More Words From Hex Letters (with extra zero's)

STOP PRESS! Someone commented that zeros could be used as ones so an update is at the bottom.

It was pointed out to me that I needn't restrict myself to four character words, and could use the number '1' as letter 'l', and the number '5' as the letter 'S'.

So here is the program and output of words of four or more characters that can be made from hexadecimal characters.

import urllib

words = urllib.urlopen(''
#len(words) == 25104

def findwords(hexchars):
hexchars = set(hexchars)
hexwords = [w for w in words if 4 <= len(w) and all(ch in hexchars for ch in w)]
return hexwords

def printwords(hexwords):
for i in range(0, len(hexwords), 5):
print (' ' + ' '.join("%-8s" % w for w in hexwords[i:i+5]))

hexchars = 'abcdef'
#hexwords = findwords(hexchars)
#print "\nHEXWORDS"

# Now to use one: 1 as ell: l; and five: 5 as ess: s
hexwords = findwords(hexchars + 'ls')
hexwords = [word.replace('s','5').replace('l','1') for word in hexwords]
print "\nHEXWORDS USING one: 1 AS ell: l; AND five: 5 AS ess: s"

The list of words found have some gems, such as babble, for when you know your generating data that no one will read; baffle, baseball, blab, bleed, bless, (and blessed if it were in the dictionary), cabal, cascade, cease, debacle, decade, decease, (and should have deceased), false, flee, label, ...

(Someone at work suggested we use 1abe1 or label to prefix a section of writes to a peripheral in an assembler prog which got me going).

The words:

HEXWORDS USING one: 1 AS ell: l; AND five: 5 AS ess: s
aaa5 ababa aba5e abba5 abbe

Additional Words with an 'o'

Without Michaels comment I would have skipped all words that use zero for an o, so I made the following two changes:

hexwords = findwords(hexchars + 'lso')
hexwords = [word.replace('s','5').replace('l','1').replace('o', '0') for word in hexwords]

And created the following extra words:

  ab0de    acc01ade ad0be    a1c0a    a110cab1e
a10e a100f a150 ba1b0a ba550
b10b b10c b100d b0bb1e b0ca
b0de b01d b01dface b01e b010
b05e b055 caca0 c10d c105e

  1. NOOOOoooooohhhhhh......

    (But Ta)

  2. $ grep -i "^[abcdeflso]*$" /usr/share/dict/words | tr slo 510 | column

    ... just saying :)

  3. (and if you are picky, then replace "grep" with "egrep" and "*" with "{4,}" in the regexp to get only 4+ character words)

    Your dictionary is missing "bobsledded". How unfortunate... as it is quite a long word :)

  4. Andy,
    I can't hate you 'cos at least you used Unix commands :-)

    More power to your Unix-friendly elbow!

  5. Some people stretch things even further, with 0 --> o; 1 --> L or sometimes 1 --> i; 2 --> Z; 3 --> e; 4 --> y; 5 --> s; 6 --> b; 7 --> t; 8 --> B; 9 --> g.
    "For example, leet spellings of the word leet include 1337" -- Wikipedia: leet.

  6. Hi anon. Unfortunately we have to have a dictionary and the one chosen does not contain your two words.
