Python get instance from list based on instance variable

Given a list of instances, say clients I'm trying to pluck an item from the list based on the value of a single instance variable screenName. I know I can do this:

for client in clients:
  if client.screenName = search:
    return client

But is there a nicer way of doing this without the loop?

Thanks for your help :)

Solution

  • You can use filter 

    try:
    filter(lambda client: client.screenName == search, clients)[0]
except IndexError:
    # handle error. May be use a default value
