Types of function

Types of function:

Functions can be classified into two categories:

i)               user defined function

ii)             Built in function

i) Built in functions

v   Built in functions are the functions that are already created and stored in python.

These built in functions are always available for usage and accessed by a programmer. It cannot be modified.

ii)User Defined Functions:

v   User defined functions are the functions that programmers create for their requirement and use.

v   These functions can then be combined to form module which can be used in other programs by importing them.

v   Advantages of user defined functions:

·                 Programmers working on large project can divide the workload by making different functions.

·                 If repeated code occurs in a program, function can be used to include those codes and execute when needed by calling that function.
