Explanation In the above code we use nested loops to print the value of i multiple times in each row, where the number of times it prints i increases with each iteration of the outer loop. The print function prints the value of i and moves to the next line after each row. Loop Control Statements. Loop control statements change execution from their normal sequence.

Post-test loops nothing in python C, C, Java has the do-while loop-Evaluates the Boolean expression after executing the body.-Guaranteed to execute at least once.-Execute one or more times.-Structure do Body while BE James Tam Examples Pre Vs. Post Test Loops Java - For Illustration Only Pre-test age 0

The pre-test loop structure is shown in the following flowchart. Let's see what happens when the flow of execution reaches a pre-test loop structure. If Boolean_Expression evaluates to True , the statement or block of statements of the structure is executed and the flow of execution goes back to check Boolean_Expression once more.

Learn how to implement post-test loops, loop-and-a-half, and Boolean decisions in Python in 5 minutes! Watch now to explore key techniques and examples, then take a quiz.

post-test loop. A loop that executes the body, then tests for the exit condition. We don't have a special Python construct for this, but can use while and break together. pre-test loop. A loop that tests before deciding whether the execute its body. for and while are both pre-test loops. single-step

If Your question is regarding, when you are solving the problem on competitive places like hackerrank or anywhere else. If they have not provided their environment to run test cases in a loop. And locally if You are running code for python compiler It would be useful. you can simply use a while loop or range function of python. e.g

Pre-test loops You want to execute the body of the loop before checking the stopping condition typically used to ensure that the body of the loop will execute at least once. The logic can be simulated in Python however. Post-test None in Python A 'counting loop' You want a simple loop to count up or down a certain number of times
