Variables — Part 3
Store a value in a named box. This is part 3 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.
