如何一次問一個問題進行數學測驗

Question

這應該用隨機數和運算符生成隨機數學測驗。 我如何讓它一次打印一個問題，如果他們得到正確的答案，請將其添加到他們的分數中？

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

這是您的代碼的固定版本。 你有幾個錯誤。

• 您需要選擇一個運算符（我在這里使用了random.choice ）

• answer == num1//num2需要一個簡單的=

• 您可以使用input來請求用戶輸入

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}')
