class methods in python code example
Example 1: static class python
#To create a static method, just add "@staticmethod" before defining it.
>>>class Calculator:
# create static method
@staticmethod
def multiplyNums(x, y):
return x * y
>>>print('Product:', Calculator.multiplyNums(15, 110))
Product:1650
Example 2: 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!
Example 3: python define class
class uneclasse():
def __init__(self):
pass
def something(self):
pass
xx = uneclasse()
xx.something()
Example 4: python classes
class Box(object): #(object) ending not required
def __init__(self, color, width, height): # Constructor: These parameters will be used upon class calling(Except self)
self.color = color # self refers to global variables that can only be used throughout the class
self.width = width
self.height = height
self.area = width * height
def writeAboutBox(self): # self is almost always required for a function in a class, unless you don't want to use any of the global class variables
print(f"I'm a box with the area of {self.area}, and a color of: {self.color}!")
greenSquare = Box("green", 10, 10) #Creates new square
greenSquare.writeAboutBox() # Calls writeAboutBox function of greenSquare object
Example 5: class methods in python
from datetime import date
# random Person
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
@classmethod
def fromBirthYear(cls, name, birthYear):
return cls(name, date.today().year - birthYear)
def display(self):
print(self.name + "'s age is: " + str(self.age))
person = Person('Adam', 19)
person.display()
person1 = Person.fromBirthYear('John', 1985)
person1.display()
Example 6: class methods in python
@classmethod
def func(cls, args...)
