# Classes and Objects

## Classes:

* Uses the keyword `class`
* To leave for later you use the `pass` keyword

```python
class Vehicle:
	pass
```

* How a class template should look like:

```python
class Vehicle:
	def __init__(self, body_type, make):
		vehicle_body = body_type
		vehicle_make = make
		
# Initiallizing the class:
car1 = Vehicle("jeep", "toyota")

print(car1.vehicle_body)
```

The above code will fail to print as the object `car1` does not have a `vehicle_body` attribute. **That is where the `self` argument comes in. If you modify the variables assigned with `self.` before it will initialize itself and you will have access to the varios items in the class**

```python
class Vehicle:
	def __init__(self, body_type, make):
		self.vehicle_body = body_type # Using self
		self.vehicle_make = make      # To reference itself
                                      # For other objects
# Initiallizing the class:
car1 = Vehicle("jeep", "toyota")
car2 = Vehicle("truck", "mercedes")

# Prints jeep
print(car1.vehicle_body)
# prints mercedes
print(car2.vehicle_body)
```

**The `self` keyword is used to reference itself**

* Technically car1 and car2 are variables but they are pointing to an object in memory
