Question

我的代码中的错误在哪里？我无法找到它们。我不得不制作一个乘法学习程序，但我现在陷入困境。

    import random

n = int(input("How many exercises?"))
wrong = 0
abort = False
for k in range(n):
    a = random.randint(2, 13)
    b = random.randint(2, 13)
    help = str(k+1) + ". " + str(a) + " * " + str(b)
    answer = input(help + "=> ")
    if answer == "":
        abort = True
        break
    if answer !=a * b:
        print("Wrong!")
        wrong += 1
    if abort == True:
        print("Noob")
            return
if wrong == 0:
    print("Good")

else:
    print("Hale" ,wrong)

Answer 1

有两个错误，返回不在函数中，vigu变量在该点没有值，你永远不会到达

如果abort == True：打印（＆＃34;菜鸟＆＃34）返回

因为在此之前你设置abort = True然后你休息一下，

Answer 2

稍微纠正了您的代码：

缩进代码;这非常重要
您不能在函数外使用“return”语句
如果要将其与“a * b”进行比较或将a * b转换为字符串

以下是我所做的修正：

import random

n = int(input("How many exercises?"))
wrong = 0
abort = False
for k in range(n):
    a = random.randint(2, 13)
    b = random.randint(2, 13)
    help = str(k+1) + ". " + str(a) + " * " + str(b)
    answer = input(help + "=> ")
    if answer == "":
      abort = True
      break
    if answer != str(a * b):
      print("Wrong!")
      wrong += 1
    if abort == True:
      print("Noob")
if wrong == 0:
    print("Good")

'''Don't know what you wanted to do here
else:
  print("Hale" ,vigu)'''

我的Python程序中的错误在哪里？
