convert an sframe column to a list

Question

I need to convert an SFrame column to a list.

input :

 `+---------+
  |   word  |
  +---------+
  |   love  |
  |  loves  |
  |   easy  |
  | perfect |
  |  great  |
  +---------+`

output:

['love', 'loves', 'easy', 'perfect', 'great']

I tried to use list() function and got error ,searched the docs what I found is to_dict() which can convert sframe to a dictionary. — Mohamed Abdallah, Mar 28 '16 at 00:35
Why would you want to convert a "huge" SArray/SFrame column into a list? — absolutelyNoWarranty, Apr 08 '16 at 02:48

I'm surprised the list function gave you an error. This works for me:

import graphlab as gl
sf = gl.SFrame({'fruit': ['apple', 'banana', 'pear']})
list(sf['fruit'])

Returns:

['apple', 'banana', 'pear']

Oh, I did something stupid. I used ` print_rows(num_rows=5)` to get first 5 rows then i tried to convert it ,but I modified it .Thanks alot – Mohamed Abdallah Mar 28 '16 at 14:31
@MohamedAbdallah You can call .head(5) to get the first 5 rows and not just print them. – Evan Samanas Mar 28 '16 at 17:37
@EvanSamans yeah,but as I am intersted in a sorted column, I used `.topk('column_name', k=5)` – Mohamed Abdallah Mar 28 '16 at 18:50

HINT: you can convert it to an array using:

arr = sf.to_numpy()

Yeah,I know that . I had an idea to convert sframe to an array then from array to list using tolist(),but I need to convert it directly to list when using huge data set ! – Mohamed Abdallah Mar 28 '16 at 00:40
