I have a report that i am creating and distributing using the system.report.executeAndDistribute function on a button press, but with our ever changing group of workers I am constantly updating the e-mail addresses. Is there a function to use an on-call roster since that can be changed with a few clicks?

From the [manual](https://docs.inductiveautomation.com/display/DOC79/system.alarm.getRosters)

```auto
rosters = system.alarm.getRosters()

for key, values in rosters.iteritems():

    # key is the roster name, values is a dict of usernames

    print 'Roster', key, 'contains these users:'

    for value in values:

        print ' ', value

```

So that gets me all of the rosters and the names of the people in them. But how can I use that to create an e-mail list from a individual roster to use system.report.executeanddistribute?

No user source tpye was specified, but this assumes the users are in an internal user source.

```python
rosterUsers = rosters['rosterName']

userInfo = system.user.getUsers('default')

contacts = [user.contactInfo for user in userInfo if user.get('username') in rosterUsers]

print contacts

```
