Guess word game

import random

#Create a list

guesslist = ['vesicle', 'lysosome', 'chloroplast', 'ribosome', 'vacuole']

chance = 3
score = 0

print (guesslist)

while chance != 0:
    random_item = random.choice(guesslist)
    user_input = input("Please guess a word: ")
    if user_input == random_item:
        print ("That's correct!")
        score = score + 100
        print ("Score:", score)
    else:
        if user_input not in guesslist:
            print ("Sorry, that isn't even in the list!")
            chance = chance - 1
            print ("Chance Remaining:", chance)
        else:
            print ("Sorry, wrong choice!")
            chance = chance - 1
            print ("Chance Remaining:", chance)

if chance == 0:
    print ("The word was", random_item)
    print ("The score is", score)

Countdown Machine
