What is a function in programming?
Functions are “self contained” modules of code that accomplish a specific task. Functions usually “take in” data, process it, and “return” a result. Once a function is written, it can be used over and over and over again. Functions can be “called” from the inside of other functions.
What is defined in function?
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. We can write the statement that f is a function from X to Y using the function notation f:X→Y.
What is a function definition in Python?
Defining Functions in Python In computer programming, a function is a named section of a code that performs a specific task. This typically involves taking some input, manipulating the input and returning an output.
WHAT IS function and its uses?

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y.
How function is defined and called in Python?
Function in Python is defined by the “def ” statement followed by the function name and parentheses ( () ) Example: Let us define a function by using the command ” def func1():” and call the function. The output of the function will be “I am learning Python function”.
What is the use of function?
Functions are used for performing the repetitive task or we can say the functions are those which provides us the better efficiency of a program it provides us the facility to make a functions which contains a set of instructions of the repetitive types or we need them in a program at various places Thus a functions …
