How to do this in Python...

I'm puzzled by what seems like a missing piece of functionality in Python.
I suspect there is a simple way to do what I want to do and I'm guessing
someone here can point it out to me. Here is the issue:
In C++, I could write a statement like this:
if (match=re.match(pattern, string))
// do something with the match object
But I cannot figure out how to do the equivalent thing in Python. The idea
here is to have an assignment statement within an if statement so that I
don't have to call match twice or obfuscate the code. It seems to me that
my current options are:
match = re.match(pattern, string)
if match:
// do something with match object
-or-
if re.match(pattern, string):
match = re.match(pattern, string)
The first one seems unnecessarily verbose and the second one is inefficient.
Are there any other options?
