def generate(length=DEFAULT_LENGTH):
return '<STR_LIT>'.join(random.SystemRandom().choice(ALPHABET)<EOL>for _ in range(length))<EOL>
Generate a random string of the specified length.

The returned string is composed of an alphabet that shouldn't include any
characters that are easily mistakeable for one another (I, 1, O, 0), and
hopefully won't accidentally contain any English-language curse words.
