INSTALL

https://pypi.org/project/leximited/1.1.1/

pip install leximited

IMPORT

import leximited

USE

Call leximited.to_leximited() with numbers (int or str) or arbitrary strings to get their leximited version.

Call leximited.from_leximited() with lex-encoded numbers (int or str) or arbitrary lex-encoded strings to get their "normal" version.

Also supports lists and tuples and allows for mixed lists with lex-encoding on numbers only, see examples below.

print(f'INTEGERS: {leximited.to_leximited(1)}')
INTEGERS: 11

print(f"NUMBERS WITH LEADING 0s: {leximited.to_leximited('002')}")
NUMBERS WITH LEADING 0s: '12'

print(f'BIG NUMBERS: {leximited.to_leximited(2000000000)}')
BIG NUMBERS: 92102000000000

print(f"SHORT STRINGS: {leximited.to_leximited('Bh3!!!')}")
SHORT STRINGS: 6Bh3!!!

print(f'LONG STRINGS: {leximited.to_leximited("a man, a plan, a guy: eleets")}')
LONG STRINGS: 9228a man, a plan, a guy: eleets

print(f"EMPTY STRINGS: {leximited.to_leximited('')}")
EMPTY STRINGS: 0

Also takes lists or tuples, and optionally preserve non-number strings as their original form (convert_text defaults to True to lex-encode everything).

in_list = [1, '002', 2000000000, 'Bh3!!!', 'a man, a plan, a guy: eleets', '']
print(f'INPUT: {in_list}')
leximited_list = leximited.list_to_leximited(in_list, convert_text=True)
print(f'LEXIMITED: {leximited_list}')
back_again = leximited.list_from_leximited(leximited_list)
print(f'AND BACK AGAIN: {back_again}')

INPUT: [1, '002', 2000000000, 'Bh3!!!', 'a man, a plan, a guy: eleets', '']
LEXIMITED: [11, '12', 92102000000000, '6Bh3!!!', '9228a man, a plan, a guy: eleets', '0']
AND BACK AGAIN: [1, '2', 2000000000, 'Bh3!!!', 'a man, a plan, a guy: eleets', '']

Note that the leading zeros are lost when converting back again.
