Here is a good starting point if you want to see a variety of ways to
uniquify (?) sequences:

I think it's a little strange and possibly problematic that type(1)
is 'int' and type(True) is 'bool' but
1 == True
specifically evaluates to True even though anything else, even if it
evaluates to True when cast as a boolean, is not == True.
>>> 1 == True
True
>>> 2 == True
False
>>> 0 ==

To use sort(), you'll have

Good catch!
I don't understand it now either.
But I've been up since 4:30am and
I'm trying to think of the best way to go about this one, as the files
I have to sort are *big*.
They're ASCII files with each row consisting of a series of
fixed-length fields, each of which has a corresponding format file.
(To be specific, these files are FirstLogic compatible.)

you're right when you talk about "casting" altho that's not what
python does. it merely performs an object value comparison when you
use '=='. for example, change your code above to:
>>> True == 'i'# because this is what

If they have access to the source code you are right of course.
But typically the source will be in a secure

Not too easily, if the code were distributed as .pycs. However, running
code you read in

I've been trying to learn new things from the Cookbook, but here's a
recipe the utility of which I don't understand at all. Why interpolation

If you mean WAP applications then so far as I'm
aware there is nothing different at the server end
except they serve up some specific XML style

There is another way which is to use enumerate which

I can't figure out how this would ever work at all. It seems like
it's either

This is not a problem, you can distribute a package that includes Python.
