Hi Vineeth ,

Lambda's form a very convenient short-cut notation for defining
functions on the fly - especially when you wish to pass them to
functions. For example:

map(lambda x:x*x, [1,2,3])

Is far more convenient than first defining a "sqr" function and then
calling map with sqr as parameter. Also, when you code in a functional
style, you will make very heavy use of "little" functions for the
purpose of passing them onto some other function - it doesn't make
sense to define all these little functions by name ..
