The result of calling divmod() is a two-element tuple. You access the 
elements by indexing:

  >>> a=divmod(10, 3)
  >>> a[0]
3
  >>> a[1]
1

You can also use tuple assignment to assign the two values to two 
variables (you can use other names than div and mod):
  >>> div, mod = divmod(10, 3)
  >>> div
3
  >>> mod
1

BTW you can't put an assignment in an if statement in python so your 
original code might be written as
div, mod = divmod(x, y)
if div...

I guess this is more C code. It doesn't have any Python equivalent - 
Python doesn't declare variables and doesn't have unsigned integers.

You might be interested in the divmod() function:
  >>> help(divmod)
Help on built-in function divmod in module __builtin__:

divmod(...)
 divmod(x, y) -> (div, mod)

 Return the tuple ((x-x%y)/y, x%y).  Invariant: div*y + mod == x.

  >>> divmod(10, 3)
(3, 1)

You will in general get a better response from this list if you tell us 
what problem you are trying to solve, rather than showing brief snippets 
of C. Even better is to attempt a solution in Python and let us see 
where you get stuck. Have you read any of the tutorials I pointed out? 
Programming Python is quite different from C and you should try to get 
the flavor of it.

Your question is meaningless to me! Please clarify.

div_t is not a Python constant or built_in.

div_t div_T; is not a Python expression.

Python integers are signed.

Does any of this refer to another lannguage?

Hi,
 
What is the usage of div_t in python?
 
I have some unsigned integer variables and want to use ;
 
div_t div_T;
div_t div_N;
div_t div_B;
.
.
..
 
Best for all,
 
Burge
