"sqlite3.operationalerror unrecognized token" error

Question

I have a project in which I have implement a Search Engine. Our guide suggested us to implement the code given in O' Reilly's Collective Intelligence 2007 book. This is a part of the code where a webpage is indexed. We are making use of Sqlite3 database. I get error in the last part of the code and even after researching a lot, I have had no success.

    def addtoindex(self,url,soup):
     if self.isindexed(url): return
     print 'Indexing '+url
     # Get the individual words
     text=self.gettextonly(soup)
     words=self.separatewords(text)
     # Get the URL id
     urlid=self.getentryid('urllist','url',url)
     # Link each word to this url
     for i in range(len(words)):
      word=words[i]
      if word in ignorewords: continue
      wordid=self.getentryid('wordlist','word',word)
      self.con.execute("insert into wordlocation(urlid,wordid,location)\values (%d,%d,%d)" % (urlid,wordid,i))

I am getting the following error in the last line:

sqlite3.OperationalError: unrecognized token: "[some symbol i don't know]"

Answer 1

Remove the backslash from the SQL command.

In Python, \v specifies a control character (a vertical tab).
