Python匹配相似的字符串，并从两个列表中将它们分组在一起

import Levenshtein

def group_similar_strings(list1, list2, threshold):
    groups = []
    for str1 in list1:
        group = [str1]
        for str2 in list2:
            distance = Levenshtein.distance(str1, str2)
            similarity = 1 - (distance / max(len(str1), len(str2)))
            if similarity >= threshold:
                group.append(str2)
        groups.append(group)
    return groups

list1 = ["apple", "banana", "orange"]
list2 = ["aple", "bananna", "orng"]
threshold = 0.8

result = group_similar_strings(list1, list2, threshold)
print(result)

[['apple', 'aple'], ['banana', 'bananna'], ['orange', 'orng']]
