Percentage of how similar strings are in Python? [closed]
2024/10/6 0:35:59
I don't know how to do a program that gives a percentage of how similar two strings of the same length are.
For example, for abcd and abce it should give 75%.
The order matters, I don't want that it gives me that abcd and dcab have a 100%.
I know that Levenshtein module does that, but I want a program that does it.
Answer
>>> from difflib import SequenceMatcher
>>> SequenceMatcher(None, 'abcd', 'abce').ratio()
0.75
Read the docs for more. You can read the description in the docs to figure out how to do it yourself, but you're going to end up coding some kind of alignment algorithm from scratch.
