Python while loop code#
Because neither of the conditions in the parentheses are met, the code stops executing. The syntax of the while loop is very similar to the if statement, as you can see above. The break statement executes the current loop.
However, as opposed to the if statement, the while loop continues to execute the code repeatedly as long as the condition is True. Python while loop break and continue In Python, there are two statements that can easily handle the situation and control the flow of a loop. A while loop performs a set of instructions as long as a given condition is true. The reason for this a is less than 4 and b is greater than 3 after the third iteration. The while loop is somewhat similar to an if statement, it executes the code inside, if the condition is True. The else block is executed when the looping condition becomes false. A condition to determine if the loop will continue running or not based on its truth value (True or. This is the basic syntax: While Loop (Syntax) These are the main elements (in order): The while keyword (followed by a space). We can see here that the code stops after the third iteration. You can use an else statement in a while loop. Now you know how while loops work, so let's dive into the code and see how you can write a while loop in Python.
Python while loop how to#
In this tutorial, we will learn how to use while loop to traverse through the elements of a given list.
# Hello! The value of a is 6, the value of b is 4, and the value of c is 7. While loop can be used to execute a set of statements for each of the element in the list. # Hello! The value of a is 3, the value of b is 7, and the value of c is 6. # Hello! The value of a is 0, the value of b is 10, and the value of c is 5. To see how we can stop a while loop in Python, let’s take a look at the example below: a = 0 Because of this, we need to be careful about executing a while loop. While loop inside another while loop is called Nested While Loop. However, if the expression is false, the loop ends. If it’s still true, PHP executes the statement again. Then, PHP re-evaluates the expression again. If the result is true, PHP executes the statement. As you already know that while loop body can contain statements, we can write while loop inside while loop. The syntax of the while statement is as follows: How it works. The program would run indefinitely, until the condition is not longer True. Python Nested While Loop Python While Loop is just another Python statement. In the example above, the while loop will complete the step do something indefinitely, until the condition is no longer met. Let’s take a quick look at how a while loop is written in Python: while :
A Python while loop is both an example of definite iteration, meaning that it iterates a definite number of times, and an example of indefinite iteration, meaning that it iterates an indefinite number of times. The condition for the do/while loop is evaluated at the end of the loop. A while loop is similar to a Python for loop, but it is executed different. How to Group Multiple Conditions in a Python While LoopĪ Python while loop is an example of iteration, meaning that some Python statement is executed a certain number of times or while a condition is true.Using a NOT Operator in a Python While Loop with Multiple Conditions.Print i as long as i is less than 6: i 1 while i <. If the number of iterations (repetitions) you. Python While Loop with Multiple Conditions Using OR With the while loop we can execute a set of statements as long as a condition is true. The While loop is used to iterate (repeat) part of the program several times.
