python 中 for 循环的聚合结果

Question

我正在 python 进行情绪分析。清理完要使用的推文后，我一直坚持获取每条推文的最终情绪分数。我正在获取这些值，但无法将每条推文汇总为一个分数。这是代码

scores = {} # initialize an empty dictionary  
for line in sent_file:  
    term, score = line.split("\t") 
    scores[term] = int(score) # Convert the score to an integer.  



for line in tweet_file:  
       #convert the line from file into a json object  
    mystr = json.loads(line) 
    #check the language is english, if "lang" is among the keys  
    if 'lang' in mystr.keys() and mystr["lang"]=='en':  
            #if "text" is not among the keys, there's no tweet to read, skip it  
        if 'text' in mystr.keys(): 
            print mystr['text']
            resscore=[] 
            result = 0
            #split the tweet into a list of words  
            words = mystr["text"].split() 
            #print type(words)
            for word in words:  

                if word in scores:  
                    result = scores[word]
                    resscore.append(result)

                    print str(sum(resscore))


                else:  
                    result+=0

我得到的输出是这样的

If nothing is as you'd imagine it to be then you may as well start imaging some mad stuff like dragons playing chess on a…
 -3
 -1

但我希望将本例中的这些值 -3、-1 聚合起来，得出该推文的最终分数，即 -4。谢谢

累积这些值并在循环结束后打印它们：

# ...

finalScore = 0 # final score
for word in words:

    if word in scores:
        result = scores[word]
        resscore.append(result)

        finalScore += sum(resscore)

print(str(finalScore))

# ...
