计算lis中每个单词的正负字符串数

Question

我是python新手，希望您能帮助我解决这个问题，我使用的是python3.4。在

我有一个单子，上面有正反两个词，还有频率

这是原始列表：

`finalSentiment = [('hijacked', 'negative'), ('hijacked', 'negative'), ('hijacked', 'negative'),  ('hijacked', 'negative'), ('hijacked', 'negative'), ('hijacked', 'negative'), ('hijacked',

我要做的是计算列表中每个单词的正负数。 所以如果负数比较多，这个词就是负数。 然后我可以列出一个新的清单，比如： 例如：newList = [('hijacked','negative'),('left','negative'), . . .]

a）我尝试使用num = Count(finalSentiment).most_common()[:50]函数，得到如下新列表。在

^{pr2}$

我想做的是比较词的频率，不管是正的还是负的，都是比较高的。 所以，如果negative更高，我想创建一个包含单词和negative的新列表。在

例如：[('hijacked','negative'),('left','negative'), . . .]

每个单词在列表中只能有正数或负数。在

我尝试使用for循环访问列表中的每一项。在

for item in num:

        unique_word = item[0]
        temp = unique_word[0]
        temp1 = unique_word[1]
        frequency = item[1]

但是我不知道在我访问数据之后如何操作它。在

b）我使用counter（）函数并得出以下列表：

cnt = Counter()
for word in finalSentiment:
    cnt[word] += 1
print(cnt)

我现在的问题是如何比较，例如“劫持”这个词，负数更高。因此，在新的列表中，“劫持”应该是“否定的”，因此： 例如：newList=[('hijacked','negative'),('left','negative'), . . .]

c）或者我应该自己计算正数和负数，而不是使用most_common()函数或counter()。 我计算正数和负数的问题是因为列表中有多个单词。如果这个词只是被“劫持”了，加上积极的和消极的，我想我可以解决这个问题。在

任何帮助都将不胜感激。在

Answer 1

from collections import Counter

counts = Counter(finalSentiment)

output = [] 
for word in set(w for w, s in finalSentiment):
    if counts.get((word, 'positive'), 0) > counts.get((word, 'negative'), 0):
        output.append((word, 'positive'))
    else:
        output.append((word, 'negative'))

Answer 2

from collections import Counter
finalSentiment = [('a','negative'),('a','negative'),('a','positive'),('b','positive')]
cnt = Counter(finalSentiment)
noDups = list(set([x[0] for x in set(finalSentiment)]))
newList =[]
for each in noDups:
    if cnt[(each,'positive')] > cnt[(each,'negative')]:
        newList.append((each,'positive'))
    else:
        newList.append((each,'negative'))

newList：
