Python: CSV file is still Blank after writing Data

Question

I have a Tuple result from mysql like this :

sqlResult=({'Count': 1L, 'gname': 'Anron may'}, {'Count': 1L, 'gname': 'Anchy de'}, {'Count': 1L, 'gname': 'abby ras'}, {'Count': 2L, 'gname': 'Akki nome'}, {'Count': 41L, 'gname': 'Archenemy'}, {'Count': 1L, 'gname': 'Antony papa'}, {'Count': 1L, 'gname': 'Dead zombie'})

I am trying to save this data to CSV file like this

import time
csvName="Gnames-and-count-"+str(int(time.time()))
csvPath="/home/sean/Desktop/"+str(csvName)+str(".csv")
writer = csv.writer(open(csvPath, 'wt'))
for results in sqlResult:
    writer.writerow([results['gname'],int(results['Count'])])

The file is created at the following path but nothing is there on the file. Is there any obvious thing i am missing? .Please guide me.

Answer 1

You need to close the file. Let with do it for you.

with open(csvPath, 'w') as f:
    writer = csv.writer(f)
    for results in sqlResult:
        writer.writerow([results['gname'],int(results['Count'])])

Answer 2

Instead of directly write into csv file write into standard out put and saves the result in file_name.csv

import csv
import sys
...
...

writer=csv.writer(sys.stdout)

...

then for taking output in csv

you can write command like this :-

$ program_name > my_spreadsheet.csv 

Hope it will help you...
