如何使我的python代码正常工作?随机数学测验

Question

这是我的代码，它必须在代码中有+ - *，并且必须随机选择，但它不起作用，它没有说出正确的答案。我很感激任何帮助，谢谢。

import random
import operator
question_number = 0
score = 0
ops = {'+':operator.add,
           '-':operator.sub,
           '*':operator.mul,
           '/':operator.truediv}
number1 = random.randint(0,12)
number2 = random.randint(1,10)
op = random.choice(list(ops.keys()))
print ("this is a short maths quiz")
name = input ("what is your name")
age = input ("how old are you " +name)
print ("ok "+name+" im going to start the quiz now")
print(number1, op, number2)
user_input=int(input())
answer = (number1,op,number2)
if user_input == answer:
    print("Well done")
    score = score + 1
else:
    print("WRONG!")
    print("The answer was",answer)
question_number = question_number + 1

Answer 1

您需要将op作为键，以从ops dict和call中获得两个数字上的适当值：

answer = ops[op](number1, number2)

您的代码正在将int与元组（即9 == (3, '+', 6) ）进行比较

除非您想要负数，否则您可能还希望将较大的数字保留在左侧，将较小的数字保持在右侧。

answer = ops[op](max(number1,number2),min(number1, number2))

此外，除非这是在一段时间内，否则循环question_number = question_number + 1不会有太大作用。

Answer 2

您需要将op设为op，而不是字符串。这是您修复的代码。

import random
import operator
question_number = 0
score = 0
ops = {'+':operator.add,
           '-':operator.sub,
           '*':operator.mul,
           '/':operator.truediv}
number1 = random.randint(0,12)
number2 = random.randint(1,10)
op = random.choice(list(ops.keys()))
print ("this is a short maths quiz")
name = input ("what is your name")
age = input ("how old are you " +name)
print ("ok "+name+" im going to start the quiz now")
print(number1, op, number2)
user_input=int(input())
if op == "+":
    answer = (number1+number2)
elif op == "-":
    answer = (number1-number2)
elif op == "*":
    answer = (number1*number2)
elif op == "/":
    answer = (number1/number2)
if user_input == answer:
    print("Well done")
    score = score + 1
else:
    print("WRONG!")
    print("The answer was",answer)
question_number = question_number + 1

您可以添加一个while循环，使其重复
