Levenshtein module in python doesn't work

Question

I installed the module python-Levenshtein-0.11.2. I think the setup succeeded (when I type help('modules'), I see "Levenshtein" module in the list).

But when I tried the "distance" function, I got this error: "NameError: name 'distance' is not defined".

I can't understand why the distance function doesn't work.

Answer 1

You're not forgetting to use the module namespace are you?

Calls should look something like this:

import Levenshtein
lev_dist = Levenshtein.distance(args)

Alternatively, you can make distance() accessible without the module. bit by doing:

from Levenshtein import distance
lev_dist = distance(args)
