First Summer 2006

• how a simple Python program looks like
• (and compare that with Alice programs)
• how you save, compile and run Python programs
• (two ways of running a Python program will be shown).

# Guess my number.

import random 

num = random.randrange(100) + 1

print "The secret number is " + str(num)

tries = 0

while True:
  guess = int(raw_input("What is the secret number? (" + str(num) + ") "))
  if guess > num: 
    print str(tries+1) + ": Try lower."
  elif guess < num: 
    print str(tries+1) + ": Try higher."
  else: 
    print "You guessed it! In " + str(tries + 1) + " attempts."
    break
  tries += 1
  if tries >= 5: # number of tries allowed 
    print "Sorry, you lost."
    tries = 0
    num = random.randrange(100) + 1
    
raw_input("Press Enter if you liked the game.")

Interacting with it is our main goal now.

Learning how it develop it will come much later.

Once this is clear you can and should work on the two new homework assignments posted today.
