How to fill my figure with a color in pygame?

Question

A few days ago I've started learning pygame. So, now I've got the code which allows me to draw different curves with the help of a mouse. My task is to fill the curve with a color. I know for sure that the curve is close import pygame as py import sys py.init() White = (255,255,255) Black = (0,0,0) clock = py.time.Clock() H = 400 W = 600 sc = py.display.set_mode((W,H)) sc.fill(White) py.display.set_caption('Curve drawing') py.display.update() draw = False while 1: for i in py.event.get(): if i.type == py.QUIT: py.image.save(sc,r'C:/Users/Xiaomi' + '/temporary.png') py.quit() sys.exit() elif i.type == py.MOUSEBUTTONDOWN: if i.button == 1: draw = True elif i.button == 2: sc.fill(White) py.display.update() elif i.type == py.MOUSEBUTTONUP: if i.button == 1: draw = False if draw == True: py.draw.circle(sc,Black,i.pos,7) py.display.update() Select the correct answer from above options

You could use the PyGame polygon drawing function to create a filled area bounded by all the mouse points. So instead of drawing the circle at each point, keep adding a mouse position to the list of co-ordinates as a mouse moves. When a button is released, draw the filled polygon around all these points. fill_coords = [] # points to make filled polygon while 1: for i in py.event.get(): if i.type == py.QUIT: py.image.save(sc,r'C:/Users/Xiaomi' + '/temporary.png') py.quit() sys.exit() elif i.type == py.MOUSEBUTTONDOWN: if i.button == 1: draw = True fill_coords = [] # restart the polygon elif i.button == 2: sc.fill(White) py.display.update() elif i.type == py.MOUSEBUTTONUP: if i.button == 1: draw = False pygame.draw.polygon( sc, Black, fill_coords ) # filled polygon elif i.type == pygame.MOUSEMOTION: # when the mouse moves if ( draw ): fill_coords.append( i.pos ) # remember co-ordinate mouse_position = pygame.mouse.get_pos() if draw == True: py.draw.circle(sc,Black,i.pos,7) py.display.update() If you are a beginner and want to know more about Python the do check out the python for data science course
