Find words which contains all the vowels

Find words which contains all the vowels is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Task

Use the dictionary  unixdict.txt

Find the words which contains all the vowels,   but each vowel should appear only once in a word.

The length of any word shown should have a length   >  10.

Python

Tested on Python 3+, the file download will work only if the link is still active. It is possible that you may be able to fetch the file in your browser but download via code may still fail. Check whether you are connected to a VPN, it works on open networks. <lang Python> import urllib.request from collections import Counter

urllib.request.urlretrieve("http://wiki.puzzlers.org/pub/wordlists/unixdict.txt", "unixdict.txt")

dictionary = open("unixdict.txt","r")

wordList = dictionary.read().split('\n')

dictionary.close()

for word in wordList:

   if len(word)>10:
       frequency = Counter(word.lower())
       if frequency['a']==frequency['e']==frequency['i']==frequency['o']==frequency['u']==1:

R

Adapting this from https://rosettacode.org/wiki/Find_words_which_contain_the_most_consonants#R is trivial. <lang R>dict <- scan("https://web.archive.org/web/20180611003215/http://www.puzzlers.org/pub/wordlists/unixdict.txt", what = character()) dictBig <- dict[nchar(dict) > 10]

1. The following line is equivalent to sapply(c("a", "e", "i", "o", "u"), function(x) stringr::str_count(dictBig, x))
2. As with all things with strings in R, life is easier with stringr or stringi.

vowelCount <- sapply(c("a", "e", "i", "o", "u"), function(x) lengths(regmatches(dictBig, gregexec(x, dictBig)))) dictBig[apply(vowelCount, MARGIN = 1, function(x) all(x == 1))]</lang>

REXX

These REXX versions don't care what order the words in the dictionary are in,   nor does it care what
case  (lower/upper/mixed)  the words are in,   the search for the words is   caseless.

They also allows the minimum length to be specified on the command line (CL) as well as the dictionary file identifier.
