>>> lst = [1,2,3]
>>> len(lst)
3
>>> lst.__len__()
3
in genereal all objects which implements __len__
can be passed to built-in function len
>>> len
just to give one example how this can be used
>>> class X(object):
... def __len__(self):
... print "this instance has __len_
Thanks !

Note, however, that if you goal is to create a simple C-level pointer of
machine ints you'll need to use Numpy or a similar system that
implements such a type.
Have fun,

The array module allows you to specify a single type of elements.

Is it possible to limit the size of list in python.
I want to make list of 5 elements. How can I achieve this thing in
python. And one more thing can we declare list to store elements of
same type as in c, C++ we can declare an
array which can have 5 elements of type int.
C, C++:
int intarr[5

But what if I wanna construct an array of arrays like
we do in C++ or Java:
myArray [][]
Basically, I want to do the following in Python:
myArray[0][1] = list1
myArray[1][2] = list2
myArray[2][3] = list3
here you have to be careful to create N

myArray[1][2] = list2
myArray[2][3] = list3
How to do this, gurus?
You might be able

A list does not have a fixed size (as you probably know)
But you can initialize it with 10 somethings

I cannot figure out how to specify a list of a

For example, I want to construct a list of size 10,
how do I do this?
