how to make a class in python
class Person:
def __init__(self, _name, _age):
self.name = _name
self.age = _age
def sayHi(self):
print('Hello, my name is ' + self.name + ' and I am ' + self.age + ' years old!')
p1 = Person('Bob', 25)
p1.sayHi() # Prints: Hello, my name is Bob and I am 25 years old!classes in python
class Foo:
def __init__(self):
self.definition = Foo!
def hi():
# Some other code here :)
# Classes require an __init__ if you want to assign attributes. (self) defines what describes the attribs.classes in python
# Python classes
class Person():
# Class object attributes (attributes that not needed to be mentioned when creating new class of person)
alive = True
def __init__(self, name, age):
# In the __init__ method you can make attributes that will be mentioned when creating new class of person
self.name = name
self.age = age
def speak(self):
# In every method in class there will be self, and then other things (name, age, etc.)
print(f'Hello, my name is {self.name} and my age is {self.age}') # f'' is type of strings that let you use variable within the string
person_one = Person('Sam', 23) # Sam is the name attribute, and 23 is the age attribute
person_one.speak() # Prints Hello, my name is Sam and my age is 23
==================================================================
# Output:
>>> 'Hello, my name is Sam and my age is 23'why should i use classes in python
"Why should I use classes in python?"
Classes are essential in OOP.
A good reason to use classes is to make your code structured and organised.
Furthermore it is easy to import functions when they are part of a class since you can just import the class.
Classes provide methods that are useful such as the __repr__ method which allows you to represent an object by a string.
Classes allow for access control (encapsulation) by using the underscore character.Python Class Example

class Vehicle:
def __init__(self, brand, model, type):
self.brand = brand
self.model = model
self.type = type
self.gas_tank_size = 14
self.fuel_level = 0
def fuel_up(self):
self.fuel_level = self.gas_tank_size
print('Gas tank is now full.')
def drive(self):
print(f'The {self.model} is now driving.')
obj = Vehicle("Toyota", "Carola", "Car")
