Checking fuzzy/approximate substring existing in a longer string, in Python?

The new regex library that’s soon supposed to replace re includes fuzzy matching.

The fuzzy matching syntax looks fairly expressive, but this would give you a match with one or fewer insertions/additions/deletions.

import regex
regex.match('(amazing){e<=1}', 'amaging')
