Question
In: Computer Science
For python... class car: def __init__(self) self.tire self.gas def truck(self,color) &nb
For python...
class car:
def __init__(self)
self.tire
self.gas
def truck(self,color)
style = color
return
def plane(self,oil)
liquid = self.oil + self.truck(color)
For the plane method, I am getting an error that the class does not define __add__ inside init so I cannot use the + operator. How do I go about this.

Expert Solution
The error you were getting because self.truck(color) returns Empty object and you need to define how you want to addd objects to support the "+" operation. The correct code intuitievly would be
Code-
class car:
#initialized the new car with tire and gas
values
def __init__(self):
self.tire=0
self.gas=0
#Assign color to the object in style attribute
def truck(self,color):
self.style = color
return self.style
#update gas attribute of object using the plane
method
def plane(self,oil):
liquid = self.gas+oil
self.gas=liquid
return liquid
x=car()
print("Initially gas= ",x.gas," tire= ",x.tire)
x.truck("yellow")
print("Executing truck method gas= ",x.gas," tire= ",x.tire,"
style= ",x.style)
x.plane(100)
print("Executing plane method gas= ",x.gas," tire= ",x.tire,"
style= ",x.style)

Add class “getter” methods to return the values for model, color,
and MPG
Add class “setter” methods to change the existing values for model,
color, and MPG. The value to be used in the methods will be passed
as an input argument.
Add class method that will calculate...

How would I setup this dictionary for Python 3?
class Student(object):
def __init__(self, id, firstName, lastName, courses = None):
The “id”, “firstName” and “lastName” parameters are to be
directly assigned to member variables (ie: self.id = id)
The “courses” parameter is handled differently. If it is None,
assign dict() to self.courses, otherwise assign courses directly to
the member variable.
Note: The “courses” dictionary contains key/value pairs where
the key is a string that is the course number (like “course1”) and...

Inheritance - Method Calls
Consider the following class definitions.
class C1():

return 2*self.g()
def g(self):

obj3 = C3()

For this problem you are to consider which methods are called
when the f method is called. Because the classes form part of an
inheritance hierarchy, working out what happens will...
