = int(input('Pick a number: '))

while num != tala:
    if num < tala:
        print('Too Low')
        num = int(input('Try again: '))
    elif num > tala:
        print('Too High')
        num = int(input('Try again: '))
    else:
        print('wow congratulations, you guessed the right number in ' + str(n) + ' tries.')
    n += 1

Answer 2

错误表明，少于<运算符和>运算符必须与number或int的{{1}}数据类型进行比较。这意味着变量float是num对象。

因此，替换以下行以解决您的错误：-

替换

string

进入

 if num < tala:

＆

替换

 if int(num) < tala:

进入

 if num > tala:

我的while循环由于某种原因无法正常运行
