Question

因此，一旦我运行代码，question()就会返回'Incorrect'，即使我非常确定我会给出正确答案。

P.S。我检查了operator()函数是否合适;它只是需要注意的question()。

import random

def numberRan(): # Generate a random number
   return random.randint(1, 10) # No arguments needed for this

def operator():
   operator = ""
   number = random.randint(1, 3)
   if number == 1:
      operator = "+"
   elif number == 2:
      operator = "-"
   else:
      operator = "x"
   return operator

def question():
   num1 = numberRan()
   num2 = numberRan()
   realAnswer = 0
   int(realAnswer)
   oper = operator()
   answer = input(str(num1) + str(oper) + str(num2) + "= ")
   if oper == "+":
      realAnswer = num1 + num2
   elif oper == "-":
      realAnswer = num1 - num2
   elif oper == "x":
      realAnswer = num1 * num2
   if realAnswer == answer:
      return "Correct"
   else:
      return "Incorrect"

question()

Answer 1

你永远不会将你的答案转换为int，所以你的答案（input(...)的结果仍然是str。你然后将str与realAnswer进行比较，这是一个int：比较一个int和str将始终为False。

只需更改一行：

answer = input(str(num1) + str(oper) + str(num2) + "= ")

到

try:
    answer = int(input(str(num1) + str(oper) + str(num2) + "= "))
except ValueError:
    import sys
    sys.stderr.write("your input was not an integer number")
    return "Incorrect"

if oper == "+":
    ...

请注意try-except子句：现在，如果输入不是数字，则会出现解释性错误消息。

Python代码不起作用 - 返回＆＃34;不正确＆＃34;
