使用python将单词“I'm”转换为“I am”[关闭]

Question

使用 python 将单词" I'm" 转换为"I am" 并类似地将"How're" 转换为"How are"。我为此使用了词形还原，但没有得到足够的结果。我使用了以下代码：

sen="You are great, My Lord. I'm studying with co-workers. How're you?" 
all_words=regexp_tokenize(sen, "[\w']+")
lemmatiser = WordNetLemmatizer()
all_words_lem=[]
for i in all_words:
x=lemmatiser.lemmatize(i, pos="v")
all_words_lem.append(x)

我会使用更易读、更容易维护的东西：

import re

def decontracted(phrase):
    # specific
    phrase = re.sub(r"won't", "will not", phrase)
    phrase = re.sub(r"can\'t", "can not", phrase)

    # general
    phrase = re.sub(r"n\'t", " not", phrase)
    phrase = re.sub(r"\'re", " are", phrase)
    phrase = re.sub(r"\'s", " is", phrase)
    phrase = re.sub(r"\'d", " would", phrase)
    phrase = re.sub(r"\'ll", " will", phrase)
    phrase = re.sub(r"\'t", " not", phrase)
    phrase = re.sub(r"\'ve", " have", phrase)
    phrase = re.sub(r"\'m", " am", phrase)
    return phrase


test = "Hey I'm Yann, how're you and how's it going ? That's 
interesting: I'd love to hear more about it."
print(decontracted(test))
# Hey I am Yann, how are you and how is it going ? That is interesting: I would love to hear more about it.
