Thanks to everyone for the answers. I'll definitely check Numeric Python.
Cheers

aList[:] is the shorthand way of taking a copy of aList thus
aList[:][0]
is the same as saying aList[0] except you get a new
Hi Bernard,
You can do this with Numeric (http://numeric.scipy.org/)
import Numeric
aList = [ [1,1,1], [2,2,2,], [3,3,3] ]
bList = Numeric.array(aList, "i")
print bList[:,0]
displays->
[1 2 3]
you can convert the array back to a list if you want like this:
bList.tolist()
so...
result = Numeri
Hello,
I am wondering if can do this:
Let say I have a list of lists. Each individual lists have a bunch of elements.
Now I would like to either get or set the first element of each
individual list. I could do a loop and/or list comprehension, but I
was wondering if it was possible with something
