I have the local machine's administration privilege.

When I run the command as you point out, I got the following
messages

The process itself needs to have the privilege. This message has complete

You mean é? Oh, it is perfectly printable. It's even on my
keyboard (as unshifted 2), along with è, ç, à and ù. Ah, American
cultural assumption... ^^
From the email address, chances are that this was a New Zealand cultural
assumption. Ah, the French, lumping all English speakers under

Did you mean hexadecimal?
Sigh. Yes. I did a one character typo. Please forgive me.

Does anyone know if there are some *beginner*-user-friendly tutorials
out there for pickle? Or can give a sample of how you would implement
it into a VERY SIMPLE program? Obviously I can get to the import
pickle step, but once I'm past that, I'm totally lost!
There's the example in the
In the print word [::-1] line it gives me this message

As others have said, it means you're using Python 2.2 or older (so can't use
extended slicing). It seems likely that what you're after is the loop
approach that has been mentioned by
I have read about loops, strings, tuples. I am taking this
class on distance education and I am lost with this
assignment. I have read what Tony has wrote and that does me
no good. I do not understand what he is talking about.
Which bits? The whole lot? I teach university students
Is there a reason to prefer one over the other? Is one
faster? I compiled my regular expression to make it quicker.
With Python 2.4 I get these results (all imports are factored out, all give
the same result except for CSV which strips the s) with timeit.py:

What's b.index(x) do?
I'm guessing the for a list Delta = [a,b,c], you get
Delta.index(b)
1
Am I right?
Yes. For future use, the easiest way to answer a question like that is to
do:
help([].index)
Help on built-in function index:
index(...)

Hey I am new at python and i am trying to learn about
it. I was wondering if you could tell me how to write
a range to 100. such as 1+2+3+4+5 ect. without
writing it out.
Do you want a container with a range in it, like the list
[1,2,3,4,5,...,100]:
range(100)
[0, 1, 2, 3, 4, 5, 6, 7,

Does anyone know of any online resource that explains how to
interface to Microsoft Access via Python, where the intended
audience is someone who knows Python, but not the Microsoft innards?

Is there a better way for raw_input to accept both caps and
lower case letters than:
[...]
if action == 'y' or action == 'Y':
if action in 'yY':
dostuff()

Although, that does mean that if a user enters 'nN' they'll
get no, but that shouldn't be a huge problem, and it it does,
def approachB(files):
isHTML = [filename if filename.endswith('.htm') or\
filename.endswith(.html') for filename in files]
return isHTML
No, it should be...
isHTML = [filename for filename in files if
filename.endswith('.htm') or\
filename.endswith('.html') for filename in
I'm trying to write a program they may involve
needing to divide 1 by another number. In the
program below when I use 4 for the diameter of
the bore, and 1 for the diameter of the rod,
and 60 for the PSI, the force should be 706.8 .
However the program keeps giving me 0 for rodarea.
If I
In that case you need it to use floating point numbers.
The easiest way is to use 1.0 but if it comes from a table
or user entry you might have to explicitly convert:
one = 1
other = 42
result = float(one/other)
What Alan meant, presumably, was this:
one = 1
other = 42
result =

I'm curious about good tutorial websites and books to buy.

I learned Python (well, the basics thereof -- enough to do useful
stuff on my summer job, anyway ^^) in an afternoon using the official

import decimal
decimal.getcontext().prec = 2
a = decimal.Decimal(2)
b = decimal.Decimal(3)
100*a/b
Decimal(67)
print 100*a/b
This prints 67.
try -
a=decimal.Decimal(2.0)
This will not work. You can't convert a float directly to a decimal.Decimal
