I am trying to follow this code I am reading in a book. First I will show you the code as the book has it. This is for a word jumble program. This algorythm I am refering to jumbles a word
[php]
import random



# create a sequence of words to choose from

WORDS = ("python", "jumble", "easy", "difficult", "answer", "xylophone")

# pick one word randomly from the sequence

word = random.choice(WORDS)

# create a variable to use later to see if the guess is correct

correct = word



# create a jumbled version of the word

jumble =""

while word:

position = random.randrange(len(word))

jumble += word[position]

word = word[:position] + word[(position + 1):][/php]

here is where I am a little unsure. is the statement
[php]
while word:[/php]
the same as
[php]while word != "":[/php]

assuming the above two statments are the same. I am haveing trouble seeing why the variable word will ever evaluate to an emptly set. It seems like the while loop would concatenate forever, building a large and larger word. Any help in understanding this would be appreciated :-)
