A friend of mine, who used Java in his day job, sent me a code snippet that he needed help with. He was new to Python and was still getting used to the differences between Java and Python. He mostly worked with databases, so he was exploring the different ORMs that were available. He tried SQLAlchemy, the Django ORM, and eventually, found that he liked a still very new ORM called Pony. At that time, the documentation for Pony was still in its infancy, so he sent me the code so that I could help him out. It looked similar to this:

def gen():
    return random.choice(consonants) + random.choice(vowels)


names = [(gen() for _ in range(random.randint(3, 4))) for i...
