如何迭代字符串中的某些字符，而其他字符在python中保持相同的位置

Question

我有一段文字，比如说

t = "The climate is super awesome"

通过这样做

from nltk.tokenize import word_tokenize words = word_tokenize(t)

我得到的

>>>words = ["The","climate","is","super","awesome"]

我在字典里有多个单子，每个单子上都有同义词的单子。 例如

dict = {'climate' : [weather,region,zone], 'super' : [excellent, superior, outstanding], 'awesome' : [amazing,great,stunning]}

如何编写代码来获得句子中同义词的排列组合。 假设我们每个词至少或正好有3个同义词。 那么在选定的第一行“t”中总共有3个单词。 因此3到3句话的幂=27句话是可能产生的。你知道吗

Answer 1

我试过这个，似乎奏效了：

import re
words = ["The","climate","is","super","awesome"]
synons = {'climate' : ['weather','region','zone'], 'super' : ['excellent', 'superior', 'outstanding'], 'awesome' : ['amazing','great','stunning']}

phrases = {' '.join(words)}
for word, synonyms in synons.items():
    for syn in synonyms:
        for p in list(phrases):
            phrases.add(re.sub(r"\b%s\b" % word, syn, p))

print('\n'.join(sorted(phrases)))

输出：
