Examples of how to use modules

# The area of a circle
def area(radius):
  import math                          # Not strictly necessary, because math is imported automatically
  return math.pi * radius ** 2   # Pi r squared

# Deal a hand of n cards
def dealHand(n):
  import random          # Import the functions from module random
  deck = range(1, 53)   # A fresh deck is cards 1..52 (where 1..13 are spades, etc.)
  random.shuffle(deck) # Shuffle the deck. I.e. randomize order of list elements
  return deck[0 : n]       # Return the first n of the shuffled deck

# Roll n (six-sided) dice
def rollDice(n):
  import random                                     # Import the functions from module random
  total = 0                                               # The total of the n dice
  for die in range(n):                                # Roll each die
    roll = int((random.random() * 6) + 1)  # The roll is between 1 and n inclusive but must be integer
    total = total + roll                               # Add this roll to the previous ones
  return total

# What day is it?
def todaysDay():
  import time              # Import the functions from module time
  now = time.ctime()   # Get the current time and date in string format
  return now[0:3]        # Day is the first three letters of the date string

# What year is it?
def thisYear():
  import time              # Import the functions from module time
  now = time.ctime()   # Get the current time and date in string format
  return now[-4:]         # Find last four digits. That's the year
