In this Python Tutorial for Beginners video I am going to show How to use Functions in Python. So what is a Function ? Function is a group of statements within a program that perform as particular task. ✔ Contents ✔
? – Python Functions
? – Default Arguments, *args and **kwargs (Variable-length Arguments)
? – Lambda, filter, reduce and map A Function Usually one task of a large program.
Functions can be executed in order to perform overall program task.There are two kinds of functions in Python, First are Built-in functions that are provided as part of Python – print(), type(), float(), max() etc. Second type are Functions that we define ourselves and then use (user defined functions). Functions Make you code Simpler, reusable i.e. write the code once and call it multiple times, easy to test and debug and results in faster development time.
So first we will discuss How to declare a function in python and then I will demonstrate a Python function example.
A void function:
Simply executes the statements it contains and then terminates.
A value-returning function:
Executes the statements it contains, and then it returns a value back to the statement that called it.Some functions give back a value; others do not. If a function gives back a value, this is referred to as “returning” the value. #PythonTutorialforBeginners #ProgrammingKnowledge #LearnPython #PythonCourse #FunctionsInPython
