+# tweet_scraper
+this project can be used to scrape tweets and append them to previously scraped tweets from the same user.
+I built this so I could accumulate twitter data and train an RNN on it so it can post to twitter itself. 
+
+The RNN I am using is also open source and can be found here https://github.com/jcjohnson/torch-rnn
+
+Usage 
+
+```
+python getTweets.py screen_name amount [filename]
+```
+
+The filename is an optional argument to specify which file you want to write the tweets to
+The filename can be used to append to files
+
+The id of last tweet scraped is kept in a file called lastTweetScraped.txt which will be created if it does not exist in the current directory.
+
+TODO's:
+
+add specifity for arguments
+-f file
+-af append to file
+-stop Scrape only new tweets, ie. all up to last tweet scraped as specified in the lastTweetScraped.txt file
+
+Maybe scrape just a range
+Better File I/O functionality
