Answer 1

尝试difflib.SequenceMatcher：

from difflib import SequenceMatcher
l = ['The One and Only Ivan (Korean Edition)', 'The One and Only Ivan CD', 'The One and Only Ivan', 'The One And Only Ivan (Turtleback School & Library Binding Edition)', 'The One and Only Ivan', 'The One and Only Ivan: A Harper Classic', "The One and Only Ivan Full-Color Collector's Edition", 'The One And Only Ivan', 'The One and Only Ivan', 'One and Only Ivan', 'Paris Match (A Stone Barrington Novel)', 'The One and Only Ivan']
print([i for i in l if all(SequenceMatcher(None, i, x).ratio() < 0.2 for x in l)])

输出：

['Paris Match (A Stone Barrington Novel)']
