constructors python

Question

why do you write 'self' in the argument at a function that prints the data?
like this function:

def printInfo (self):
print ("name: " + self.name + " , age: " + str(self.age))

why is that neccesary here?
is 'self' like 'this' in java?

Answer 2

Thats in OOP. "self" refers to an instance of a class.

class Car:
def __init__(self, make, model, year):
self.make = make
self.model = model
self.year = year

my_car = Car('Ford', 'F150', '1973')

print(my_car.model)
#F150

Answer 4

Slick what do you mean "instance of a class"?

Answer 5

If we think of a class as a blueprint of an object, then we think of the instance of the class as the actual object!

Each Car object thats created is an instance of the Car class
