Does your DOS OS not have the equivalent of xterm, or KDE Konsole, or
such? Something that lets you execute more than just one command, so you
can

Yes. Somewhere or other you've got your tabstop set to 4, and python
treats literal tabs as being of equivalent indent to 8 spaces. As
does my newsreader, so

Here's an exercise I was doing to guess a number from 1-100. Just for
fun (ha ha) I decided to add some error checking too, and now when I run
it, the DOS prompt flashes real quick and disappears. At first, I had
just the top try/except block and not the second one, and that worked

This might help:
import random
number = random.choice(range(1, 100))
tries = 0
while True:
try:
guess = input('Enter a number between 1 and 100: ')
break
except NameError:
print 'Invalid number\n'

Here's another question that is related:
while True:
year = raw_input('Enter year (or other character to quit): ')
try:
year = int(year)
except NameError:
break
if (year % 4
Just barely looked the code answer:
check you scope on the second try block.
if that doesn't work...
I'll read it for real :)
Try PyDev plugin with eclipse - it's served me fairly well, but I did
come from Java - so I'm an eclipse fan already.

Hmm, turns out something was wrong with the indentation of the second

Ha, you found it all before I could fire it up.
The whitespace thing is very odd, and it took about a month before I
was comfortable using it for scope.
On the bright side, scope errors are a lot easier to find than you
might think, once you get used to looking at py code.

I looked at your exercise. As it appears in my browser, there appear
to be a couple of problems with the bottom While block.
0 Alignment problem with the except clause.
As I'm sure you've already discovered, Python is whitespace
sensitive. If it looks like a block, it is; otherwise

Wow, I'm really confused. As it turns out, whitespace *was* the problem,
but it looks no different now (as it works) than it did then (when it
didn't work). I

NP. I appreciate your help. These are just little exercises I found
online, just to give me a reason to use Python. :)
