Python Raspberry Pi

Solution to NPR’s puzzle using python


Of course I’m using my Raspberry Pi. I installed a free dictionary (sudo apt-get install wamerican).

I wanted to practice python, but to not go crazy, so I cheated with some grooming with simple shell commands, e.g.,

$ egrep ‘^[a-z]{5}$’ /usr/share/dict/words > words

That plucks out all the five-letter words and stores them in a local file called words. The original dictionary had about 100,000 “words.” There are about 4000 five-letter words left.

I called the python program Here it is


import sys,os,re
input = sys.argv[1]
output = []
for character in input:
    number = ord(character) - 96
for character in input:
    number = ord(character) - 96
    sum += number
newsum = 0
ends = ''
if sum == 51:
    for i in input[3:]:
        number = ord(i) - 96
        newsum += number
        ends = ends + i
    if newsum < 27:
        newl = chr(newsum+96)
        newword = re.sub(ends,newl,input)

I ran it like this:

$ cat words|while read line; do python3 $line >> all-possibilities; done

This plucks out all the five-letter words whose characters add up to 51, and adds the value of the last two letters and creates a new word from them. replacing the last two letters with the new letter.


The results are in.

$ cat all-possibilities

allay allz
avoid avom
bergs berz
beset besy
blocs blov
bombs bomu
broke brop
bused busi
comas comt
condo cons
cribs criu
crude crui
cured curi
dines dinx
elite eliy
erect erew
fates fatx
files filx
flies flix
fluff flul
thick thin

Now, go write your own program. I will share the answer when it's too late to submit - it comes towards the end of the list. It sticks out like a sore thumb - nothing else comes close. So if you just persist you'll see it.


I learned a teensy bit of python, my motivation being to solve the current npr puzzle. And it worked! But my program was surprisingly slow. I guess I wrote it in an inefficient manner.
