Lambdas are quite nice - they let you create a single, one line function
with minimal effort.

def add(x, y):
    return x + y

add2 = lambda x, y: x + y

add(2, 3)    # Returns 5
add2(2, 3)  # Also returns 5

I highly recommend firing up your interpreter and playing around with lambda
functions. There are only a few places that they're appropriate, but they
make those few things a _lot_ easier.

HTH,
Wayne
