Python. PyGame.

Draw module

Draw Line

pygame.draw.line(screen, color, (x0, y0), (x1, y1), width)

screen - surface
color - color
(x0, y0) - the start of the line
(x1, y1) - end of line
width - width of the line

Draw Lines

pygame.draw.lines(screen, color, bool, [(x0, y0), (x1, y1), (x2, x2), ..., (xn, yn)], width)

screen - surface
color - color
bool - if True draw a line between the first and last points in the sequence of the points
[points] - points connected in series
width - width of the line

Draw Polygon

pygame.draw.polygon(surface, color, [points], width=0)

screen - surface
color - color
[points] - points connected in series
width - width of the line

Draw Rectangle

pygame.draw.rect(screen, color, (x0, y0, width, height), border)screen - surface
color - fill color
(x0, y0, width, height) - coordinates of the upper left corner of the rectangle, the width of the rectangle, the height of the rectangle
border - the width of the border of the rectangle, with a value of 0, a filled rectangle is drawn

Draw Circle

pygame.draw.circle(screen, color, (x, y), R, border)screen – surface (поверхность)
color – fill color
(x, y) – координаты центра окружности
R – радиус окружности
border - the width of the border of the circle, with a value of 0, a filled circle is drawn

Draw Ellipse

pygame.draw.ellipse(screen, color, [x0, y0, width, height], width)

screen – surface (поверхность)
color – fill color
[x0, y0, width, height] – coordinates of the rectangle
border - the width of the border of the rectangle, with a value of 0, a filled rectangle is drawn

Draw Arc

pygame.draw.arc(screen, color, [x0, y0, width, height], start_angle, end_angle, width)

screen – surface 
color – fill color
[x0, y0, width, height] – coordinates of the rectangle
start_angle (float) - start angle of the arc in radians
stop_angle (float) - stop angle of the arc in radians
width - width of the line

Example of programs

import pygame
pygame.init()
size = width, height = 400, 300
screen = pygame.display.set_mode(size)
pi=3.14
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    pygame.draw.arc(screen, (255, 255, 0), [100, 100, 200, 120],0, pi)
    for i in range(5):
        pygame.draw.arc(screen, (255, 255, 0), [100+40*i, 150, 40, 24],0, pi)
    pygame.draw.line(screen, (255,255,0), (200, 150), (200, 200), 1)
    pygame.draw.arc(screen, (255, 255, 0), [177, 189, 25, 25], pi, 2*pi)
    pygame.display.flip()
pygame.quit()
