Esoterically speaking, you should better distinguish between historic and 
individual time.

Python's foo is like Java's foo speaks of the individual's exoteric order 
of 
experience with Python and Java, that may reverse esoteric historical 
chronology (and in fact, does so).

I think in Matlab, as in Fortran 90, i:j refers to the elements from i
up to and including j, unlike Python, where j is excluded. Another
language with slicing is S, implemented in S-Plus and R. It follows the
same convention as Fortran.

The languages treat negative subscripts of lists and arrays
differently. In Fortran, since lower bounds of arrays can be negative,
a negative subscript has no special meaning. In S, where arrays start
with element 1, a negative subscript means that the absolute value of
the subscript is excluded, so that if array x has three elements, x[-2]
refers to (x[1],x[3]). In Python, negative indices wraparound.

Wildemar Are there any concepts that python has not borrowed, concepts
Wildemar that were not even inspired by other languages?

I'd say Guido's willingness to borrow heavily from the best ideas present in
other languages ranks right up there as one of its key concepts.

1. One of the strenght of Python is that it does not try to be
particularly original, most of
the times it just borrows the good features from other languages
without borrowing the
warts.

2. If you ask in a Lisp newsgroup, they will tell you that they
invented everything that it is
cool now (in any language) over 40  years ago. They are also mostly
right ;)

2006-04-21 Thread dadapapa
It's true that most features of python are intentionally borrowed from
other languages. If I can think of anything that I believe to be
specific to python, I would say it is the combination of high level
datatypes together with an extremely simple syntax. Actually, this
combination often results in idioms that --- although adapted from
other languages --- are seldom as clear as in python. Examples for this
are one-liners like

 x,y = y,x
 a,b,c = f(x)
 for key in my_dict : do_some_thing_with(my_dict[key])

It might be that Guido adapted such notations from ABC, a language I am
not familiar with, but as far as I know, the syntactic sugar for high
level datatypes is one thing that
distinguishes python from other languages.

I find slice notation consistent and elegant - did it come form another

In the Tutorial, the BFDL says:

Strings can be subscripted (indexed); like in C, the first character of
a string has subscript (index) 0. There is no separate character type;
a character is simply a string of size one. Like in Icon, substrings
can be specified with the slice notation: two indices separated by a
colon.

Since Python was released well before Java, saying that a feature in
Python is like a feature in Java normally doesn't mean that Python
imitated Java there -- it's either separate reinvention, or both of them
imitating another language.

like the hashtable in java

People don't give a reference to a language feature only because it
added/invented it but also because it is a popular one that many are
familiar with.

Java did not invent HashTables. They existed long before and were
available to most languages before Java. Neither is it even a Java
programming language feature (it's a class in it's standard library).

Actually, I can't think off the top of my head, any feature in the Java
language (and I am making no assertions about the implementation of
specific instances) that was truly innovative. But that's OK.
Incremental is good.
