#A function is a collection of code, which performs a specific task.
def say_hi(name, age): #This defines the function you can also add
#variables in the parentheses
print("Hello " + name + ", you are " + str(age))
say_hi("Justin", 36) #This calls the function and executes the code
say_hi("Jhon", 38) #Inside the parentheses you can state the name
say_hi("Jason" , 40) #and age that you want to run
#when you are naming a function, name the function with all lowercase.
#If you have a short two word name of your function it is not necessary
#to use a underscore symbol ( _ ), however if you want to there is no
#problem.
