[Tutor] Help with functions

[mikew@screaminet.com]

One problem I found when I cut and pasted your code was the line that says if choice="as"; it should read if choice=="as". Another line below that is also wrong in the same way. After I fixed that it ran fine for me.

<DIV><FONT size=2>That is my source code so far. I'm following the tutorial at <A href="http://www.honors.montana.edu/~jjc/easytut/easytut/node9.html">http://www.honors.montana.edu/~jjc/easytut/easytut/node9.html</A></FONT></DIV>
<DIV><FONT size=2>and I had a question. Every time I try to get a function to ask for the input of the sides, lenght, width, whatever, it doesn't work. Something funny I found out is that it might work, but then when I quit python and open it again, it doesn't work, saying that ''length' is not defined'. Any thoughts??</FONT></DIV>
