simple python program using while loop

In most of the computer programming languages, unlike while loops which test the loop condition at the top of the loop, the do-while loop plays a role of control flow statement similar to while loop which executes the block once and repeats the execution of block based on the condition given in the while loop the end.. Syntax of do-while. Create a Python program to print numbers from 1 to 10 using a while loop. Our i variable acts as an index that will CHANGE every time the program runs through the loop. The continue statement is used to tell Python to skip the rest of the statements in the current loop block and to continue to the next iteration of the loop. While loop falls under the category of indefinite iteration.Indefinite iteration means that the number of times the loop is executed isn’t specified explicitly in advance. The condition is true, and again the while loop is executed. If I say In Python, While Loops is used to execute a block of statements repeatedly until a given condition is satisfied.And when the condition becomes false, the line immediately after the loop in the program is executed. A while loop statement in Python programming language repeatedly executes a target statement as long as a given condition is true.. Syntax. How to use "For Loop" In Python, "for loops" are called iterators. When break statement is encountered, the control comes out of the for loop and execute next statement after the loop Features it's fast , because it should be so, together with LLVM's state of the art optimizations, but it won't ever oblige you to make an extra effort from your side just for the sake of performance "continue" stops the current iteration of the loop and starts the next iteration by checking the condition. sum = 0 i = 10 while i > 0 : print "Enter number" num = input () sum = sum + num i = i - 1 print "average is" , sum / 10.0 Write a python program to check given number is prime or not. Just like while loop, "For Loop" is also used to repeat the program. The while loop tells the computer to do something as long as the condition is met. The while loop, like the if statement, includes a boolean expression that evaluates to true or false. While all the ways provide similar basic functionality, they differ in their syntax and condition checking time. The simplest loop in Python is a "while" loop. Here’s what’s happening in this example: n is initially 5.The expression in the while statement header on line 2 is n > 0, which is true, so the loop body executes.Inside the loop body on line 3, n is decremented by 1 to 4, and then printed. To Learn more about working of While Loops read: How To Construct While Loops In Python A Python while loop behaves quite similarly to common English usage. Other than the trick with using a return statement inside of a for loop, all of the loops so far have gone all the way through a specified list. The while loop has two variants, while and do-while, but Python supports only the former. Implementing Fibonacci sequence in Python programming language is the easiest! Python Program to implement Fibonacci Sequence. Now, let’s see how for loop works when else, break, continue, and try statements are used. while expression: statement(s) Here, statement(s) may be a single statement or a block of statements with uniform indent. But, how does it work? When the body of the loop has finished, program execution returns to the top of the loop at line 2, and the expression is evaluated again. This is beneficial as you will use nested loops and understand to master loop for better coding. As usual, you are free to use else-statement with if-statement. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).. Loop through each element of Python List, Tuple and Dictionary to get print its elements. Take 10 integers from keyboard using loop and print their average value on the screen. for i in range(1,10): if i == 3: continue print i While Loop. One key thing to be noted is that the while loop is entry controlled, which means the loop can never run and the while loop is skipped if the initial test returns FALSE.. For example, following code inside the while loop will be never executed because the initial test will return FALSE.. i = 5 while (i > 8): print ('This is while loop') i++ In this tutorial, learn how to use while loop in Python. So we need a loop that divides our input number by our index i. i will increase while it is one less than our number. "break" shouldn't be confused with the continue statement. This repeats until the condition becomes false. The loop continues as long as the specified logical expression is true (note the obligatory indentation): while x < 23: x = x + vx*dt. A "While" Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. With the help of a break statement a while loop can be left prematurely, i.e. The condition may be any expression, and true is any non-zero value. For and while are the two main loops in Python. while i
