  print("Cheerio then.")#when the function say_bye() is called, the computer would run this line of code which is printing "Cheerio then." on the console.


offer_drink()#Calling the function offer_drink, which will run the code inside the function. The computer will print "Would you care for a spot of tea?" on the console.
say_hi()#Calling the function say_hi, which will run the code inside the function. The computer will print "Why hello there!" on the console.
offer_food()#Calling the function offer_food, which will run the code inside the function. The computer will print "Biscuit".

# Example code 2

# Example Code 3
def location(country): #defining the function location with a parameter of country
  print("I am from " + country) #When the function is called the output will be "I am from" + the value of the parameter country


location("Brazil") # the parameter of Brazil so the output will be "I am from Brazil"
