Wow, that makes this much clearer! I wonder if this behaviour
shouldn't be mentioned in some form in the python docs?

I was able to do this:
import colorsys
sat = 1
value = 1
length = 1000
for x in range(0, length + 1):
hue = x / float(length)
color = list(colorsys.hsv_to_rgb(hue, sat, value))
for x in range(3):

This is nice and simple and has the invertible property that Patrick
mentioned above. Thanks much!

Well, the subject does say python and not
Thanks Patrick, that is what I was exactly looking for.
Paul, thanks for your example. wasn't familiar with the stack class. I
feel Patrick's method is a lot simpler for my purpose.
Regards.

OMG! That's beautiful! I loved the [0]*n how simple and how it never
occurred to me!
Robert I agree with your comment. I feel though that since I'm not
very experienced yet with Python, it's useful to learn about all those
simple yet powerful methods so I can use them when I really need them.

You should use different variables for the two loops.

Actually it is closing the divs that makes it work in FireFox:
import colorsys
sat = 1
value = 1
length = 1000
for h in range(0, length + 1):
hue = h / float(length)
color = list(colorsys.hsv_to_rgb(hue, sat, value

I have a list...
['dir_0_error.dat', 'dir_120_error.dat', 'dir_30_error.dat',
'dir_330_error.dat']
I want to sort it based upon the numerical value only.
Does someone have an elegant solution to this?
Thanks,
Ben R.

a = ['dir_0_error.dat', 'dir_120_error.dat', 'dir_30_error.dat',
'dir_330_error.

How about a one liner?
L.sort(key=lambda s: int
