Python While Loop

About While Loop

In Karel, a while loop is used to repeat a body of code as long as a given condition holds. The while loop has the following general form while test statements to be repeated. The control-flow of a while loop is as follows. When the program hits a while loop it starts repeating a process where it first checks if the test passes, and if so

In the first loop, Karel arrives to the last square. In the second loop, Karel takes the balls. In the third loop, Karel returns to the starting square. In the last loop, Karl leaves all the balls he has with him. Of course, after the first or the second loop, Karel should turn towards the starting square twice to the left or twice to the right.

In the while loop, the loop update i 1 happens in Python, whereas in the for loop again the iterator of range100000000, written in C, does the i1 or i. We can see that it is a combination of both of these things that makes the for loop faster by manually adding them back to see the difference.

While Loops in Karel Repeating Karel Actions. We've already learned that we can repeat Karel actions with a for loop. What if we want to move all the way to a wall? In this case, since we don't know how long the world is, we can't put a fixed number in the loop. Is there another type of loop that can handle repeating code when we don't know how

Python While Loops Previous Next Python Loops. Python has two primitive loop commands while loops for loops The while Loop. With the while loop we can execute a set of statements as long as a condition is true. Example. Print i as long as i is less than 6 i 1 while i 6 printi i 1

Loops Remember that commands in a loop statement must be indented one level. While Loops while CONDITION Code that will run while the CONDITION is true. Once the CONDITION is no longer true, it will stop. Example of while loops This moves Karel to a wall while front_is_clear move For Loops

There are three types of loops repeat, while, and for-in. The repeat loop is used when the number of repetitions is known in advance repeat 5 go The while loop should be used when we do not know in advance how many repetitions will be needed while not wall go If we want to iterate over every element of a given sequence, it is convenient to

Example of Python While Loop Python. cnt 0 while cnt lt 3 cnt cnt 1 print quotHello Geekquot Output Hello Geek Hello Geek Hello Geek Using else statement with While Loop in Python. Else clause is only executed when our while condition becomes false. If we break out of the loop or if an exception is raised then it won't be executed.

Introduction. In the world of programming, loops play a crucial role in automating tasks and iterating through data. One of the most versatile and widely used loops in Python is the while loop. In
