Question 1 Select all the choices producing a
string which contains multiple lines?
Examples of each of the choices are presented below.
#---------Option A---------------
s = ("Line 1","Line 2")
#---------Option B---------------
s = """Line 1
Line 2"""
#---------Option C---------------
s = "Line 1\nLine 2"
#---------Option D---------------
s = "Line 1" + "Line 2" #Option D
Make your statements look the same as the
examples.

. Write a Scheme program for each of the following.
Which takes in two lists “lst1” and “lst2”, both of which are
individually sorted (in ascending order), and returns a list
containing the elements of both lst1 and lst2 in sorted order.
Print the final list. Input to the program are “lst1” and “lst2”.
For instance,
lst1 = (1 3 5 7) and lst2 = (2 4 6 8)
output: (1 2 3 4 5 6 7 8)

Adjust the following code so the two errors below are
non-present:
1. __init__() : Since Pizza object don't have it's own set()
datastructure, the toppings in the pizza object are manimupated
from out of the object. (-1.0)
2. __eq__() : How about "self.toppings == other.toppings" rather
than "self.toppings - other.toppin == set())".
Code:

self.toppings = top

Here is my question.
In clock.py, define class Clock which will perform some simple
time operations. Write an initializer function for Clock that will
take three arguments from the user representing hour (in 24-hour
format), minutes, and seconds. Each of these parameters should have
a reasonable default value. You should check that the provided
values are within the legal bounds for what they represent and
raise a ValueError if they are not.
if error_condition:
raise ValueError("Descriptive error message")...

Which of the following statements (a-d) are true if the following lines of code are executed? int G = 17; int &H = G; A. H is now an alternate name for G B. Adding 1 to H will change the value of G to 18 C. Subtracting 5 from G and printing H will display the value 12 D. The condition H == G will give a true result E. All of the statements (a-d) are true...

***IN PYTHON 2.7****Augment the following code with a new class
named 'Coin'. Coin should inherit from Die, with the following
modifications;
The constructor should not take any arguments; a coin always
has two sides
add a flip() method that uses the roll() method from the parent
class. If roll returns 1; flip should return "HEADS". If roll
returns a 2, flip should return "TAILS"
Do not override the roll or rollMultiple methods from the
parent class
