This library is a port of fasiha/mudderjs to Python.
From the original readme:
Generate lexicographically-spaced strings between two strings from pre-defined alphabets.
Usage is nearly identical to the original:
from mudder import SymbolTable
hex_ = SymbolTable('0123456789abcdef')
hexstrings = hex_.mudder('ffff', 'fe0f', num_strings=3)
print(hexstrings)
# ['ff8', 'ff', 'fe8']
