Assignment

Implement the functions below in the file csc401_homework2.py which can be found on in the Week 2 folder. You should save the template file I provided and then modify that file by adding the bodies for the functions. When you do, make sure to remove the placeholder pass statements that are currently there.

1. Implement the function buy_tickets(age, ticket_type) so that it returns the price of a train ticket purchase, given 2 parameters:

1.      age - the age of the purchaser

its data type is a positive integer

2.      ticket_type- type of ticket being purchased

its data type is string with 2 legal values: “monthly” and “10-ride”

For the sake of this assignment you can assume that the parameters are always valid values.

This is the algorithm for calculating a ticket price:

a.  standard 10-ride price is $38

b.  standard monthly price is $159.50

c.  If the purchaser is 65 or older, they get a 10% discount These test cases should all pass:

>>> buy_ticket(21, "10-ride") 38

>>> buy_ticket(21, "monthly") 159.5

>>> buy_ticket(70, "monthly") 143.55

>>> price = buy_ticket(70, "10-ride")

>>> price 34.2

 2.      Change the implementation of the function sequences() found in the csc401-homework2.py file so that the following three sequences are printed

      by the for loops found in sequences(). The information below shows how you would call the function and what it would display as a result:

>>> sequences()

9 10 11 12 13 14 15

4 8 12 16 20 24 28

30 27 24 21 18 15 12

 3.      Implement the function shorten_text(word_list) that takes a list of strings as a parameter and for each word in the list. prints the first character + “…” + the last character of each string, one word per line. If the list provided as a parameter is empty, the function prints a message to that effect. If any of the strings are empty, they are skipped in the display. The information below shows how you would call the function shorten_text() and what it would display for a couple of parameters:

>>> shorten_text(['house', 'business', 'trees']) h...e

b...s

t...s

>>> shorten_text([]) Input is empty

>>> shorten_text([‘horse’, ‘’, ‘candy’] h...e

c...y

 4.      Implement a function find_multiples(number_list, target) that takes as parameters a list of numbers and a numeric value. It prints out each value from number_list that is a multiple of the target number. If an empty list is
