Iteration

Iteration allows computer programmers to:

-write one set of instructions that operates on many sets of data, saving time and resources. -execute the programming loop repeatedly while records are read automatically. -identify errors in coding logic or in entered data.

iteration

Iteration means repetition. In computer programming, it refers to a situation in which a set of instructions can be run multiple times throughout the program.

pass statement

a Python exit statement that is used when the programmer does not want any code to execute but wants to keep that place in the code for future development. It is often used as a placeholder for future code.

continue statement

a Python exiting loop that returns to the beginning of the loop. It works by rejecting the remaining statements in the current iteration of the loop and moving back to the top of the loop.

sequence index

a Python loop statement that uses a built-in function called length, or len(). It provides the total number of elements in the ordered list of elements, as well as the range. It is used as an alternative to iterating through each item.

while loop

a looping construct that is available in the Python programming code language. The while loop continues to repeat until the expression becomes false.

loop statement

a statement that causes a section of code to be repeated a certain number of times. The repetition will continue as long as the condition in the code is true.

infinite loop

also referred to as an endless or continuous loop, is a loop statement that provides continuous repetition. The computer will continue performing the action indefinitely, because the statement condition never resolves to false.

for loop

can iterate over many items in any list or sequence. It is used to repeat a piece of code a set number of times.

Single-statement suites

similar to If statements. In this type of loop statement, the code is placed on one line. Single-statement suites are useful for programmers because they allow programs to be smaller.

break statement

stops the current loop, then resumes execution at the next statement. Programmers use break statements when an external condition has been triggered and an immediate exit from the loop is required

loop

when the sequence is executed multiple times
