Lesson Outcomes
After completing this practical lesson, learners will be able to:
- Explain loops in programming
- Create and execute loops
- Use counting and conditional loops
- Process repeated tasks using loops
- Control loop execution
- Test and debug loop structures
Overview
Loops allow programs to repeat instructions automatically until a condition is met. Loops are essential in software development and Robotic Process Automation (RPA) environments because they automate repetitive tasks and improve processing efficiency.
This practical lesson introduces learners to loop structures, repeated execution, loop control, counters, and iteration within programming environments. Learners will complete practical activities involving automated repetition and data processing using loops.
Scenario: Automated Attendance Processing System
A software development company is building a system that processes daily learner attendance records automatically.
The system must repeatedly process learner records until all entries have been completed.
Learners are required to create and execute loops that automate repeated processing tasks.
