Use RGB color tuples correctlyDraw lines, circles, rects, ellipses and polygonsControl filled vs outline shapes with widthExplain the fill/draw/flip frame order📚 Quick Recap
Pygame draws with plain RGB tuples and a handful of pygame.draw functions — lines, circles, rectangles, ellipses, polygons and arcs — each following the same width=0-means-filled convention, and nothing is visible until display.flip() runs.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1What does width=0 mean in a pygame.draw call?
2What must run before any drawing each frame?
3What shape does pygame.draw.ellipse make from a square rect?
4What units does pygame.draw.arc use for its angles?
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5An RGB color tuple has numbers, each from 0-255.
6pygame.draw.polygon takes a list of that it connects in order.
7Write the pygame.draw call to draw a filled red (220,20,60) circle at (400,300) with radius 40.
8What's the difference between pygame.draw.rect(...,0) and pygame.draw.rect(...,3)?
9Name the function that finally makes your drawings appear in the window.
🚀 Section C · Challenge ● CHALLENGE 5
10If you forget screen.fill() every frame, what visual artifact appears on screen as sprites move, and why does it happen?

1-B 2-B 3-B 4-B | 5 three 6 points (x,y) 7 = pygame.draw.circle(screen,(220,20,60),(400,300),40) 8 = width=0 fills the rect solid; width=3 draws only a 3-pixel outline 9 = pygame.display.flip() (or pygame.display.update()) | 10 = old frames "smear" across the screen because nothing erases the previous drawing before the new one is drawn on top of it
