Demo scripts
|
||||
============
|
||||
|
||||
There is a set of demo scripts in the turtledemo directory located in the
|
||||
:file:`Demo/turtle` directory in the source distribution.
|
||||
There is a set of demo scripts in the :mod:`turtledemo` package. These
|
||||
scripts can be run and viewed using the supplied demo viewer as follows::
|
||||
|
||||
It contains:
|
||||
python -m turtledemo
|
||||
|
||||
Alternatively, you can run the demo scripts individually. For example,
|
||||
|
||||
::
|
||||
python -m turtledemo.bytedesign
|
||||
|
||||
The :mod:`turtledemo` package directory contains:
|
||||
|
||||
- a set of 15 demo scripts demonstrating different features of the new module
|
||||
:mod:`turtle`
|
||||
- a demo viewer :file:`turtleDemo.py` which can be used to view the sourcecode
|
||||
:mod:`turtle`;
|
||||
- a demo viewer :file:`__main__.py` which can be used to view the sourcecode
|
||||
of the scripts and run them at the same time. 14 of the examples can be
|
||||
accessed via the Examples menu; all of them can also be run standalone.
|
||||
- The example :file:`turtledemo_two_canvases.py` demonstrates the simultaneous
|
||||
- The example :mod:`turtledemo.two_canvases` demonstrates the simultaneous
|
||||
use of two canvases with the turtle module. Therefore it only can be run
|
||||
standalone.
|
||||
- There is a :file:`turtle.cfg` file in this directory, which also serves as an
|
||||
