Question

我正在做一个测验来帮助我修改天文学，但是即使我正确输入了代码，这个错误也出现了：

What is the diameter of the Earth? 13000
Traceback (most recent call last):
   File "C:/Users/reddo/Documents/Python stuff/Astronomy quiz.py", line 19, in <module>
        elif answer1 >= 13001:
    TypeError: '>=' not supported between instances of 'str' and 'int'
    >>>

以下是我编写代码的方式：

answer1 = 13000 
answer1 = input ("What is the diameter of the Earth? ")

if answer1 == 13000:
    print("Correct!")

elif answer1 >= 13001:
    print ("Incorrect!")

elif answer1 <= 12999:
    print ("Incorrect!")

我不知道我是否出错了，或者只是程序本身。

Answer 1

您应该将其从字符串转换为整数

answer1 = int(input ("What is the diameter of the Earth? "))

Answer 2

answer1是一个字符串，因此您无法将其与整数进行比较。用以下内容替换第二行，将其转换为整数：

answer1 = int(input("What is the diameter of the Earth? "))

语法错误未知 - 大于或等于
