Ternary operator alternative in Ptyhon

[kretik]

I'm sure this is a popular one, but after Googling for a while I 
couldn't figure out how to pull this off.

Let's say I have this initializer on a class:

     def __init__(self, **params):

I'd like to short-circuit the assignment of class field values passed in 
this dictionary to something like this:

	self.SomeField = \
     params.has_key("mykey") ? params["mykey"] : None)

Obviously I know this is not actual Python syntax, but what would be the 
equivalent? I'm trying to avoid this, basically:

     if params.has_key("mykey"):
         self.SomeField = params["mykey"]
     else:
         self.SomeField = None

This is not a big deal of course, but I guess my main goal is to try and 
figure out of I'm not missing something more esoteric in the language 
that lets me do this.

Thanks in advance.
