Creating new instances of class objects can be a great way to keep track of values using attributes associated with the object. The values of these attributes can be easily changed at the object level. The following code illustrates a famous quote by George Bernard Shaw, using objects to represent people. Fill in the blanks to make the code satisfy the behavior described in the quote. # "If you have an apple and I have an apple and we exchange these apples then
# you and I will still each have one apple. But if you have an idea and I have
# an idea and we exchange these ideas, then each of us will have two ideas."
# George Bernard Shaw
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):
#Here, despite G. B. Shaw's quote, our characters have started with
#different amounts of apples so we can better observe the results.
#We're going to have Martin and Johanna exchange ALL their apples with #one another.
#Hint: how would you switch values of variables,
#so that "you" and "me" will exchange ALL their apples with one another?
#Do you need a temporary variable to store one of the values?
#You may need more than one line of code to do that, which is OK.
Temp = you. apples
you. appples = 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.
#What operations need to be performed, so that each object receives
#the shared number of ideas?
#Hint: how would you assign the total number of ideas to
#each idea attribute? Do you need a temporary variable to store
#the sum of ideas, or can you find another way?
#Use as many lines of code as you need here.
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))
Johanna has 1 apples and Martin has 1 apples
Johanna has 2 ideas and Martin has 2 ideas
below is an error:
Not quite. Did you properly add or equivalate the attributes
of both instances of the Person() class?
Can you help me why is and show step by step in python crash course
