Now friends, we have another program a very simple but a very smart program this talks about computing the sum of all the numbers from one to a given number. And now here we can see the first line talks about the remark statement program to add all natural numbers from one to n, where n is the input by the user, some is equal to one plus two plus three plus dash dash dash till n. Now be taken input, n is equal to NT input function is being used enter and, and then of course, we initialize the counter on the next line as sum. And I sum is initialized as zero and I is initialized by one we take a while loop while i is less than or equal to n. So of course, initially the value of i is one then of course then gets on added every time the number generated by the loop variable lie is being added till we finish the while loop.

Accordingly, the sum is computed. And finally we display the sum of all natural numbers from one to the entire number is sum. Right. So this is what we conclude here. Now I'll just run it to get to know what it is. We can run it by and it says into n. So here I enter five as a number.

And I get the sum of all numbers from one to the third number is 50. So this is the program and then of course programs finish with exit code zero, press enter to exit, and so on. So I press enter to exit the control. Then I have another option of entering another number say I entered 10. So the loop will go from one to 10. And the sum of all the numbers from one to 10 is printed as 55 in this case, So, this program talks about scenario you can see the use of the while statement the input state input function and together features in this particular program.

Now, friends we have another program is talks about the use of the break statement inside the dough. Now, here we have a variable for variable int string, int Val is equal to i b break otherwise, we need to print the value right. So, when we executed program the value variable will go for S, T and G and as and when it encounters the variable, Val encounters the value I it will break. So, let's see how it goes. The use of the break statement in Python Just expanded it says the first character printed is s then t then R and then the end of the program the end of the program right. So, you can see that the value str is being printed and once the value extracted is I, the control breaks and comes to the outside of the loop for and here this line the print, the end of the program gets executed.

So, this tells us about the use of the break statement and we explore it to the best of learning right. Now, friends, we also understand about the continue statement as we know the use of continuous statement in the loop. condition does not get executed rather it continues the next value in the forum. So, when we have the user continue the program to show the use of continue statement within loops, what actually it does is for Val in boys right, so, the loop will go from VY s, and once the value of y is encountered, it continues to the next increment of the new and this line print value does not come across right. So when we run this, and then of course, we have print the end. So if I run this, you will see the value printed will be B or Y is not printed, because in that case, the control does not go to the print statement, and then S and then the end.

So this is the use of the continue statement inside the loops. And it's so easy, but we need to make sure that we use it As per our logic in our programs
