Stop Repeating Yourself: Mastering Loops in Programming

Imagine you need to print 'Hello!' 1 000 times on screen. Would you really type the same line of code one thousand times? That would take hours — and if you spotted a typo, you'd need to fix every single copy. There has to be a smarter way. Think about everyday life: a washing machine runs its drum round and round until the cycle ends. A traffic light repeats its colour sequence all day. Repetition is everywhere — and programmers have a powerful tool to handle it elegantly: the loop.
