Hello guys

thanks for the feedback. I think its problem with excel itself, showing wrong 
value. Because when I opened the csv file in text editor, I can see correct 
value but opening in excel showing wrong value. What I can do to see correct in 
excel as well.

Regards

You could tell it to quote any value that's not a number:

        w = csv.DictWriter(f, pol_keys, quoting=csv.QUOTE_NONNUMERIC)

It looks like all of the values you have are strings, so they'll all be
quoted.

I would hope that Excel will then treat it as a string; it would be
stupid if it didn't! :-)

Hello Experts

When I am writing list of dictionaries to CSV file, the key 'schedule' has 
value 'Mar 2012' becomes Mar-12. I really do not have clue why thats happening. 
Below is the code.

dic_1 = {'action': 'permit',
 'dst-address': 'maxprddb-scan-167, maxprddb-scan-168, maxprddb-scan-169',
 'from': 'DMZ Web',
 'id': '1000',
 'log': 'Enable, session-init',
 'name': 'Test Rule Temporary ',
 'service': '1521, Oraccle-Maximo-Scan-1550, PING-ALL',
 'src-address': 'sparkeregap1, sparkeregap2',
 'to': 'Trust'}

dic_2 {'action': 'permit',
 'dst-address': 'sparkcas01, sparkcas02, email.ab.spark.net',
 'from': 'DMZ Web',
 'id': '4000',
 'log': 'Enable, session-init',
 'schedule': 'Mar 2012',
 'service': 'SMTP',
 'src-address': 'sparkeregap1, sparkeregap2',
 'to': 'Trust'}

 my_list =
 [{'to': 'Trust', 'service': '1521, Oraccle-Maximo-Scan-1550, PING-ALL', 
'from': 'DMZ Web', 'dst-address': 'maxprddb-scan-167, maxprddb-scan-168, 
maxprddb-scan-169', 'name': 'Test Rule Temporary ', 'action': 'permit', 'id': 
'1000', 'src-address': 'sparkeregap1, sparkeregap2', 'log': 'Enable, 
session-init'}, {'to': 'Trust', 'from': 'DMZ Web', 'dst-address': 'sparkcas01, 
sparkcas02, email.ab.spark.net', 'service': 'SMTP', 'schedule': 'Mar 2012', 
'action': 'permit', 'id': '4000', 'src-address': 'sparkeregap1, sparkeregap2', 
'log': 'Enable, session-init'}]

 pol_keys = ['id', 'name', 'from', 'to', 'src-address', 'dst-address', 
'service', 'action', 'nat_status', 'nat_type', 'nat_src_ip', 'nat_dst_ip', 
'nat_dst_port', 'log', 'schedule']

with open('test.csv', 'wb') as f:
        w = csv.DictWriter(f, pol_keys)
        w.writeheader()
        w.writerows(my_list)
