Question

我和一个朋友正在使用FuzzyWuzzy进行近似字符串匹配（假设是哈哈），以从JSON（具体来说是Steam API JSON）生成的数组中查找给定的输入。

这是我们用来从JSON生成数组的代码，其中path是保存在磁盘上的JSON的路径，而array_location只是为了提取游戏ID和游戏名称。

def array_from_json_file(path, array_location):
    array = {}
    with open(path, encoding='utf-8') as f:
        array = json.load(f)
    array = enumerate_json(array, array_location)
    return array

这是遍历整个列表以进行模糊匹配的代码，其中query是用户输入，data是我们从JSON生成的数组，而str_location是所以只搜索名称而不是ID

def fuzzy_query(query, data, str_location):
    results = []
    for i in range(0, len(data)):
        target = enumerate_json(data[i], str_location)
        if (len(target) > 1):
            strength = fuzz.partial_ratio(query.lower(), target.lower()) # This is where the issue is
            results.append((strength, data[i]))
    return results

最后，当我运行脚本时得到的回溯

Traceback (most recent call last):
  File "main.py", line 81, in <module>
    main()
  File "main.py", line 73, in main
    query_results = fuzzy_query(query, games, ["name"])
  File "main.py", line 45, in fuzzy_query
    strength = fuzz.partial_ratio(query.lower(), target.lower())

    self._str1, self._str2)
ValueError: apply_edit edit operations are invalid or inapplicable

我的朋友和我在Python版本（v3.6.6）和FuzzyWuzzy版本（v0.17.0）中都具有相同的版本。当我运行Windows 10 LTSB时，他正在使用Ubuntu。他在运行我们的脚本时没有任何问题。据我们所知，没有环境差异会导致此问题。

遍历数组时发生ValueError
