While loop python

In this Python While Loop lesson, we will learn how to use one of the important loop statements of python with different examples.

Learn while loop in Python with example program, syntax of while loop statement, flowchart of while loop, how does while loop work in Python

In this tutorial, you'll learn about indefinite iteration using the Python while loop. 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.

Here in this post, you will learn about Python loops. 1. Python has two primitive loop commands: while loops for loops 2. With the while loop we can execute a set of statements as long as a condition is true. 3. With the break statement we can stop the loop even if the while condition is true. 4. With the continue statement we can stop the current iteration, and continue with the next. 5. With the else statement we can run a block of code once when the condition no longer is true.

for loop is used to perform repetition (or iteration) over the block of code as long as the condition is true...

A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Similarly to while loop, a for loop can also use the key words: break, continue, else. To loop through a set of code a specified number of times, we can use the range() function.
