Sure. But the interesting part is how to design the API. I’ve seen a number
of interesting ideas in this thread.

It seems to me that this could simply be a package on pypi rather than being
added to the Python standard library.

Just float, or any type convertible to int?
The module should also support bit masking (left or right justified) with
AND / OR / XOR / NotAND / NotOR / NotXOR operations.
ieg following the same structure:
binary.AND(a,b)
binary.OR(a,b)
binary.XOR(a,b)
binary.NOTAND(a,b)
binary.NOTOR(a,b)
binary.NOTXOR(a,b)

I think you have two problems here.
The first is that you’re confusing integer values with integer literal syntax.

There is no such thing as an 'integers with base designator
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".
so we have to use new Python type that represents a "binary number",which
accepts
number of bits,sign of number.

Easy:
a and b should be integer with base designator "b" (0b110011) .OR there should
be a_new_ Python type that represents a "binary number",which accepts number of
bits,sign of number.

Assuming you mean that a "binary number" is int then python
can do what you want I think.
wea are using 0b1101100002.
hence it will give you a syntax error.

That would be printed as `4`. Is that what you want?
Supposing we accept that `binary.twos_complement(0b1100) == 0b0100`. What would

What would you expect ones_complement(1100) to return? (I'm guessing you'd
expect a Python int with value 11.)

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?

I see. So you want `binary.ones_complement` to accept a nonnegative Python

Okay, great. *Which* Python types, specifically? `int`? `bytes`?
To help us understand, please can you show example inputs to and output from
your proposed
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
And what do you call "decimal numbers"? Decimal representation of
numbers like returned by str(123456)?

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
