Hi Liam,
Scheme is a recent dialect of Lisp that seems to be well
Hi,
I'm trying to take a list and find all the unique combinations of that list.
I mean:
if I enter (1,2,3,4,5) and I watn combinations of 3, I want to find:
(1,2,3) but then not (2,1,3), (3,1,2),...
(1,2,4)
(1,2,5)
(2,3,5)
(3,4,5)
The thing is, I want to do it as a generic function, where I pas
This question comes up regularly on comp.lang.python. Search the archives for 'combinations' to find
*many* discussions of how to do it. Also there are several recipes in the cookbook.

Why have a decimal.getcontext().prec if it doesn't provide a useful result?
The number of digits in a number is irrelevant to that numbers value.
It just doesn't make sense to me.
I tried quantize the other day and it didn't wo

That is exactly what it is doing. getcontext().prec sets how many digits are used to represent the
mantissa of the number.
Have you taken any physics classes? What is 1000/7 to two significant digits? It is 14
Hi everyone,
Having learnt OOP with C++, and most of my OOP experience being with
Java, I'm used to storing my classes in one file for each class. I find
it tidier and easier to read/debug.
However, when I try to do the same in Python, each file corresponds to
a module with a single class in i
I think this will work:
in foo/__init__.py put
from Bar import Bar
from Baz import Baz
or whatever variations of this you like.
Any names defined in the package __init__.py are available to other code as
package attribute.

Yes at least two of us - DAnny has used Lisp/Scheme.

Lisp by a long long way. Its more mature and has every
bell and whistle going. Of course its much much harder
to become an expert in Lisp for the same re

Just one question...
Why are you off the list?
I see no point.
If you want to stop getting the mail, you can change the options of your

That's the only reason I see...

I have a text file containing 336 records.
I can read and print out the whole file without any problem.
What I want to do is read and print out one record only (chosen at
random). So I need to get to record x, select it, and then print it (or
store it in a variable).
Can anyone tell me now to do

One simple solution is to do:
fle = open(file)
contents = file.readlines()
file.close()
print contents[x] #or store this in a variable, whatever
