CLASS - June 11, 2023 - SUNDAY - CLASS 7 @6PM EST

COMPLEX FUNCTIONS

- A function is a collection of code, which performs a specific task.
- You can pass data, known as parameters, into a function. 
- You’ll  want to name your functions in lowercase. E.g., write def dogs_are_cool(): instead of DEF DOGS_ARE_COOL():

DEF

- Def is a keyword used to tell python that you are creating a function
- Def has a specific format to follow in order to create a function

RETURN STATEMENT

- You can use the return statement in python functions
- Sometimes when we we call a function, we are going to want to get information back from that function 

USE CASES: IN CYBER SECURITY YOU MAY NEED TO CREATE A FUNCTION FOR FINDING ALL OPEN PORTS ON WEB SERVERS.

# LAB 1 - CREATING OUR FIRST FUNCTION

def what_car_you_drive():
    print("I drive a Tesla")

what_car_you_drive()

# LAB 2 - ANOTHER FUNCTION EXERCISE

def the():
    print("The")

print("Enter")
the()
print("Game")

# LAB 3 - SLIGHTLY MORE COMPLEX FUNCTION CODE

def make(model):
    print("Blue " + model)

make("Tesla")
make("Nissan")
make("Benz")

# LAB 4 - ANOTHER COMPLEX FUNCTION CODE

def introductions(name, height):
    print("Good Afternoon " + name + " you work in IT and you are " + height)

introductions("Edwin", "190 CM")
introductions("Jason", "185 CM")
introductions("Hannah", "120 CM")
introductions("Keisha", "570 CM")

def introductions(name, height, square):
    print("Good Afternoon " + name + " you work in IT and you are " + height + "and you are " + square + " Thanks!")

introductions("Edwin", "190 CM", "shape")
introductions("Jason", "185 CM", "shape")
introductions("Hannah", "120 CM", "shape")
introductions("Keisha", "570 CM", "shape")

# LAB 5 - USING TUPLES WITHIN A FUNCTION

Quick note:
- Using tuples within a function
- Input a* before the sole argument name in the function if you don’t know how many arguments you will work with
- Let’s lab using tuples

**********************************************************************************************************************
HERE IS THE CODE BELOW
**********************************************************************************************************************
def vehicles(*cars):
    print("The best car in the world is " + cars[2])

vehicles("Telsa", "Mercedes", "Range Rover", "Nissan", "Ferari")

# LAB 6 - ADDING NUMBERS TOGETHER USING THE RETURN STATEMENT IN OUR FUNCTION

def add():
    return 8+3+10

print(add())

# LAB 7 - MULTIPLYING NUMBERS WITH THE RETURN STATEMENT IN OUR FUNCTION

def multiply(num1, num2):
    result = num1 * num2
    return result

print(multiply(5,5))
