title: SnowballStemmer for Russian words list
body: <p>I do know how to perform SnowballStemmer on a single word (in my case, on russian one). Doing the next things:</p>
  
  <pre><code>from nltk.stem.snowball import SnowballStemmer 
  
  stemmer = SnowballStemmer("russian") 
  stemmer.stem("Василий")
  'Васил'
  </code></pre>
  
  <p>How can I do the following if I have a list of words like ['Василий', 'Геннадий', 'Виталий']?</p>
  
  <p>My approach using for loop seems to be not working :( </p>
  
  <pre><code>l=[stemmer.stem(word) for word in l]
  </code></pre>
