如何在python中匹配两组相似但不精确的坐标

import difflib

coordinates1 = [(1.234, 5.678), (2.345, 6.789), (3.456, 7.890)]
coordinates2 = [(1.235, 5.679), (2.346, 6.788), (3.457, 7.891)]

def fuzzy_match(coordinates1, coordinates2):
    matches = []
    for coord1 in coordinates1:
        best_match = difflib.get_close_matches(coord1, coordinates2, n=1, cutoff=0.8)
        if best_match:
            matches.append((coord1, best_match[0]))
    return matches

matches = fuzzy_match(coordinates1, coordinates2)
for match in matches:
    print("坐标1: {}, 坐标2: {}".format(match[0], match[1]))
