Read the section on sequence slicing in the Library Reference. Use the
interactive interpreter or IDLE to perform experiments, like you did,
until you understand to your satisfaction.

The slice [0:2] represent positions 0 <= x < 2
Replaces the [1, 2] from [1, 2, 3, 4] with ['a', 'b']
Result: a = ['a', 'b', 3, 4]
>>>b[2:4] = a[2:4]
The slice [2:4] represent positions 2 <= x < 4
Replaces the ['c', 'd'] from ['a', 'b', 'c', 'd'] with [3, 4]

I do not understand why python behaves the way it does
in the following code:
Here, Python doesn't like that I'm assigning
out-of-range. OK. That's fine.

Hi all!
I'm new to Python and just tried to assign values to a portion
of a string, but I don't get it.
My code is:
bits = '\3ff' * bmi.bmiHeader.biSizeImage
ofs = 0x1E2C0
for i in range(0, height):
bits = self.shbits

After considering several alternatives and trying out a few ideas with a
modified list object Bengt Richter posted, (Thank You), I think I've
found a way to make slice operation (especially far end indexing)
symmetrical and more consistent.
So to find out if this is indeed a possibility, it would be nice to get
a few opinions at this point. So blast away... or hopefully tell me
what you like about it instead. ;-)

I am trying to pass a slice from a larger 2-dimensional array to a
function that will work on a smaller region of the array space. The
code below is a distillation of what I am trying to accomplish.

Now slices are objects in python, I was wondering if slice

Will it ever be possible to write things like:

It seems to me that the indices() method for slices is could be
improved. Right now it gives back concrete indices for a range of
length n. That is, it does not return any None values. Using an example
from clpy about this the indices for a 'None, None, -2' slice for a
range of length 10 are given as '9, -1, -2'. The problem is that these
concrete values cannot be fed back into a slice so that a slice will
extract the same elements that...

Hey all. I've decided I let my Python skills (minor though they were)
slip away so I started reading the new edition of Learning Python to

could explain what's going on under the hood that makes index and slice
assignments behave differently when assigning an empty list.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
