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!

class ClassName(object): #"(object)" isn't mandatory unless this class inherit from another
  	def __init__(self, var1=0, var2):
    
    	#the name of the construct must be "__init__" or it won't work
    	#the arguments "self" is mandatory but you can add more if you want 
    	self.age = var1
    	self.name = var2
    
    	#the construct will be execute when you declare an instance of this class
    
  	def otherFunction(self):
    	
        #the other one work like any basic fonction but in every methods,
    	#the first argument (here "self") return to the class in which you are
 	

class car():
  gas=100
  def __init__(self, mpg, position, gast):
    gas=gast
    self.mpg=mpg
    self.position=position
  def move(self, miles):
    if (self.mpg*gas>miles):
      print("You don't have enough gas")
    elif(self.mpg*gas<=miles):
      self.position+=miles
      gas-=(1/self.mpg)*miles
  def get_gas(self):
    	if(self.position %50==0):
        	gas=100
        else:
          	print("You can't do that")
class Truck(car):
  def __init__(self, carry_capacity):
    	self.carry_capactiy=carrycapacity
  def carry(self, load):
    	if(load<=carry_capacity):
        	print("Successfully carried")
        else:
          	print("Failed to carry")
Car=car(5, 0, 100)
Car.move(50)
Car.get_gas()
truck=Truck(5)
truck.get_gas()
truck.carry()

      
 

class person:
    name = "jake"
    age = 13
x = vars(person)
print(x)

class a_class:
  #This initalizes the object, and is executed when you define
  #a new object in the class
  def __init__(self, input1):
    self.__input1 = input1
    
  #This is a function of the object that can be called
  def return_input(self):
    return self.__input1
  
a_class_object = a_class("input string")
print(a_class_object.return_input())
