The Lambda Function

The lambda function is a dynamic way of compacting functions inside the code.
For example, the function:
>>> def area(b, h):
...          return 0.5*b*h
...
>>> area(5, 4)
10.0

this function can be compacted by using lambda function, like this:
>>> area = lambda b, h: 0.5*b*h
>>> area(5, 4)
10.0
