Many programs need to repeat actions. Instead of copying the same code again and again, Python gives you loops to repeat code automatically.
You can think of a loop as telling the computer:
“Do this block of code again and again, until I say stop.”
Loops help you:
- Avoid writing the same code many times
- Process many pieces of data (like all items in a list)
- Build interactive programs (like games) that keep running
- Automate repetitive tasks
In this chapter, you’ll work with two main types of loops in Python:
whileloopsforloops
You’ll also see how to control loops using break and continue, and how to count with loops.
