使用 fuzzywuzzy ，然后改变 threshold 要满足您的要求：

from fuzzywuzzy import process

threshold = 40

matchlist = [x for x in """
Clarksburg
Fremont
San Leandro
Albuquerque
Columbus
San Jose
Martinez
New York
Alhambra
Unknown
Las Vegas
Dublin
Niagara Falls
""".splitlines() if x]

checklist = [x for x in """
Clarksburg
Closed 10/97
Fre,Nont
Fremong
San L:Eandro
Albuquerue
Clmbs
Sanjse
Martinz
New Yrk
Alambra
00011
L Vegas
Vegas
Ssan jose
Nw Yrk
Colmbus
Klarkburg
Alburque
Dublin
Niegara F
""".splitlines() if x]

for check in checklist:
    match = process.extractOne(check, matchlist)
    print(f"{check} - {match[0] if match[1] > threshold else 'Unknown'}")

这给了我：
