Numworks: Text Demos with a Poem and Rolling Screen Credits
The two scripts, which developed in Numworks:
nwtext1.py: Displaying a poem one line at a time.
nwtext2d.py: Presenting the credits in a classic TV show format.

Display a Poem: newtext.py
Code:
# nwtext1.py
# Text Animation Demo 1
# Numworks
# Edward Shore, 2/18/2026
# import modules
from math import *
from kandinsky import *
from time import *
# Screen: 320 x 220 pixels
# list of text
t=['Roses are red','violets are blue','Nuwmorks is great','and so are you!']
# list of colors: red, violet, amber, ghost white
c=[(255,0,0),(178,0,237),(255,191,0),(245,245,245)]
# black background
fill_rect(0,0,320,220,(0,0,0))
# list the text
# each line is 20 pixels
for i in range(len(t)):
# draw the string for each line
# must include the black background
# draw_string assumes white background if second color
# is left off
draw_string(t[i],60,60+20*i,c[i],(0,0,0))
# time module's sleep
sleep(1)
Notes:
1. Modules used: math, kandinsky, time. Math was entered by default every time a new script is started in Numworks. The kandinsky and time modules are specific to Numworks. The kandinsky module includes the drawing commands fill_rec and draw_string while the time module has the command sleep.
2. The line fill_rect(0,0,320,220,(0,0,0)) gives the drawing screen a black background.
3. The syntax for kandinsky’s draw_string is: draw_string(string of text, x y, text color, background color). The colors are optional, with the default set at black text color and white background. Since we have a black background for the entire screen, the background color (0,0,0) must be included.
4. To give readability I estimate that each line has a height of 20 pixels.
TV Screen Credits: nwtext2d.py
Code:
# nwtext2d.py
# Text Animation Demo 2
# Numworks
# Edward Shore, 2/19/2026
# Goal: give a classic TV style flashing of credits
# import modules
from math import *
from kandinsky import *
from time import *
# Screen: 320 x 220 pixels
# lists of text
# I'm not going to worry about center justification on this demo
# unicode for pi is u\03C0
# top line
t0=['CREDITS','Programmer','Supervisor','Directed By','Studio','Written By','A Pisces','']
# bottom line
t1=['','PI MAN','MS. SQUARE ROOT','PYTHAGOREAN THEOREM','SINE STUDIOS','PI MAN','Python Production 2026',':) \u03C0']
# black background in the loop, see comments
# roll credits
# each line is 20 pixels
for i in range(len(t0)):
# draw a string for each line
# text is in emerald green
# background is black, must be included
# since text is being replaced, we must refresh the screen every time
fill_rect(0,0,320,220,(0,0,0))
draw_string(t0[i],40,60,(80,200,120),(0,0,0))
draw_string(t1[i],40,100,(80,200,120),(0,0,0))
# delay by 2 seconds
sleep(2)

4. In attempt to vertically center the credits, I put the top line at y = 60 and the bottom line at y = 100. In this demo, I did not worry about center justification, only choosing to left justify all the lines. The strings for the top line are stored in the list t0 while the strings for the bottom line are stored in the list t1.
I hope you enjoy these programs as I did making them,
Eddie
