Python Word Jumble Game Can the following complete program be improved? I have been using the Python For Absolute Beginners book and recently made my own version of the Python Word Jumble game. 

The Areas I am particularly interested in improving:


The while word Loop Block
Python Standards
Simplifying the overall program  
Commenting


# Word Jumble Game. Using Mac0S (Latest). Python V 3.4.3

import random

# Initialize Variables
WORD = ('python', 'programming', 'mug', 'glass','phone') # Constant Variable
word = random.choice(WORD) 
correct = word
jumble = ''
guess = ''

print('\t\tWelcome to Word Jumble!')
print('\n') 
print('\tUnscramble the letters to make a word.')

while word:
    position = random.randrange(len(word))
    jumble += word[position] # Jumble process 1
    word = word[:position] + word[(position + 1):] #Jumble process 2

print('\n')
print('The Jumble is:', jumble)

guess = input('Your Guess: ')
while guess != correct:
    print('Sorry, that\'s not it')
    guess = input('Your Guess: ')

if guess == correct:
    print('\n')
    print('That\'s it! You guessed it!')
    print('\n')
    print('Thanks for playing')

exit() # User has the correct answer
In general this codes looks pretty good.  A couple of nits.
The Python Library is Huge:
I would suggest replacing the while word: loop block:
while word:
    position = random.randrange(len(word))
    jumble += word[position] # Jumble process 1
    word = word[:position] + word[(position + 1):] #Jumble process 2

With a library call like:
jumble = ''.join(random.sample(word, k=len(word)))

Main loop:
By using a break inside the main loop, it can be restructured to remove some extra code like:
while True:
    print('\nThe Jumble is:', jumble)
    guess = input('Your Guess: ')
    if guess == word:
        print(&quot;\nThat's it! You guessed it!\n&quot;)
        print('Thanks for playing')
        break
    
    print(&quot;Sorry, that's not it&quot;)

This removes an extra comparison and input()
Comments:
I am not a fan of right hand style comments.  I generally prefer a needed comment to proceed the line/block it is commenting.  You used reasonably descriptive variable names, I don't know that anything other than the header comment is providing much value.
