To access attributes or call methods on an object we use a dot-notation., the variable followed by dot and the attribute or the method name.

Syntax: the dot-notation

# Accessing an attribute
object.attribute

# Calling a method
object.method()

Example: simplified computer object

class Computer:
    # __init__ is a special method (a constructor)
    def __init__(self, brand, model):
        # attributes
        self.brand = brand 
        self.model = model
    
    # methods
    def powerOn(self):
        print(f"Powering on {self.brand} {self.model}")
  
    def powerOff(self):
        print(f"Powering off {self.brand} {self.model}")
      
c1 = Computer("HP", "OMEN")
c2 = Computer("Dell", "XPS")

# Test code
print(c2.brand + " " + c2.model)
c1.powerOn()

# Output
Dell XPS
Powering on HP OMEN
