title: pyshortener error indecipherable ,
body: <p>I 'm making that mistake here ? For me it is really hidden and do not understand</p>
  
  <p>My code:</p>
  
  <pre><code>import tweepy
  import random
  import time
  from random import shuffle
  from pyshorteners.shorteners import Shortener
  from bs4 import BeautifulSoup as bs4
  import requests
  
  
  def shortenerUrl(url):
  myUrl = url
  shortUrlSystem = Shortener('Osdb')
  urlReturned = format(shortener.short(myUrl))
  return urlReturned
  
  
  i = random.randint(1, 144)
  articleExtractor(i)
  for i in listaCompleta:
      api.update_status(status=i)
      time.sleep(random.randint(247, 383))
  </code></pre>
  
  <p>My error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "mTArt.py", line 73, in &lt;module&gt;
  articleExtractor(i)
  File "mTArt.py", line 67, in articleExtractor
  urlCorta = shortenerUrl(job_url)
  File "mTArt.py", line 37, in shortenerUrl
  urlReturned = format(shortener.short(myUrl))
  NameError: name 'shortener' is not defined
  </code></pre>
  
  <p>then what is the ruling?</p>
