我正在尝试实现一个 python 函数,该函数通过使用此 wiki 中的此公式返回文本的 Flesch-Kincaid 可读性测试:Flesch reading-ease test
我还遇到了一个与我回答的目标相同的问题:Converting Readability formula into python function
因此,通过使用它作为一种指南,我在我的实现中采用了类似的方法,并以此作为我的代码结束:
import nltk
import collections
nltk.download('punkt')
nltk.download('gutenberg')
nltk.download('brown')
# DO NOT MODIFY THE CODE BELOW #
import re
VC = re.compile('[aeiou]+[^aeiou]+', re.I)
def count_syllables(word):
return len(VC.findall(word))
def compute_fres(text):
"""Return the FRES of a text.
>>> emma = nltk.corpus.gutenberg.raw('austen-emma.txt')
>>> compute_fres(emma) # doctest: +ELLIPSIS
99.40...
"""
tToken = nltk.word_tokenize(text)
for f in nltk.corpus.gutenberg.fileids():
nsents = len(nltk.corpus.gutenberg.sents(f))
nwords = len(nltk.corpus.gutenberg.words(f))
nsyllables = sum(count_syllables(w) for w in words)
fres = 206.835 - 1.015 * (nwords / nsents) - 84.6 * (nsyllables / nwords)
return len(fres.findall(tToken))
然后我运行我的代码并收到此错误消息:
Error

像其他用户的帖子一样,我的目标是通过实现正确的功能来通过 doctest。我也可以假设他/她和我在同一个编程课上。
我对python有点陌生,所以我不确定我做错了什么。
