and conclude that the last one is clearly the best. It turns out that “Yankees” and “New York Yankees” are a perfect partial match…the shorter string is a substring of the longer. We have a helper function for this too (and it’s far more efficient than the simplified algorithm I...
) else: print("The strings are not a fuzzy match.") 在这个示例中,string1和string2的相似度得分为90,超过了设定的阈值80,因此判断它们为模糊匹配。 通过上述步骤,你可以轻松地在Python中实现两个字符串的模糊匹配。如果你有更复杂的需求,例如从列表中查找与目标字符串最相似的项,可以进一步探索fuzzywuzzy库...
上面代码涉及了一个导入问题,即先从当前文件StringMatcher中导入StringMatcher,如果导入出现异常,就去difflib中导入SequenceMatcher。 正如上面第一张图中看到的,当然文件夹下面确实有一个叫StringMatcher.py的文件,也看看它前面的代码: from Levenshtein import * from warnings import warn class StringMatcher: ... .....
print(best_match) # 输出:('fuzzy matching in Python', 100) 二、使用正则表达式进行模糊检索 正则表达式是一种强大的字符串处理工具,也可以用于实现简单的模糊检索,特别是在需要根据特定模式匹配时。 1、基本用法 Python的re模块提供了丰富的正则表达式功能。
我们还可以使用"socer_cutoff"参数来设置最佳匹配分数的阈值。如果最佳匹配分数低于阈值,则会返回None,如下面的代码片段所示: 将FuzzyMatch应用于整个数据集 下面的代码片段淹死了如何将模糊屁哦EI应用与整个dataset_1列中,以针对dataset_2的列返回最佳分数,其中计分器为"token_set_ratio",score_cutoff为90...

Fuzzy string matching like a boss. It uses Levenshtein Distance to calculate the differences between sequences in a simple-to-use package.
