The lambda form:
Using lambda keyword tiny anonymous functions can be created.
It is a very powerful feature of Python which declares a one-line unknown small function on the fly. The lambda is used to create new function objects and then return them at runtime.
The general format for lambda form is:
lambda parameter(s): expression using the parameter(s)
For instance k is lambda function-
>>> k= lambda y: y + y
>>> k(30)
60
>>> k(40)
80
The assert statement:
The build-in assert statement of python introduced in version 1.5 is used to assert that something is true.
Programmers often place assertions at the beginning of a function to check for valid input, and after function call to check for valid output. Assert statement can be removed after testing of program is over.
If assert evaluates to be false, an AssertionError exception is raised. AssertionError exceptions can be handled with the try-except statement.
The general syntax for assert statement is:
assert Expression[, Arguments]
