QLev 1.9.1

String distance metrics based on Levenshtein and Qwerty Matrix Distance

QLev

Introduction

The QLev package is mainly used for:

• Levenshtein distance
• levenshtein distance normalized
• levenshtein distance considering the keyboard keys range

Requirements

• Python 3 or later

Installation

pip install QLev

Guide

To use simple the levenshtein distance you can:

from QLev import levenshteinDistance

diff = levenshteinDistance('Guacamole','Guecamole')

print(diff)

If you want to use the normalized metric, you can:

from QLev import levN

diff = levN('Guacamole','Guecamole')

print(diff)

If you want to know the euclidian distance between two chars, you can:

from QLev import qwertyDistance

diff = qwertyDistance('g','a')

print(diff)

To have a metric that uses the qwerty matrix between strings, you can:

from QLev import qwertyN

diff = qwertyN('Guacamole','Guecamole')

print(diff)

To have a metric that uses levenshtein distance and the qwerty matrix between strings, you can:

from QLev import QLev

diff = QLev('Guacamole','Guecamole')

print(diff)
