Recursion and lambda function in python

Recursion and lambda function in python

Hello Friends, I am Nirav. And in this tutorial I going to show you Recursion and lambda function in Python..
So, Let's get Started


Recursive

          We know that a function can call other functions. it is even possible for the function to call it self. These type of construct are termed as recursive function.

EX:- Example for Factorial value using recursive


Advantage of recursive

          1.)It's make code clean and elegant
          2.)Sequence generation is easier


Disadvantage of recursive

          1.)logic behind recursion is hard to follow
          2.)It's hard to debug

Lambda

          Lambda is a function which define without name
          In python normal functions are define using def keyword but lambda function are define using lambda keyword.

Syntax:-  lambda argument = expression

Ex:- Example of lambda function for double value


Use of lambda function

          we use it when we required a nameless function for a short period of time.

Filter in lambda

          Simply filter meaning to filter something...
Ex:- Hear the example for filter even numbers from list


Map in lambda

Ex:- Hear the example of map in lambda

Loop Control Statement

Loop Control Statement Hello Friends, I am Nirav. And in this tutorial I going to show you Loop Control Statement  in Python.. So, Let's get Started What is Loop ?           Loop is a sequence of instruction that is continually repeated until a certain condition is reached.           Ex:- For example one teacher punish boy that  write something until she don't tell him to stop.  That is one loop that boy can't stop until teacher can't tell him to stop Why we use loop statement ?           To execute one think many times. Ex:- if you want to print "hello" ten times than you have to use loop Types of loop  There are mainly 2 types of loop           1.) Entry Control            2.) Exit Control 1.) Entry Control            An entry control loop check the condition first and then after enter the loop body.           Ex:-  For Loop , While Loop 2.) Exit Control            An Exit Control loop execute body first

Boolean Expression and If..else Condition

Boolean Expression and If..else Condition Hello Friends, I am Nirav. And in this tutorial I going to show you Boolean Expression and If..else Condition in Python.. So, Let's get Started What is Boolean Expression ?          it's a expression that result in a Boolean value that is, in a value of wither true or false. If Condition Decision making is required when we want to execute a code only if a certain condition is satisfied. The if..elif..else  statement is used in Python for decision making. Here, the program evaluates the test expression  and will execute statement(s) only if the text expression is True . If the text expression is False , the statement(s) is not executed. In Python, the body of the if statement is indicated by the indentation. Body starts with an indentation and the first unindented line marks the end. Python interprets non-zero values as True. None and 0 are interpreted as False Example Of if..else . I
