Add Initialized Gender with airSlate SignNow

Add initialized gender

okay welcome to our video tutorial so in this video tutorial we will see how to implement the object-oriented concepts have discussed in the previous video using python syntax of course so let's try to create a simple class so let's have a new file new python file let's call it create class okay so let's create a person class so the syntax is we have a pure class and then the class name so the class name is person and what person has as its property is going to be initialized or we're going to create an initialize a function the this initializer function what this initializer function is going to do is it's going to assign values to our class properties or attributes that are going to be provided when this person class is being used or where when whenever we create an instance of this class okay so the function for initializing our at our class attributes is called an initializer function how are we going to define that initializer function the syntax is very simple define or div two underscores in its two underscores again now we write self in the inferences : now here is our definition or our code for our class person what this self means this class tries to access whenever this class tries to access its own attributes it uses self as a keyword in other programming language like Java we use these attributes or this keyword yeah in case of Python we use self now we need other parameters for our person class what are those the first thing full name any person has a full name any person will have age gender and other attributes like country now we are creating an initializer function and this initializer function accepts four parameters from the user and one parameter for itself okay self function is a different parameter we're not going to accept this input from users only we only require users who who need to create our instance our class instance we expect them to provide four parameters because whenever they try to create a person each person should have these four parameters so after accepting those parameters we have to assign those parameters to our self class to our class this self represents the self creates it instance of our class so when we say some dots full name equal to full name this full name means the input parameter we have received self dots H equals H self dots we can reverse the order doesn't matter as long as we wrote the spelling correctly okay so this is our initializer function now we are done we have defined our very first class our class name is person okay and we have a parameter or we have attributes who have four attributes for this person for this person class those attributes are full name age country and gender and also we have initialized those class attributes with input parameters to be provided from user now let's try to create our let's try to create an instance of our class okay let's say we have we need we created person 1 so person 1 is going to be from % class and this % class requires 4 parameters okay as you can see since I am using Python as a Python IDE it provides intellisense for me what are the parameters being expected by the person class as you can see we have to require we have to provide age country full name and gender so the first parameter has to be full name we have to provide them in order self is not going to be provided I'm not going to provide the self attributes okay self is being provided by price and itself so I'm going to start from full name full name is Amit Gupta age 30 gender male country India okay so now I have created a new class and initialized this class with 4 parameters now I can print person one dots full name now let's run our projects let's run our code and see what will happen so person 1 dot full name is Amit Gupta person 1 dots let's try to see country person 1 dots country let's run it so Amit Gupta country India so what we achieved here is it's a simple example but the ramification is huge what we can do here is we have defined one simple class and we can create as many instances as we can or as we want okay like have you ever played or seen people playing soccer I mean video game like what's the name FIFA okay actually I stopped playing fifa 5 in 2005 I guess but what they did is I don't really know the internal code but using object-oriented we can create one simple player class and that simple player class will have a name playing position club which club he or she is going to play country and other parameters even the the uniform the way the web when they play so they only creates one class let's say player class and then they have the double crates as many number of instances as they want let's say for one game if we need 22 players 11 for one team and 11 for the other team so they which means they create 22 instances of one player class so the the application of this object-oriented concept is very huge and I'm sure you are going to use it a very sophisticated projects as well so this is just a simple presentation we have seen how to declare our function and how to define our initialize function and also how to create an instance of a class and how to access the values or the attributes of a created instance so this is what we achieve in this video in the next video we'll see how to define functions in our class and how to access those funds or how to call those functions as well so we call those functions methods when we create functions inside a class we call them methods like when we create variables inside a class we call them attributes right so when we create functions inside a class we call them methods and in the next video we'll see how to implement that so thank you for watching I hope it's clear if you have any questions comments or suggestions of any kind please write it in the comment section below and we'll respond as much as possible as quick as possible ok so thank you for watching
