Isn't there an easier way than
lst[len(lst) - 1] = ...
?
57  41873 
Or alternatively:
Is there a way to make reference to the last element of a list, to use
as a shorthand:
ref := &lst[len(lst) - 1] # I know syntax is wrong, but you get the
idea
and then using the last element of the list by (assuming the element is
a dict):
ref["foo"] = 42
ref["bar"] = "Ni!"
etc.

I knew there was an easy way :)
Just to satisfy my curiousity: Is there a way to do something like the
reference solution I suggest above?

No. You cannot overload assignment.
Of course, for mutable objects you can use the object as the "reference" to
itself.

I have the impression that this is not an issue, to overload assignments,
which btw. *can* be overloaded, but the absence of *aliasing* (undiscriminate
handling of pointers) in Python. Am I wrong?

So there is no way in Python to make an alias for an object?
/David
what do you mean by alias ?
a = b
now both a and b refers to the same object. pi************@ gmail.com wrote: So there is no way in Python to make an alias for an object?
/David
I just want an alias. Ideally, I don't want to deal with pointers or
special reference "types" etc. After all, this is not C++ :)
I just want to be able to make a reference to any old thing in Python.
A list, an integer variable, a function etc. so that I, in complicated
cases, can make a shorthand. If "myRef" could somehow "point at"
something long an complicated like a[42]["pos"][-4], that might be
useful.
/David
But if lst[42]["pos"] happens to hold an integer value, then
a = lst[42]["pos"]
will _copy_ that integer value into 'a', right? Changing 'a' will not
change the value at lst[42]["pos"]

I'm trying to make a function which insert an object into a list and returns
an iterator to the new element in the list. But as far as I know there is no
function which returns an iterator to the last element of a list. (.end()
returns an iterator one item past the end of the list) How could I solve
this?

Is there an easy way to get an iterator (*not* a reverse-iterator) to the
last element in a list? The last() function returns the element itself, not
an iterator.
Thanks,

Forgive my newbieness - I want to refer to some variables and indirectly
alter them. Not sure if this is as easy in Python as it is in C.
Say I have three vars: oats, corn, barley
I add them to a list: myList
Then I want to past that list around and alter one of those values.
That is I want to increment the value of corn:

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:
