Difference class and object

Question

What's the difference between class and object? And how we can define attribute and variables base on them?

Answer 1

Sa Ta

start_engine(self) is a method, a function is outside of a class,

Yes, a method can have any amount of values they are called arguments when defining the function and parameters when calling the function, for example

def greet(Type, Name):
# type and Name are called arguments
print(Type + Name)

# here they are called parameters
greet('Hello', 'Sa Ta')

Other than that it's correct

Answer 2

An object is an instance of a class

That means for example

Class A: # a class
def __init__(self, value): # a method
self.Value = value # an attribute for the instance

O = A(5) # value = 5

Here the Object O is an instance of the class A

Defining attributes is just like variables (attributes are class variable) but in a class for example

Class A:
attribute = 5 # can be any name

print(A.attribute) # outputs 5

Answer 3

Thanks a lot
So Are my comments in below code correct?
class Car: # a class
wheels = 4 # attribute
def __init__ (self, color): # a method, can we have more values here?
self.color = color # an attribute
self.running = False # another attribute
def start_engine(self): # a function?
self.running = true #attribute
print("Vroom!)

my_car = Car("red) #object?
print(my_car.color)
