Does python determine if a word is a valid English word? --Three ways

for (much) more power and flexibility, use a dedicated spellchecking the library like PyEnchant . There ' s a tutorial, or could just dive straight in:

>>> ImportEnchant>>>D=Enchant.Dict("en_US")>>>D.Check("Hello")True>>>D.Check("Helo")False>>>D.Suggest("Helo")[ ' He lo ' ,  ' He-lo ' ,  ' Hello ' , ' helot ' ,  ' help ' ,  ' Halo ' ,  ' Hell ' ,  ' Held ' ,  ' Helm ' ,  ' Hero ' ,  "He" ll "]>>>     

PyEnchantComes with a few dictionaries (EN_GB, en_US, De_de, fr_fr), but can and any of the OpenOffice ones if you want more Langua Ges.

Using a set to store the word list because looking them up would be faster:

WithOpen("English_words.txt") AsWord_file:English_words=Set(Word.strip ().  ()  for Word in< Span class= "PLN" > Word_file) def Is_ English_word (word  Word. ()  in english_words print Is_english_word ( "Ham" )  # should is true if you have a good english_words.txt  span>                 

To answer the second part of the question, the plurals would already is in a good word list, and if you wanted to specific Ally exclude those from the list for some reason, you could indeed write a-function to handle it. But 中文版 pluralization rules is tricky enough that I ' d just include the plurals in the word list to begin with.

As to where to find 中文版 word lists, I found several just by googling "中文版 word list". Here's one:http://www.sil.org/linguistics/wordlists/english/wordlist/wordsen.txt you could Google for British or American 中文版 If you want specifically one of the those dialects.

Using NLTK:

from nltk.corpus import wordnetif not wordnet.synsets(word_to_test): #Not an English Wordelse: #English Word

You should refer the article if you had trouble installing wordnet or want to try other approaches.
