because Python is a portable high-level language. if you want
assembler, you shouldn't use Python.
did you read the "reset your brain" article ?

Hi all,
Congratulations, you understand both Hinduism and Python better than Ido now. :)

Hi all,Say that you copy the contents of file foo into file bar and delete
the original foo. Of course file bar still exists in this case. Notmuch of a difference; I haven't seen buffer objects yet (I am also newto Python), but the initialization for the buffer probably copieswhatever is in y somew

no. there are no C-style "variables" in Python; just objects and names
bound to objects. Python variables are names, not memory locations.

Just as an obscure sidenote, in PyPy it is ~address some of the time.
This is due to the fa
Hi all,
in the CPython implementation, it's the address where the object isstored. but that's an implementation detail.
ok so can i point a vairiable to an address location just as done in C language ?
>>> y = 'ATGCATGC'
>>> x = buffer(y)
>>> del(y)
>>> x
>>> print x
ATGCATGC

The id may be considered similar to an address in

no, it's the object identity, and all it tells you is that both names
point to the s
Hi all,
was looking at references in python...
>>> a = 10
>>> b = a
>>> id(a)
153918788
>>>id(b)
153918788
where a and b point to the same id. now is this id an address ?
can one dereference a value based on address alone in python?
is id similar to the address of a variable or a class ?
