Arc de Triomphe
Back to index
In case you don't already know, the Arc de Triomphe is a famous monument in
Paris, France. This lesson has everything to do with arcs and not a lot to do
with famous monuments. To kick things off, take a look at this sample program.
<![CDATA[
#!/usr/bin/python
from tkinter import *
master = Tk()
w = Canvas(master, width=300, height=100)
w.pack()
c = ["red","blue","green","purple","yellow","cyan","magenta","orange"]
for x in range(0,8):
w.create_arc(10,10,90,90,start=x*45,extent=45,fill=c[x],style=PIESLICE)
w.create_arc(110,10,190,90,start=0,extent=180,fill="red",style=CHORD)
w.create_arc(110,10,190,90,start=20,extent=140,fill="blue",style=CHORD)
w.create_arc(110,10,190,90,start=40,extent=100,fill="orange",style=CHORD)

You will notice that there are a lot of attributes used with the create_arc
method and there are actually many more than are shown in this sample
program. Take time to sort them out and experiment with them.
ASSIGNMENT:
Write a Python program which creates the following design. Other than one
rectangle to fill in the background color, you may only use the create_arc
method to complete this assignment.
