"""Generates a random string of alphanumeric characters of the given length.
If no length is specified, a single character is returned.
On Python 3.5, this string is pseudo-randomly generated using
:py:mod:`random`. With 3.6 and later, the randomness is generated with
:py:mod:`secrets`, making the randomization cryptographically strong.
Args:
length (:obj:`int`, optional): Desired string length. Defaults to 1.
Returns:
str: A pseudo-random alphanumeric string.
Examples:
>>> print(alphanum.generate())
'G'
>>> print(alphanum.generate(10))
'a93jfDjdA0'
