Soni,
Answering off-list by moderator request.
Before I go on to respond to the details, let me start by saying I'm
definitely beginning to understand why you like the Rust syntax for
traits, and maybe even some feeling for the semantics, although
they're not very well documented anywhere I found

This module should contain operations that can be performed on binary numbers.
In the below examples a and b are binary numbers.
binary.add(a,b)
binary.sub(a,b)
binary.mul(a,b)
binary.div(a,b)
binary.ones_complement(a)//returns 1's complement of a.
binary.twos_complement(a)//returns 2's co

Please can you clarify what this means, in Python terms? Are you proposing a
_new_ Python type that represents a "binary number", or is `binary.add` (for
example) intended to work with existing Python typ
And what do you call "decimal numbers"? Decimal representation of
numbers like returned by str(123456)?

I'm proposing a module that has functions intended to work with existing python
types.
Digital electronics is completely based on "binary number system".As python is
used in almost all fields,by adding a seperate module for binary containing
operations like ones complement and twos complement

Okay, great. *Which* Python types, specifically? `int`? `bytes`?
To help us understand, please can you show example inputs to and output from
your proposed `binar

But these aren't standard Python types - well, technically, 110011
is 1,100,111,111 - 1 billion, 100 million 111 thousand one hundred and

I see. So you want `binary.ones_complement` to accept a nonnegative Python
`int` whose decimal expansion consists entirely of ones and zeros, interpret
that decimal expansion as though it's a b
What is 110011 here? A number written in decimal where you want to
interpret digits as binary digits?
Why don't you use 0b110011 to have a litteral written in binary
representation?

what about

or should we use something like "bitstring".

That would be printed as `4`. Is that what you want?
Supposing we accept that `binary.twos_complement(0b1100) == 0b0100`. What would
`binary.twos_complem
wea are using 0b1101100002.
hence it will give you a syntax error.

Assuming you mean that a "binary number" is int then python
can do what you want I think.
binary.twos_complement(0b0011)==1101
binary.twos_complement(0b0011)==1101

How would you make that possible, when `0b0011` and `0b0011` are the exact
same integer?

Easy: you
But there is a problem with (0b1101).
5==0b101
-5==-0b101
but we want output -5==1011.
so this is not possible by using integers with base designator "0b".

I think you have two problems here.
The first is that you’re confusing integer values with integer literal syntax.
It’s not just that `0b10

Hm, but doesn't the OP's example require *synchronously* reading and

Correct. But in the OP's example, they wanted to use their own
