#15 For loop in Python || Python Tutorial for Beginner

Key Takeaways

hello everyone welcome back to my channel code for kids so today we will learn about for loop in python okay before that i want to inform you one thing one good news in our channel uh i started machine learning project for the kids even you can access that playlist also like uh here we need to first you have to go to our channel like uh code for kids okay this is our channel over here if you will go to the channel playlist you will get our new playlist which is machine learning so you can access this one is okay so let's start our python for loops so first thing we have to search our google collab for python we need to access that and here we have to just click on create new notebook okay so what will happen in that notebook we can do our project click on new notebook so first thing i will explain you what is python for low okay so see first thing why we are using the low so if you want to access anything see we have list we have tuple we have dictionary we have set we have strings so if you want to access all these data so we have one method which is for loop so with the help of our for loop we can iterate all this thing and we can access the data so we can say a for loop is used for iterating over a sequence the sequence can be your list or it can be the tuple or dictionary or dictionary or set or anything okay so now we will see the next part so we can say the for loop is just a keyword like in any other programming language and it work more like an iterator method we can see okay and this is this follow we are using in our object oriented programming language okay so now we will receive an example suppose we have one variable which is animal here we have some values like first see i like dog so i will write dog then we have cat and we have one more animal which is like you can write your favorite animal name i want to write elephant okay after that if you want to access this item what we can do in the for low we can take one variable name suppose for x in you have to write in keyword and what is our variable name here we have animal right you need to take your colon now you can just print x okay so by using your print method we can print anything so here you need to write your variable name now what will happen if i will run this project so you can just stop this video in the comment section write your output okay so what output you will get here you will get dog cat elephants whatever value we declare here you will get the same value okay now we will see the next part suppose if you want to use the break statement here okay what we have to do so i'm little bit lazy so i will copy this code you can take a plus sign here so you will get one more section here in a same program i want to add one condition if x is equal to equal to if i have here talk so what will happen i want to break this okay now if you will run so what output you will get here so here we have to just take one space because so here see if x is equal to equal to dot we need to break means it will not print your further value but if i will write cat here so what will happen it will print your dog and cat as well after the cat whatever we have here it will eliminate that value so this is called as break statement okay so we can say with the help of our break statement we can stop the loop before it has looped through all the items okay so that's why we are using the break statement now we can see the next one which is our continue statement so again i will take one plus code section here and you can use our same example like a in the animal variable we have some values so now we have to add one condition if x equals to equals to the cat so i want to continue if x is equal to equal to cat so i want to continue here so you have to use your continue keyboard and then i want to print my x print and you need to print your value suppose i want to print the x so what will happen now yes suppose i don't want to print here this value and if x equals to equals to cat okay i want to continue first and then we want to print the value okay so now we will see what output you will get here see what you will get here if x equals to equals to cat we need to continue this now here we have to pay so what will happen it will in eliminate this value like your cat value now you will get dog and elephant okay now what will happen if i will write dog here instead of cat if i will write dog and if you will run this so you will get cat and elephant because we have to continue this okay now after that we can use our range function okay so why we are using the range suppose if you want to print anything in a sequence so we can say the range function written as a sequence of number like a starting from by default we have a zero value and it will increment by one by default and whatever number you will specify here that is your last number suppose i want to just write for x in range so range is our inbuilt function here i want to pass the value 6 okay now you need to just print this x so print x now see what will happen what output you will get here run this project you will get see it will start from 0 till 5 because we have a range like a 0 to 6 so in this way we can use our for loop even we can use our else part here suppose if for x in range 6 we need to print x else i want to print we can write any statement like i want to print finished so we can write finished now if i will run this program you will get first your wrench in a spot you will get a finished so in this way we can use our for loop okay so please like share
