How do I improve the below code, which takes input from a file and does some word analysis? I find a lot of redundancy in it. I want to know a better way of implementing it.

analysis = {}
wordanalysis = {}
found = True 

for line in sys.stdin:
   (n1,n2,n3,n4,n5,n6) = re.split("\t+",line.strip())
   tweet = re.split("\s+", n6.strip().lower())
   #adding tweet id to a dictionary

   for i in range(0, len(tweet)):
     print "{", n1, wordanalysis,"}"
     wordanalysis["word"] = tweet[i]
     wordanalysis["charcount"]= len(tweet[i])

     if len(tweet[i]) > 7:
        wordanalysis["longword"] = found
     else:
        wordanalysis["longword"] = not(found)
     #if 1st char is UpperCase
     if tweet[i].istitle():
        wordanalysis["title"] = found
     else:
        wordanalysis["title"] = not(found)

     if tweet[i].isupper():
        wordanalysis["uppercase"] = found
     else:
        wordanalysis["uppercase"] = not(found)
