I don't know how many times I've referred to, or paraphrased,
that article. Shouldn't it be incorporated into the standard
tutorial? I think it's very he

careful: it's not the *reference* that's mutable, it's the object.
the *only* difference between mutable and immutable objects is that

Thanks for the reply, Grant.
I am not doing things like that - I am just trying to clear up in my
mind the Python concepts.
I understand it now.

There's no such thing as a "simple variable". There are
mutable objects and immutable
Thanks for the reply, both to Laszlo and Steve.
Okay, I understand what you're saying.
But what if I need to make a "pointer" to a simple variable.
For instance, in C:
int i=1
int *j=&i
*j = 2
print i
and you get 2 printed.
In Python,
i=1
j=i
j=2
print i
and you get

Hi list,
Just to make sure I understand this.
Since there is no "pointer" type in Python, I like to know how I do
that.
For instance, if I do:
...some_huge_list is a huge list...
some_huge_list[0]=1
aref = some_huge_list
aref[0]=0
print some_huge_list[0]
we know that the answere
