error shown

My code is here

这是我的代码

    class Person:
    apples = 0
    ideas = 0

johanna = Person()
johanna.apples = 1
johanna.ideas = 1

martin = Person()
martin.apples = 2
martin.ideas = 1

def exchange_apples(you, me):
  #"you" and "me" will exchange ALL our apples with one another
you.apples,me.apples=martin.apples,johanna.apples
  return you.apples, me.apples

 def exchange_ideas(you, me):
  #"you" and "me" will share our ideas with one another

  you.ideas = martin.ideas+johanna.ideas
  me.ideas =you.ideas
  return you.ideas, me.ideas

exchange_apples(johanna, martin)
print("Johanna has {} apples and Martin has {} apples".format(johanna.apples, martin.apples))
exchange_ideas(johanna, martin)
print("Johanna has {} ideas and Martin has {} ideas".format(johanna.ideas, martin.ideas))

我按照他们所说的交换了值，但仍然出现错误，如图 2 所示

Answer 1

您收到错误是因为您没有正确解决问题，在这种情况下，您没有按照给定问题中的描述正确地交换苹果和想法，

这是正确的代码，

class Person:
    apples = 0
    ideas = 0

johanna = Person()
johanna.apples = 1
johanna.ideas = 1

martin = Person()
martin.apples = 2
martin.ideas = 1

def exchange_apples(you, me):
  #"you" and "me" will exchange ALL our apples with one another
    temp = you.apples
    you.apples = me.apples
    me.apples = temp

    return you.apples, me.apples

def exchange_ideas(you, me):
    #"you" and "me" will share our ideas with one another
    temp = you.ideas
    you.ideas += me.ideas
    me.ideas += temp

    return you.ideas, me.ideas

exchange_apples(johanna, martin)

print("Johanna has {} apples and Martin has {} apples".format(johanna.apples, martin.apples))

exchange_ideas(johanna, martin)

print("Johanna has {} ideas and Martin has {} ideas".format(johanna.ideas, martin.ideas))

希望这对您有帮助!
