如何一次问一个问题进行数学测验

Question

这应该用随机数和运算符生成随机数学测验。 我如何让它一次打印一个问题，如果他们得到正确的答案，请将其添加到他们的分数中？

score = 0

for i in range(10):
   ops=['+','-','*','//']
   num1 = random.randint(1,20)
   num2 = random.randint(1,20)
   if ops == '+':
       answer=num1+num2
   elif ops == '-':
       answer = num1-num2
   elif ops == '*':
       answer = num1*num2  
   elif ops == "//":
       answer == num1//num2
   print(num1,ops[random.randint(0,3)],num2,'=')
         

Answer 1

这是您的代码的固定版本。 你有几个错误。

• 您需要选择一个运算符（我在这里使用了random.choice ）

• answer == num1//num2需要一个简单的=

• 您可以使用input来请求用户输入

import random
n = 10
score = 0
for i in range(n):
   ops=['+','-','*','//']
   num1 = random.randint(1,20)
   num2 = random.randint(1,20)
   op = random.choice(ops)
   if op == '+':
       answer = num1+num2
   elif op == '-':
       answer = num1-num2
   elif op == '*':
       answer = num1*num2
   elif op == "//":
       answer = num1//num2
   try:
       test = int(input(f'{num1} {op} {num2} = '))
   except ValueError:
       print('invalid input')
       continue
   if answer == test:
       print('correct!')
       score += 1
   else:
       print(f'wrong, the answer was: {answer}')
print(f'you scored {score}/{n}')
