python - not being able to write the last row into csv -


my parent dataset contains 1 tweet in each row. cleaning tweets , extracting feature words tweets , exporting csv. being able export 1 last row. using follwoing piece of code:

#read tweets 1 one , process fp = open('c:/twitter_crawl/tweetdb4_import.csv', 'r')   st = open('c:/twitter_crawl/stopwords.txt', 'r') stopwords = getstopwordlist('c:/twitter_crawl/stopwords.txt')  line in fp.readlines():     = csv.writer(open('feature_vector.csv', 'a'))     processedtweet = processtweet(line)     featurevector = getfeaturevector(processedtweet)     a.writerow(featurevector)     print (featurevector) #end loop fp.close()

can please me out looping last row gets exported?

thanks in advance!

you need close file feature_vector.csv. opening every time through loop, bad. open once before loop , close once afterward.

also variable st not used.
