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

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges"what's being bought" are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them"for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s . so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of events"s of length m and s of length n, each possibly containing an event more than once"and decides in time o(m + n) whether s is a subsequence of s.
