Python Python Basics (2015) Letter Game App Letter Game Introduction

1,000 Points

So confused

I start the script and when I press any letter it prints forever

import random

# make a list of words
words = [

while True:
    start = input("""Press enter/return to start, or Q to quit:
>> """)
    if start.lower == 'q':
    # pick a random word
    secret_word = random.choice(words)
    bad_guesses = []
    good_guesses = []

    while len(bad_guesses) < 7 and len(good_guesses) != len(list(secret_word)):
        # draw spaces

        # draw guessed letters and stricks
        for letter in secret_word:
            if letter in good_guesses:
                print(letter, end='')
                print('_', end='')

        print('Strikes: {}/7'.format(len(bad_guesses)))
    # take guess

    #print out win/lose

[MOD: added ```python formatting -cf]

Currently, the second while statement has no exit. Add more code to ask for guesses thus the bad_guesses will break out of the loop eventually.

This is the danger of coding while loops: make sure the the loop exit code is understood or programmed first.

Post back if you have more questions. Good Luck!!!

It's not necessarily a literal "exit". Rather, it is either a break statement or something that will eventually cause the while conditions to fail.

In extreme debug situations, due to code that has a lot of code yet to be implemented, I'll add counter to limit the while loops. A sort of "override". Once the code is working the override safety breakout can be removed.

A simple way to add this:

# before while loop
count = 10  # some limit

# while loop
while conditions and count > 0 # count is positive 
    count -= 1  # decrement count
