How to use string as input for csv reader without storing it to file

Question

I'm trying to loop through rows in a csv file. I get csv file as string from a web location. I know how to create csv.reader using with when data is stored in a file. What I don't know is, how to get rows using csv.reader without storing string to a file. I'm using Python 2.7.12.

I've tried to create StringIO object like this:

from StringIO import StringIO

csv_data = "some_string\nfor_example"
with StringIO(csv_data) as input_file:
    csv_reader = reader(csv_data, delimiter=",", quotechar='"')

However, I'm getting this error:

Traceback (most recent call last):
  File "scraper.py", line 228, in <module>
    with StringIO(csv_data) as input_file:
AttributeError: StringIO instance has no attribute '__exit__'

I understand that StringIO class doesn't have __exit__ method which is called when when finishes doing whatever it does with this object.

My answer is how to do this correctly? I suppose I can alter StringIO class by subclassing it and adding __exit__ method, but I suspect that there is easier solution.

Update:

Also, I've tried different combinations that came to my mind:

with open(StringIO(csv_data)) as input_file:

with csv_data as input_file:

but, of course, none of those worked.

Answer 1

>>> import csv
>>> csv_data = "some,string\nfor,example"
>>> result = csv.reader(csv_data.splitlines())
>>> list(result)
[['some', 'string'], ['for', 'example']]
