problem with the colours module

i am trying the table_demo.py on IDLE and i am getting this

    > error message: Traceback (most recent call last): File
    > "C:\Python23\practices\table.py", line 5, in -toplevel- from
    > colours import get_colours ImportError: No module named
    > colours

You have to download the examples directory which contains
table_demo.py -- it is available as a zip file at
http://matplotlib.sourceforge.net/matplotlib_examples_0.72.zip

This dir contains colours.py, which table_demo imports.
