Note that once the above if fails such that the below elif is tested, 
you already know that curraverage>= 90 from the if above failed, so

on the elif below you really don't need to test if curraverage < 90.


 elif curraverage >= 80 and curraverage < 90:
 grade= "B"
 lettergrades.append(grade)
 elif curraverage >= 70 and curraverage < 80:
 grade= "C"
 lettergrades.append(grade)
 elif curraverage < 70:
 grade= "F"
 lettergrades.append(grade)


You can also move the lettergrades.append(grade) outside the if tests.

Combining both simplifies this to:

if curraverage>= 90: grade="A"
elif curraverage >= 80: grade = "B"
elif curraverage >= 70: grade = "C"
elif curraverage >= 60: grade = "D"
else: grade = "F"
lettergrades.append(grade)

HTH,

... reading through the rest of this thread... I'm surprised no one
has mentioned:

 http://www.codecademy.com/tracks/python


Depending on your child's level, you might even look at Scratch:

http://scratch.mit.edu/

which is not Python at all, but it is programming, and it is very much
focused on the beginner experience.

  I am considering purchasing the Acer c720 chromebook for my 13yo to
begin learning Python for Kids. Obviously I am on a budget.

Is this a good choice for a complete beginner? Any particular challenges
that she might encounter using a chromebook OS?

Any advice would be greatly appreciated. As I have researched my way into
confusion.



Hi Colin,

Ok, I read this question a little more carefully.

You're planning to use the book "Python for Kids", right?

 http://shop.oreilly.com/product/9781593274078.do

If using that book is a requirement, then I have to take back what I said
about web environments being appropriate for this particular situation.


That book requires a computer running either Windows, Mac OS X, or Linux.
  It will have some exercises that assume that it can have graphical control
over the desktop with the "Tk" graphics library, a capability that you will
not likely have in a web-based environment.

Apologies for not reading the requirements more closely.  I saw "learning
Python for kids", and did not think that you were referring to a specific
book!  :P

If you don't *need* Windows, there is no point in running Linux on top
of Windows in a virtual machine. It just means you're using twice as
much memory, and you are still bound by the stability of Windows.


Right. I repartitioned my drive,  shrank the installed Windows
  partition to a minimum,  and installed linux as a dual boot. If I
  really need a Windows program,  I run it in a Virtual box with
  XP.
