Variables — Part 19
Store, update, use in loops. This is part 19 of 20.
What you'll learn
You will learn that variables store values like labeled boxes, and you can read and update them.
Steps
- 1A variable is like a labeled box. Here, 'score' is the label and 0 is what's inside. score = 0 means 'put 0 in the box called score'.
- 2print('Score:', score) looks inside the box and shows what's there — it would display 'Score: 0'.
- 3Then score = score + 1 takes the current value (0), adds 1, and puts the result (1) back in the box. Now score holds 1!
- 4Variables let programs remember and update information — like keeping score in a game, tracking lives, or storing a player's name.
