Hi,
I have a dict named "connections", with items like the following:
In [18]: connections
Out[18]:
{'3424234': {'end_timestamp': datetime.datetime(2015, 3, 25, 5, 31, 30, 406000,
tzinfo=datetime.timezone(datetime.timedelta(-1, 61200))),
'ip_address': '10.168.8.36:52440',
'open_timestamp': datetime.datetime(2015, 3, 25, 5, 31, 0, 383000,
tzinfo=datetime.timezone(datetime.timedelta(-1, 61200))),
'time_open': datetime.timedelta(0, 30, 23000)}}
In this case, the key is a connection id (e.g. "3424234"), and the value is a
another dict, which contains things like 'end_timestamp', 'ip_address" etc.
I'm writing the output of "connections" to a CSV file using DictWriter:
fieldnames = ['connection_id', 'ip_address', 'open_timestamp', 'end_timestamp',
'time_open']
with open('output.csv', 'w') as csvfile:
writer = DictWriter(csvfile, fieldnames)
writer.writeheader()
for connection, values in sorted(connections.items()):
if 'time_open' in values:
writer.writerow(values, {'connection_id': connection})
else:
pass
# DO SOME STUFF
The only problem is, I'd also like output the connection_id field as part of
each CSV record.
However, connection_id in this case is the key for the parent dict.
Is there a clean way to add a extra field to DictWriter writerows, or it is the
contents of the dict and that's it?
Cheers,
Victor
