私が持っているもの

import random

listofLetters =['k', 'i', 'n', 'g']
x = random.choice(listofLetters)
print x 

listDash = []

print "Welcome to Gues the Letter Game!"
print " "
print "=" * 5 + "Start of Game" + "=" * 5 
print ['_', '_', '_', '_', '_']
print " "

maxLife = 4

print "*" * 3 + "Life Line" + "*" * 3
print "-+" * maxLife
print "$|" * maxLife
print "-+" * maxLife
print " " 


guess = raw_input("Enter your guess: ")
howmanyletter = len(guess)

if guess == x:

    print "*" * 3 + "Life Line" + "*" * 3
    print "-+" * maxLife
    print "$|" * maxLife
    print "-+" * maxLife

else:
    print "Incorrect Guess []

[]をゲスに置き換えたい

例えば[k]
