# 13 function

# 13.1 write a function to print your name in capital letters.

Def printName ():

Print ("CCCC A RRRRR TTTTTTT EEEEEE RRRRR")

Print ("C C An A R R T E R R")

Print ("C An A R R T EEEEEE R R")

Print ("C AAAAAAAAA RRRRRR T E RRRRRR")

Print ("C CA A R R T E R R")

Print ("CCCC An AR R T EEEEEE R R")

Print ()

For i in range (5):

PrintName () # if you add print (printName ()), the none value will appear.

# 13.2 create a function that can print names, addresses, streets, cities, states, provinces, zip codes and countries all over the world

Def printAdress (name,address,street,city,code,country):

Def calculateTax (price,tax_rate):

Total = price + (price * tax_rate)

Global my_price

My_price = 1000

Print ("my_price (inside function) =", my_price)

Return total

My_price = float (input ("Enter a price:"))

TotalPrice = calculateTax (my_price,0.06)

Print ("price =", my_price, "Total price =", totalPrice)

Print ("my_price (outside function) =", my_price)
