If I pick three letters at random, what are the chances I spell an English word?
It took an unfortunate amount of time getting the PyEnchant spellchecking library to install properly, but soon after I had a neat Python script designed to look up three letter words.
import enchant import string alphabet = string.lowercase en = enchant.Dict("en_US") w,t = 0,0 for a in alphabet: for b in alphabet: for c in alphabet: t = t+1 if en.check(a+b+c): w = w+1 print w,t,float(w)/t
The script found 783 three-letter words out of 17,756 possible three-letter arrangements. That’s about 4.5%!
It was a simple matter to modify the script for four-letter words. Only about 0.6% of 456,976 four-letter arrangements are words in American English.
