Review prerequisite knowledge
10

11. www.glcnetworks.com
Basic stuffs
● Variable
● Command (keywords)
● Operation (+, -, *, /, %)
● Array (list, tuple, dictionary)
● Loop
○ For loop
○ While loop
11
x = "Python is "
y = "awesome"
z = x + y
print(z)
fruits = ["apple", "banana", "cherry"]
for x in fruits:
print(x)

12. www.glcnetworks.com
Procedural Python
● Code executed sequentially
● Easy to understand
● Faster to implement
● Natural
● Program lines can be very long
● Need a way to architect to:
○ Manage our code physically
○ Manage our application logic
12
x = "Python is "
y = "awesome"
z = x + y
print(z)
fruits = ["apple", "banana", "cherry"]
for x in fruits:
print(x)

Efficient code: using functions
● A function is a block of code which
only runs when it is called.
● You can pass data, known as
parameters, into a function.
● A function can return data as a
result.
13
def my_function(fname, lname):
print(fname + " " + lname)
my_function("Emil", "Refsnes")

14. www.glcnetworks.com
Efficient code: using external functions (library)
● Consider a module to be the same
as a code library.
● A file containing a set of functions
you want to include in your
application.
14
vim mymodule.py
person1 = {
"name": "John",
"age": 36,
"country": "Norway"
}
vim myapp.py
import mymodule
a = mymodule.person1["age"]
print(a)

We need more features...
● Grouping variables / functions -> so that it can represent real object
● Define access to variables/functions
● Easily extend current functions/group to have more features without losing
connections to current functions/group

OOP in python

17. www.glcnetworks.com
Class vs object
● Almost everything in Python is an
object, with its properties and
methods.
● A Class is like an object
constructor, or a "blueprint" for
creating objects.
17
class MyClass:
x = 5
p1 = MyClass()
print(p1.x)
Source: www.w3schools.com

18. www.glcnetworks.com
The __init__() Function
● The __init__() function is called
automatically every time the class
is being used to create a new
object.
● Use the __init__() function to
assign values to object properties,
or other operations that are
necessary to do when the object is
being created
18
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
p1 = Person("John", 36)
print(p1.name)
print(p1.age)
Source: www.w3schools.com

19. www.glcnetworks.com
Method
● Objects can also contain methods
● Methods in objects are functions
that belong to the object.
19
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
def myfunc(self):
print("my name is " + self.name)
p1 = Person("John", 36)
p1.myfunc()

20. www.glcnetworks.com
The self Parameter
● The self parameter is a reference
to the current instance of the class,
and is used to access variables
that belongs to the class.
● It does not have to be named self ,
you can call it whatever you like,
but it has to be the first parameter
of any function in the class:
20
class Person:
def __init__(mysillyobject, name, age):
mysillyobject.name = name
mysillyobject.age = age
def myfunc(abc):
print("Hello my name is " + abc.name)
p1 = Person("John", 36)
p1.myfunc()
Source: www.w3schools.com

21. www.glcnetworks.com
Modify Object Properties
● After a class instance is created
(aka. object), its possible to modify
the object
21
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
def myfunc(self):
print("Hello my name is " + self.name)
p1 = Person("John", 36)
p1.age = 40
print(p1.age)
Source: www.w3schools.com

22. www.glcnetworks.com
Delete Object Properties
● To delete a property of an object
use del command
22
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
def myfunc(self):
print("Hello my name is " + self.name)
p1 = Person("John", 36)
del p1.age
print(p1.age)
Source: www.w3schools.com

23. www.glcnetworks.com
Delete Object
● To delete a created object use del
command
23
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
def myfunc(self):
print("Hello my name is " + self.name)
p1 = Person("John", 36)
del p1
print(p1.age)
Source: www.w3schools.com

24. www.glcnetworks.com
The pass Statement
● Class definitions cannot be empty
● If a class has no content, use pass
statement to avoid getting an error
24
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
pass
x = Student("Mike", "Olsen")
x.printname()
Source: www.w3schools.com

Inheritance
● Inheritance allows us to define a
class that inherits all the methods
and properties from another class.
● Parent class is the class being
inherited from, also called base
class.
● Child class is the class that inherits
from another class, also called
derived class.
25
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
pass
x = Student("Mike", "Olsen")
x.printname()
Source: www.w3schools.com

26. www.glcnetworks.com
__init__() function at child
● When you add the __init__()
function, the child class will no
longer inherit the parent's __init__()
function.
● The child's __init__() function
overrides the inheritance of the
parent's __init__() function.
● To keep the inheritance of the
parent's __init__() function, add a
call to the parent's __init__()
function
26
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname):
Person.__init__(self, fname, lname)
x = Student("Mike", "Olsen")
x.printname()
Source: www.w3schools.com

27. www.glcnetworks.com
the super() Function
● By using the super() function, you
do not have to use the name of the
parent element, it will automatically
inherit the methods and properties
from its parent.
● super() function will make the child
class inherit all the methods and
properties from its parent
27
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname):
super().__init__(fname, lname)
x = Student("Mike", "Olsen")
x.printname()
Source: www.w3schools.com

28. www.glcnetworks.com
the super() Function (2)
● Adding methods and properties
28
class Person:
def __init__(self, fname, lname):
self.firstname = fname
self.lastname = lname
def printname(self):
print(self.firstname, self.lastname)
class Student(Person):
def __init__(self, fname, lname, year):
super().__init__(fname, lname)
self.graduationyear = year
def welcome(self):
print("Welcome", self.firstname,
self.lastname, "to the class of",
self.graduationyear)
x = Student("Mike", "Olsen", 2019)
x.printname()
x.welcome()
