FuzzyWuzzy 错误：StringProcessor.replace_non_letters_non_numbers_with_whitespace(s)

Question

我无法获得以下功能运行:

match, match_score = process.extractOne(score, pct_dict.keys())

我收到一个似乎无法解决的空白错误。知道是什么原因造成的吗？

它应该做什么：如果分数是 15 它应该 return 0.026

错误：

代码：

from __future__ import unicode_literals
from django import template
from fuzzywuzzy import fuzz
from fuzzywuzzy import process


register = template.Library()


@register.simple_tag
def get_perc(score):
    MATCH_THRESHOLD = 80
    pct_dict = {14: 0.016, 14.7: 0.021, 15.3: 0.026, 16: 0.034, 16.7: 0.04, 17.3: 0.05, 18: 0.07, 18.7: 0.09,
                    19.3: 0.11, 20: 0.13, 20.7: 0.17, 21.3: 0.21, 22: 0.26, 22.7: 0.31, 23.3: 0.38, 24: 0.47}
    if not score:
        return '--'
    elif score < 26.7:
        return '<1'

    match, match_score = process.extractOne(score, pct_dict.keys())

    if match_score >= MATCH_THRESHOLD:
        return pct_dict[match]
    else:
        return '--'

Answer 1

根据 fuzzywuzzy 文档，您需要比较两个字符串。这意味着您需要将字符串中的值转换为比较它们。然后你需要这样做：

match, match_score = process.extractOne(str(score), pct_dict.keys())

我不推荐这种方法，因为它不准确。

>>> x = ['1','2','3']
>>> y='2'
>>> process.extractOne(y,x)
('2', 100)
>>> y='2.2'
>>> process.extractOne(y,x)
('2', 90)
>>> y = '2.9'
>>> process.extractOne(y,x)
('2', 90)

在最后 2 个条目中，您将看到 2.2 和 2.9 的得分 90，其中 2.9 更接近 3。

因为你有数字，我建议你像这样简单地比较它们：

value = min(pct_dict, key=lambda x:abs(x - score))
# then some logics to see if value is close to score or put some static threshold value like `abs(value-score) < .3`

很少有 SO answers 可以帮助您解决这个问题。

Answer 2

谢谢，成功了。感谢您对字符串值的澄清。这允许我设置 str(score) 以将分数值转换为字符串。

这是功能代码：

@register.simple_tag
def get_perc(score):
    MATCH_THRESHOLD = 80
    pct_dict = {'14': '0.016', '14.7': '0.021', '15.3': '0.026', '16': '0.034', '16.7': '0.04', '17.3': '0.05', '18': '0.07', '18.7': '0.09', '19.3': '0.11', '20': '0.13', '20.7': '0.17', '21.3': '0.21', '22': '0.26', '22.7': '0.31', '23.3': '0.38', '24': '0.47'}
    if not score:
        return '--'
    elif score < 24:
        return '<1'

    match, match_score = process.extractOne(str(score), pct_dict.keys())

    if match_score >= MATCH_THRESHOLD:
        return pct_dict[match]
    else:
        return '--'
