I am trying to get the tweets of a list of users into an object in Python using Tweepy, with the intention of iterating through every tweet and passing it into a text classification algorithm.

The array where the tweets are saved in, is of the form:

tweets = [[tweet.id_str+screen_name, 0, tweet.text.encode("utf-8")] for tweet in alltweets]

So what I need is to iterate through every row of the array and get the string (the tweet text) of the third column.

What is the proper syntax for doing it?

    This is an array of arrays, not of tuples. It doesn't matter for @BardiHarborow's answer, but perhaps worth pointing out. – unwind Jun 01 '16 at 13:48

    In fact it's a list of lists. An [`array`](https://docs.python.org/3/library/array.html) is something different in Python. – Matthias Jun 01 '16 at 14:18

Based on what you provided:

tweet_texts = [tweet[2].decode("utf-8") for tweet in tweets]

  • Why this does not work? csvtweets = [[tweet.id_str+screen_name, 0, tweet.text.encode("utf-8")] for tweet in alltweets] tweet_texts = [csvtweets[3] for row in csvtweets] print tweet_texts Instead, the output is all the 3 objects that every row/array (as @unwind said) has. Shouldn't the 3 in the brackets identify the column i want to get from every row? – Yanis Kartalis Jun 01 '16 at 14:02
  • @YanisKartalis, Python uses [0-based indexing](http://python-history.blogspot.com.au/2013/10/why-python-uses-0-based-indexing.html), i.e. the first element is actually referred to as the 0th element. – Bardi Harborow Jun 01 '16 at 14:05
  • Thank you @Bardi Harborow ! this solved my issue :) – Yanis Kartalis Jun 01 '16 at 14:08
