nope.  lambdas can only contain simple expressions.

also see:

    http://www.python.org/doc/FAQ.html#6.9
    6.9. Why can't lambda forms contain statements?

    "...the only advantage of using a lambda form instead of
    a locally-defined function is that you don't need to invent
    a name for the function..."
