mongodb - Remove multiple documents from mongo in a single query

Question

I have a list of mongo '_id' which I want to delete. Currently I am doing this

# inactive_users -->  list of inactive users 
for item in inactive_users:
    db.users.remove({'_id' : item})

but my problem is the list is too huge... (it might go 100,000 +). So querying for every item in list will only increase the load on server. Is their a way to pass the entire list in mongo query so that I dont have to fire query again and again.

Thank you
