Thank you Chris,

 I faced a optimization problem as follow,

For fuzzy string comparison initially i used 15 lines of code which compares
a word with 29,000 words in a list .For each set of words compared, the
15-line code produce number of differences characters of the two words.

But when i used python-levenshtein module for same reason it has run faster
than the old method.This invoked me to raise that query.

Now i understood that, it is not an issue of importing the module/writing
the code, but the problem must be with my 15-line code.
