Question

我最近开始学习python，并且尝试将单词列表分类为：正数“ pos”和负数“ neg”

我正在寻找的结果是：

('joli': 'pos', 'bravo': 'pos', 'magnifique': 'pos')
('arnaque': 'neg', 'désagréable': 'neg', 'mauvais': 'neg')

我有以下代码：

def word_feats(words):
    return dict([(word, True) for word in words])


vocab_positif = [ 'joli', 'bravo', 'magnifique']
vocab_negatif = [ 'arnaque', 'désagréable','mauvais']


positive_features = [(word_feats(vocab_positif), 'pos')]
negative_features = [(word_feats(vocab_negatif), 'neg')]

输出：

({'joli': True, 'bravo': True, 'magnifique': True}, 'pos')
({'arnaque': True, 'désagréable': True, 'mauvais': True}, 'neg')

Answer 1

如果给出更多上下文，则可以用更好的方式编写，但我认为此解决方案与您期望的输出匹配。

def word_feats(words, val):
    return {word: val for word in words}


vocab_positif = [ 'joli', 'bravo', 'magnifique']
vocab_negatif = [ 'arnaque', 'désagréable','mauvais']

features = {}
positive_features = word_feats(vocab_positif, 'pos')
negative_features = word_feats(vocab_negatif, 'neg')

print(positive_features)
print(negative_features))

输出：

{'joli': 'pos', 'bravo': 'pos', 'magnifique': 'pos'}
{'arnaque': 'neg', 'désagréable': 'neg', 'mauvais': 'neg'}

如果需要，可以合并dict，例如：

combined = {**positive_features, **negative_features}

或类似的东西

features = {}
features.update(word_feats(vocab_positif, 'pos'))
features.update(word_feats(vocab_negatif, 'neg'))
print(features)

Answer 2

这应该为您提供所需的输出：

def word_feats(words, desc):
    return dict([(word, desc) for word in words])

vocab_positif = [ 'joli', 'bravo', 'magnifique']
vocab_negatif = [ 'arnaque', 'désagréable','mauvais']

positive_features = word_feats(vocab_positif, 'pos')
negative_features = word_feats(vocab_negatif, 'neg')
