UUID for Python 3

gistfile1.py

# Simple UUID class for python. Doesn't currently create random UUIDs.
# Supports conversion between byte, octal, integer, hexadecimal, RFC formatted,
#     base64 (with or w/o padding), base85, and ascii85 representations.
# Supports various math and boolean operations as if it were an integer.
