While loop example python, If the condition is True, body of while loopis executed. In Python, we can use the continue statement to stop the current iteration of the while loop and continue with the next one. Constructing a while loop with a dictionary is similar to constructing a while loop with a list. In this example, the condition for while will be True as long as the counter variable (count) is less than 3. 2. Sep 25, 2025 · To learn by solved examples, refer to Python Programs page. number = 2 while number < 9: print (number) number = number + 3 print ("Done!") 2 5 8 Done! The code above starts by initializing that variable number to 2. Inside it, a nested if-elif-else structure evaluates value of y to give more refined control. A while Loop with a Dictionary. Conditional Statement and Loops Problems For loop For Loop 2 While loop Jumping through While Zero Converter The Learn Python While Loops in one video. In Python, we can use the break statement to end a while loop prematurely. Python In computer programming, we use the if statement to run a block of code only when a specific condition is met. You'll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infinite loops. This process continues until the condition is False. z = 0 while z < 3: if z == 0: print("z is",z) z += 1 elif z == 1: print("z is",z) z += 1 else: print("z is",z) z += 1. This tutorial will help you understand loops with easy explanation. Here, 1. Although for loops are preferred when you want to loop over a list, we can also use a while loop for this task. 4. We don’t always know beforehand how many times the code inside a while loop will be executed. Mar 3, 2025 · In this tutorial, you'll learn about indefinite iteration using the Python while loop. Feb 4, 2026 · Learn how to use the Python while loop for repetitive tasks with clear syntax explanations, practical examples, and tips to avoid infinite loops. Let’s go over a simple Python while loop example to understand its structure and functionality: >>> i = 0 >>> while i < 5: >>> print(i) >>> i += 1. Basic Problems Start Coding Learn to Comment Printing Multi Printing Int Str Input For more problems and coding practices visit Python Fundamentals Coding Practice Problem. Once the condition evaluates to False, the loop terminates. Note: remember to increment i, or else the loop will continue forever. However, we need a couple of extra operations because a dictionary is a more complex data structure. When the condition becomes false, the line immediately after the loop in the program is executed. Example of using the break statement in while loops. Dec 23, 2025 · Python While Loop is used to execute a block of statements repeatedly until a given condition is satisfied. A while Loop with a List. Since it is, the body of the . Example: In this example, outer if checks whether x is greater than 5. Tip: We should update the variables used in condition inside Basic Python While Loop. n = 1 while n < 5: print("Hello Pythonista") n = n+1 if n == 3: break. Using if-elif-else statements inside while loop. Using a Counter in a while Loop. The while loop then checks if number is less than 9. In this tutorial, we will learn about Python ifelse statements with the help of examples. Example of using the continue statement in while loops. The while loop evaluates condition, which is a boolean expression. The condition is evaluated again. For better compare difference between pure python while loop and while_loop, there is one test case called pure python while loop with similar logic: cumulative plus 1 for ten times: If you’re new to Python and want to understand how login-style checks work, this short tutorial is a great starting point! 🔑 Keywords Python tutorial, while loop, beginner Python, programming basics, Python input, password program, coding tutorial, Python practice, learn to code, Python logic, control flow 📌 Hashtags #Python #Coding # 4 days ago · CSE 1224: Lecture 2 While Loops We will often need to repeat a block of code multiple times; this can done with a loop. n = 1 while n < 5: print("Hello Pythonista") n = n+1. If you are beginner & earning Python programming, Sep 17, 2025 · Using elif Inside Nested if Statements Using elif within nested if statements in Python allows for more complex decision structures within a branch of another decision. Example of using while loops in Python. The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1. Hence, it’s a good practice to set up a counter inside the loop. If we do, we need to set the while loop condition carefully. Here is an example of a while loop. 3.
