Hello Sir/Mam, Could you please help me with my current research ? Am implementing the concept in python language. My doubts are : 1) Is it possible to Retrieve the address of a variable in python ? 2) Is it possible to Delete the Address of the Variable and create a new dynamic address inside the compiler/interpreter itself ? 3) Is it easy to find the Binary equivalence of a given Alphanumeric String ? 4) Is it possible to count the number of 1's in the Binary equivalence ? Could you PLEASE provide me with the codes (codes only for the asked queries) ? Your reply counts a lot for me and my research ! I love to explore more in python. Awaiting for your Response (Please reply ASAP). Best, Bharath (+91 9025338332)

No. One of the fundamental concepts of Python is that it completely
hides the physical memory. Sure, at some point, when you write
x = 42
it allocates some piece of memory and puts the integer 42 into it, but
all those details are hidden from you (and are implementation specific).

I think what you're talking about is the ord() function. Given a single
character (i.e. a string of length 1), it returns the unicode value for
that character. Thus:
>>> ord('X')
88
You could iterate over the characters in a string to find that for each
one:
>>> [ord(c) for c in "My string"]
[77, 121, 32, 115, 116, 114, 105, 110, 103]
> 4) Is it possible to count the number of 1's in the Binary equivalence ?
This is starting to sound like a homework problem, or possibly an
interview question :-)

No. Variables in Python are not at fixed addresses, like in Pascal or C,
they are names in a namespace.
You can read this post for some more information about the difference
between C variables and Python variables, and calling conventions across
different languages:
https://mail.python.org/pipermail/tutor/2010-December/080505.html
It's a long post, but to summarise the part about variables:
In languages like Pascal or C, the compiler keeps a table mapping
variable names to fixed memory addresses, like this:
Variable Address
======== =======
x 10234
y 10238
z 10242
The command "x = 42" stores the value 42 into memory address 10234. If
you ask the compiler for the address of x, it can say 10234. That's how
variables work in languages like Pascal, C, Fortran, and similar.
With the Pascal or C style variable, the variable address exists even
before you give it a value.
But languages like Python don't work that way. There is no table of
variable:address available to the compiler, and variables don't have an
address. Python's variables are *name bindings*, not fixed memory
addresses. The Python runtime keeps a global dictionary which maps names
to their values:
{'x': <integer object 42>,
'y': <string object 'hello world'>,
'z': <list object [1,2,3]>,
}
The general name for this is "namespace". In Python you can access the
global namespace with the globals() function, and a read-only copy of the
local namespace with the locals() function.
Entries in the namespace cannot be blank. So names don't exist before
they are bound to a value.

> Is it possible to Delete the Address of the Variable and create a new
> dynamic address inside the compiler/interpreter itself ?
I don't understand this question.
Since variables don't have addresses, you can't delete what doesn't exist.
> 3) Is it easy
> to find the Binary equivalence of a given Alphanumeric String ?
Which binary equivalence are you referring to? Again, I don't understand
your question. I can do this:
py> astring = "1234"
py> int(astring).to_bytes(4, 'big')
b'\x00\x00\x04\xd2'
py> int(astring).to_bytes(4, 'little')
b'\xd2\x04\x00\x00'
Or I can do this:
py> astring = "Alpha1234 δθЖ∞"
py> astring.encode('utf-8')
b'Alpha1234 \xce\xb4\xce\xb8\xd0\x96\xe2\x88\x9e'
Or I can do this:
py> import binascii
py> binascii.hexlify(b'Hello World!')
b'48656c6c6f20576f726c6421'
And many other string -> binary equivalences. Which ones did you have in
mind?
> 4) Is it possible to count the number of 1's in the Binary equivalence
> ?
Of course. First decide which binary equivalence you want, then decide
what you mean by "count the number of 1s" (do you mean the byte with
value 1, or the ASCII code for 1, or the bit 1?), then count them.

If you explain your question in more detail, we can give more detailed
answers.

FWIW, that's only true for some sorts of variables. Other variables
have an address that is relative to a stack or frame pointer.

I love to explore more in python. 1) id will give you addresses. Except that - not portable ie not guaranteed to be a m/c address - its of an object not a variable - if you are thinking C, its mostly useless 2) del will delete objects -- like free in C Except that like above, thinking in C will cause more problems than it solves 3,4 I cant make out what you mean

Whether the bound object is also deleted depends on whether it is still referenced, and the timing by which the bound object may be deleted varies between implementations.

It merely removes references to objects. Only if the object has no more references is the object deleted.

I'm not an expert on Indian English, but I understand that in that dialect it is grammatically correct to say "the codes", just as in UK and US English it is grammatically correct to say "the programs". In other words, in UK/US English, "code" in the sense of programming code is an uncountable noun, like "rice" or "air", while in Indian English it is a countable noun like cats or programs. We have to say "give me two samples of code", or perhaps "two code samples", while an Indian speaker might say "give me two codes". As this is an international forum, it behoves us all to make allowances for slight difference in dialect. Aside: I love the fact that pea, as in green peas or black-eyed peas, is a back-formation from an uncountable noun. Originally English had the word "pease", as in "pease porridge hot" from the nursery rhyme. Like wheat, rice, barley and others, You would have to say something like "give me a grain of pease" if you only wanted one. Eventually, people began to assume that "pease", or "peas", was the plural and therefore "pea" must be the singular. I look forward to the day that "rice" is the plural of "ri" :-) -- Steven

I wouldn't necessarily even consider it an Indian thing, as I've known Americans to use the same phrase.

But it does seem a more likely candidate for a hypothetical back formation than "ri", which perhaps was your point.

In my experience it seems to be a scientific community vs. computer science community thing. I often hear Fortran people talk about "a code" where we would say "a library" or "a piece of code". -- Greg

To the best of my knowledge, the word program didn't start to creep in until later. I'm guessing, but I'd assume it started to arrive with the first computer science graduates. -Bill
