my code is:

import re  import json    pattern_split = re.compile(r"\w+")   def sentment_tbl(sent_file):     # read in afinn-111.txt     tbl = dict(map(lambda (w, s): (w, int(s)), [     ws.strip().split('\t') ws in open(sent_file)]))     return tbl  def sentiment(text,afinn):     # word splitter pattern      words = pattern_split.split(text.lower())     sentiments = map(lambda word: afinn.get(word, 0), words)     if sentiments:         sentiment = float(sum(sentiments))     else:         sentiment = 0     return sentiment  def main():      sent_file = sys.argv[1]     afinn = sentment_tbl(sent_file)      tweet_file = (sys.argv[2])     open(tweet_file) f:        line_str in f:         print type(line_str)         print line_str         tweet = json.loads(line_str.read())         print("%6.2f %s" % (sentiment(line_str,afinn)))       #test: text = "finn stupid , idiotic"     #print("%6.2f %s" % (sentiment(text,afinn), text))   if __name__ == '__main__':     main()

thanks, chris

if you've written multiple tweets file. eg:

 o.write(tweet1)  o.write(tweet2) 

you have read them in line line well, because json can't decode file of multiple objects written line line.

tweets = [] line in open('test.txt', 'r'):     tweets.append(json.loads(line))
