Python 3.x python中单词的动名词形式

我想知道字符串的动名词形式。我还没有找到一种直接的方法来调用库来获取动名词

我对以“ing”结尾的单词应用了这些规则，但由于异常，我遇到了一些错误。然后，我将对照cmu单词进行检查，以确保生成的动名词词是正确的。代码如下所示：

import cmudict
import re

ing= 'ing'
vowels = "aeiou"
consonants = "bcdfghjklmnpqrstvwxyz"
words=['lead','take','hit','begin','stop','refer','visit']
cmu_words= cmudict.words()
g_w = []

for word in words:
    if word[-1] == 'e':
        if word[:-1] + ing in cmu_words:
            g_w.append(word[:-1] + ing)             
    elif count_syllables(word) == 1 and word[-2] in vowels and word[-1] in consonants:
        if word.__len__()>2 and word[-3] in vowels:
            if word + ing in cmu_words:
                g_w.append(word + ing)                 
        else:
            if word + word[-1] + ing in cmu_words:
                g_w.append(word + word[-1] + ing)
    elif count_syllables(word)>1 and word[-2] in vowels and word[-1] in consonants:
        if word + word[-1]+ ing in cmu_words:
            g_w.append(word + word[-1]+ ing)            
        else:
            if word + ing in cmu_words:
                g_w.append(word + ing) 
    
print(g_w)

规则如下：

when a verb ends in "e", drop the "e" and add "-ing". For example: "take + ing = taking".
when a one-syllable verb ends in vowel + consonant, double the final consonant and add "-ing". For example: "hit + ing = hitting".
When a verb ends in vowel + consonant with stress on the final syllable, double the consonant and add "-ing". For example: "begin + ing = beginning".
Do not double the consonant of words with more than one syllable if the stress is not on the final

如果存在字符串，是否有更有效的方法获取其动名词

也许这就是你要找的。称为Pyinfoct

用于单词屈折变化的python模块，用作空间扩展。要使用standalone，请导入方法getAllInflections和/或getInflection并直接调用它们。getInflection方法接受一个引理和一个Penn Treebank标记，并返回与之相关联的特定屈折变化的元组

有各种各样的标记可用于获取屈折变化，包括“VBG”标记动词，您正在寻找的动名词

pos_type = 'A'
* JJ      Adjective
* JJR     Adjective, comparative
* JJS     Adjective, superlative
* RB      Adverb
* RBR     Adverb, comparative
* RBS     Adverb, superlative

pos_type = 'N'
* NN      Noun, singular or mass
* NNS     Noun, plural

pos_type = 'V'
* VB      Verb, base form
* VBD     Verb, past tense
* VBG     Verb, gerund or present participle
* VBN     Verb, past participle
* VBP     Verb, non-3rd person singular present
* VBZ     Verb, 3rd person singular present
* MD      Modal

下面是一个示例实现

#!pip install pyinflect
from pyinflect import getInflection

words = ['lead','take','hit','begin','stop','refer','visit']
[getInflection(i, 'VBG') for i in words]

注：作者已经建立了一个更复杂和基准化的库，该库同时进行lemmatization和屈折，称为LemmInflect。如果您想要比上述库更可靠的内容，请务必查看。语法与上面的基本相同。
