'''

object-oriented programming in Python— an optional but powerful feature

of the language that cuts development time by supporting programming by customization

'''

# classes define new types

# of objects that extend the core set

class Worker:

def __init__(self, name, pay): # Initialize when created

self.name = name # self is the new object

self.pay = pay

def lastName(self):

return self.name.split()[-1] # Split string on blanks

def giveRaise(self, percent):

self.pay *= (1.0 + percent) # Update pay in place

bimri = Worker('Bimri Kintu', 500000) # Make two instances

unity = Worker('Unity Techi', 300000) # Each has name and pay attrs

print(bimri.lastName()) # call method: bimri is self

print(unity.lastName())

unity.giveRaise(.10) # Updates unity's pay

bimri.giveRaise(.1)

print(unity.pay)

print(bimri.pay)
