Question

我猜测了Python 3.6中的数字程序，这是我的代码。

import random
guesses = 0
print('Hello! What is your name?')
name = input()
num = random.randint(1,10)
print('well',name,'I am thinking of a number between 1 and 20.')
while guesses < 4:
    print('Take a guess.')  
    guess = input()
    guess = int(guess)
    guesses = guesses + 1

    if guess < num:
        print('Your guess is too low.')

    if guess > num:
             print('Your guess is too high.')
    if guess == num:
        guesses = str(guessesTaken)
        print('Good job, ',name,'! You guessed my number in ',guesses,' guesses!')

    if guess != num:
         num = str(num)
         print('Nope. The number I was thinking of was ',num)

当我运行我的代码时，它会显示此错误消息

Hello! What is your name?
h
well h I am thinking of a number between 1 and 20.
Take a guess.
7
Your guess is too low.
Nope. The number I was thinking of was  10
Take a guess.

Traceback (most recent call last):
  File "C:\Users\user\Desktop\Number game.py", line 13, in <module>
    if guess < num:
TypeError: '<' not supported between instances of 'int' and 'str'

为什么它支持＆gt;但不是＆lt; ？感谢所有帮助。

在Python中，print函数很乐意将对象转换为字符串，您不需要这样做。在此代码的情况下，您尝试在打印之前将对象转换为字符串，破坏了变量供以后使用。所以，只需删除这两行，您的代码似乎工作正常：

guesses = str(guessesTaken)

num = str(num)

TypeError：'＆lt;' 'int'和'str'实例之间不支持
