Compare a few different languages. Python: If you don't declare, it's global if you don't rebind it, but local if you do. You may declare variables as global or nonlocal. PHP: If you don't declare, it's local, but functions are in a separate scope. C: If you don't declare, it's looked for in some broader scope. If it's not declared in any scope, error. All three approaches make reasonable sense. The PHP one is perfectly consistent, but would be hopelessly impractical if all your function names had to be marked off as globals. (Plus PHP has superglobals, with their own Marvellous mess.) Python's system "just works" most of the time, but can introduce yet another trap for the unsuspecting newbie who doesn't understand the difference between rebinding and mutating; I've not looked into multiple levels of closures but I suspect there'll be odd limitations there, as there's only one "nonlocal" keyword. The C style has administrative overhead (requiring explicit declarations for all variables), but allows full flexibility (variables having narrower scope than entire functions, infinite nesting of scopes, etc). Incidentally, variable declarations don't have to be connected with static typing. JavaScript/ECMAScript simply has 'var x;' to declare that x exists in this function. But it's hardly a language that I'd hold up as a shining example; a var declaration anywhere in a function makes that variable name local to that entire function. There's actually no block scoping at all. And then there's the whole confusion of the global object, 'this', and 'with' statements... You knew I was going to cite it sooner or later :) Pike has true block scoping, though unlike C++, Pike does not guarantee that destructors will be called immediately at the close brace (but zero-reference objects will be cleaned up, including destructor calls, at the next function return - even if not the current function). Variables can be mostly-statically-typed, or can be declared as 'mixed' and be rebound freely (like in JS and Python). So scoped variable declarations and static typing are quite orthogonal.

Variable declarations serve two purposes. One is to declare the type (which obviously doesn't apply to Python). The other is to declare the beginning of a scope. On occasion, I will make typos in variable names which a scope-introduction declaration would have prevented. If the cost of having to declare every variable would be justified by the rare bug it would prevent, is another question. Pet peeve of the day...

We currently have two calendars in place: * Python Events Calendar - meant for conferences and larger gatherings focusing on Python or a related technology (in whole or in part) * Python User Group Calendar - meant for user group events and other smaller local events The calendars are displayed on http://pycon.org/ and in a smaller version in the sidebar of the http://python.org/ website (at the moment only the main events calendar is shown there). ADDING EVENTS If you want to have entries added to those calendars, please write to [email protected] and include the following information: * Name of the event * Type of the event (conference, bar camp, user group, etc) * Focus on Python * URL * Location and country * Date and time (if relevant) For recurring events, please also include a description of the recurrence in a way that's compatible and supported by Google calendars.

You don't need to export this function because it's listed in the

If it 'disappears', it still exists and can be re-activated whenever you want (as long as you keep an active reference to it). Once you destroy the widget, there is no recovering it.

On my wishlist for Python is a big, fat SyntaxError for any variable that could be interpreted as either local or nonlocal and is not explicitly declared as either. It would eliminate this sort of confusion entirely and make code that shadows nonlocal variables much more readable. Ideally, the same thing would also be done for locals that shadow globals, but I don't see how that could possibly be enforced at compile time. -- http://mail.python.org/mailman/listinfo/python-list

Hello Joe, Can you tell us more about the Solaris box? I'm especially interested in the Solaris version, architecture (sparc or X86_64) and your C compiler. We have Python up and running on a Solaris 10 box (sparc) and a Solaris 11 box (X86_64) with Sun CC and GCC 4.6. You could try to recompile Python with the Sun CC: $ make distclean $ ./configure --without-gcc --config-cache $ make Christian -- http://mail.python.org/mailman/listinfo/python-list
Style help for a Smalltalk-hack
I'm writing some code that does a structured read from formatted binary file.
The code I came up with looks like:
# get the first four bytes, the first gap field
chunk = byteStream.read(4)
while chunk:
# interpret the gap bytes
gap, = struct.unpack('>I', chunk)
# suck off the valveCount
valveCount, = struct.unpack('>I', byteStream.read(4))
# collect the next valveCount signatures
signatures = [struct.unpack('>I', byteStream.read(4))[0] for _ in
range(valveCount)]
self.script.append(ScriptSpan(gap=gap, valveSet=signatures))
# now get the next 4 bytes for the gap of the next iteration, it'll be
empty if we're at end
chunk = byteStream.read(4)
I can't help but thinking that there's some better way (i.e. more pythonic) to
do this that doesn't involve having to use another module (Construct) or
exploring generators or something like that. What bugs me about it is that
there is two different styles for reading/decoding values from the byte stream.
valveCount and signatures are both paired invocations of unpack() and read().
But to detect the end of the stream (file), I have to split the read() and
unpack() of the gap value across 3 different lines of the code, and they don't
even sit adjacent to each other.
I'm wandering up the Python curve with a passel of Smalltalk experience under
my belt, so I expect I'm struggling with trying to map something like this
across to python
[byteStream atEnd] whileFalse: [
gap := (byteStream next: 4) asInteger.
valveCount := (byteStream next: 4) asInteger.
signatures := (1 to: valveCount) collect: [:_ | (byteStream next: 4)
asInteger].
self script add: (ScriptSpan gap: gap valveSet: signatures).
]
The part that doesn't seem to be there in the standard python library is the
idea of an atEnd message for streams, it's inferred as a byproduct of a read().
Please be gentle/kind. I'm still learning. :) TIA

Another way you could do it is:
while True:
chunk = byteStream.read(4)
if not chunk:
break
...
And you could fetch multiple signatures in one read:
signatures = list(struct.unpack('>{}I'.format(valveCount),
byteStream.read(4 * valueCount)))
By the way, in Python the recommended style for variable names (well,
what you'd call a 'variable' in other languages :-)) is lowercase with
underscores, e.g. "byte_stream".

The latest Python version is systematically slower than the previous ones as soon as one uses non "ascii strings".
