To pull a report of metrics while applying segment on just one and not all the metrics

[srivga]

Hi
I am very new to python and I am trying to pull the report through Adobe API.
I have created the following code
analytics = omniture.authenticate('user','sharedsecret')
suite = analytics.suites['reportsuiteid']
report = suite.report.element('XXX',top=5000)
.metrics('visits','pageviews','videostart','entries','bounces')
.range('2015-03-01','2015-03-15',granularity='day')
.filter(segment='Exclude company')
.run()
and this helps me in pulling the data for all the metrics applying the filter but how can I pull the report for all the metrics and apply filter on just two of them.

Any insight in solving the issue would be very helpful.

Thanks in advance..
