Python Question

Python write to CSV line by line

I have data which is being accessed via http request and is sent back by the server in a comma separated format, I have the following code :

site= 'www.example.com'
hdr = {'User-Agent': 'Mozilla/5.0'}
req = urllib2.Request(site,headers=hdr)
page = urllib2.urlopen(req)
soup = BeautifulSoup(page)
soup = soup.get_text()
text=str(soup)


The content of text is as follows:

april,2,5,7
may,3,5,8
june,4,7,3
july,5,6,9


How can I save this data into a CSV file.
I know I can do something along the lines of the following to iterate line by line:

import StringIO
s = StringIO.StringIO(text)
for line in s:


But i'm unsure how to now properly write each line to CSV

EDIT---> Thanks for the feedback as suggested the solution was rather simple and can be seen below.

Solution:

import StringIO
s = StringIO.StringIO(text)
with open('fileName.csv', 'w') as f:
for line in s:
f.write(line)

Answer

General way :

##text=List of strings to be written to file
with open('csvfile.csv','wb') as file:
    for line in text:
        file.write(line)
        file.write('\n')

OR

Using CSV writer :

import csv
with open(<path to output_csv>, "wb") as csv_file:
        writer = csv.writer(csv_file, delimiter=',')
        for line in data:
            writer.writerow(line)

OR

Simplest way:

f = open('csvfile.csv','w')
f.write('hi there\n') #Give your csv text here.
## Python will convert \n to os.linesep
f.close()
