Example Objects within single file in Python

objects-classes-in-python.py

# This is an example of using Object/Classes in Python.
# The code has been tested with Python 2.7.

# My Car Object
class ExampleCarObject:
  # This is the constructor so when creating the object, these are
  # the required parameters. "self" is needed as the first parameter
  # for all functions in the object but when call it, you do NOT
  # pass anything in. At the bottom there is an example.
  def __init__(self, carOwner):
    # Uses the parameter carOwner to set the owner within this example
    self.owner = carOwner
    # The color of the car is blank for now
    self.color = ''

  # Can retrieve objects
  # Example. c.getCarOwner()
  def getCarOwner(self):
    return self.owner

  # Can also create addition functions (setters)
  def setCarColor(self, color):
    self.color = color

  def getCarColor(self):
    return self.color

  def printCarInfo(self):
    if self.color != '':
      print (self.owner + ' owns a ' + self.color + ' car.')
    else:
      print (self.owner + ' owns a car.')



# Car 1 has a owner named john. This is an example of calling
# the constructor (__init__)
car1 = ExampleCarObject('John')
print ('Car 1 is owned by ' + car1.getCarOwner())
# Set the car color
car1.setCarColor('blue')
print ('And there car is ' + car1.getCarColor())

# Output so far is:
# Car 1 is owned by John
# And there car is blue


# Create second object
car2 = ExampleCarObject('Jane')

# Print info about both cars
car1.printCarInfo()
car2.printCarInfo()

# Additional output is:
# John owns a blue car.
# Jane owns a car.
