<h3>Try This</h3>
<form>
<textarea id=”yourcode” cols=”40″ rows=”10″>import turtle

t = turtle.Turtle()
t.forward(100)

print “Hello World”
</textarea>

<button type=”button” onclick=”runit()”>Run</button>
</form>
<pre id=”output” ></pre>
<!– If you want turtle graphics include a canvas –>
<div id=”mycanvas”></div>

</body>
