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.
