Letter Guessing Game In Python

I'm attempting to code a basic letter game in python. In the game, the computer moderator picks a word out of a list of possible words. Each player (computer AI and human) is shown

Solution 1:

Number of characters in the word: len() function

In [15]: len('jabberwocky')
Out[15]: 11

An example of a mask:

In [16]: mask = ' '.join(('_' for i in range(len('jabberwocky'))))

In [18]: mask
Out[18]: '_ _ _ _ _ _ _ _ _ _ _'
#         j a b b e r w o c k y

References on everything involved in the mask example:

1. str.join() method.
2. range() built-in function.
3. generator expressions (used to generate N underscores).

All in all, what it does is:

1. Count the characters in the word 'jabberwocky'
2. Generate n underscores
3. Join them by a space.

Solution 2:

On a cursory analysis of your project, I believe you can find all the answers you need in the Python documentation. Addressing your first question, see here:

http://docs.python.org/3.2/library/functions.html#len

Addressing future questions that you may have as you need to deal with strings, see here: http://docs.python.org/3.2/tutorial/introduction.html#strings
