>>> import random, string
>>> key = ''.join(random.choice(string.ascii_uppercase + string.ascii_lowercase + string.digits) for x in range(32))
>>> iv = ''.join(random.choice(string.ascii_uppercase + string.ascii_lowercase + string.digits) for x in range(16))

>>> print(key, len(key))
('eXS8qhYpisQf4zm60pBeMGbCTh5dfXiQ', 32)
>>> print(iv, len(iv))
