Javascript is weakly typed but you don't have buffer overflow problems there. Hmm... this is going to get tricky, since everyone seems to have different opinions on what these terms mean. I'm very confused about JavaScript. Why do you say it's weakly typed? I did a quick web search on this, and most people seem to agree with you, based on the fact that in JavaScript: hello + 10 hello10 10 + hello 10hello So everything can be, uh, promoted to a String. But can I, say, take an Object and treat it as a number? Or an Array as a String? Or is JavaScript weak in certain directions and strong in others? Maybe you should let on what you mean by strong/weak typing. What I meant by saying that weak typing in C/C++ causes buffer overruns is that everything is just a memory location, since you can arbitrarily switch between pointers and types, which means that you can't have sanity checks for array accesses (which are your buffer overruns) without changing the language itself. I would assume that people are arguing for strong typing for efficiency. A language with run time dynamic dispatch, like say Python, will always be slower than something which is statically typed. Again why would strong typing get you efficiency? Am I comparing apples and potatoes, if I am please do let me know. I say that run time dynamic dispatch is slow because you always need to look things up, specially in python since you can arbitrarily change anything at runtime, on the other hand, if you have a strongly typed language (thanks for catching that) then you know at compile time what you want your code to do, hence you don't have to find that out at runtime, time saved doing that makes your language faster all other things being equal. I could be horribly wrong, I don't know enough about programming languages to be sure. So please do let me know if you think so. How about this, lets make it less controversial and bring the talk back to safer ground: the best Python code will always be slower than high quality C++ code no matter how good the Python optimizers get. Speed might not be always important and yada-yada-yada, that's irrelevant to the last statement. I write more Python than C++, so yeah, I've heard of most of those reasons.

[BangPypers] Tip: Creating new classes on the fly
I came across this in a blog post just now.
See http://docs.python.org/library/functions.html#type
class Foo(object): pass
...
Bar = type('Bar', (object,), dict())
f = Foo(); b = Bar()
type(f), type(b)
(class '__main__.Foo', class '__main__.Bar')
Also see
http://docs.python.org/library/collections.html#namedtuple-factory-function-for-tuples-with-named-fields
from collections import namedtuple
Baz = namedtuple('Baz', '')
Anyone switched to Python 2.7 yet?

In CDAT vcs module supports only the 'float data' type to represent the latitude logitude in map. so I need float value in 2 precision without changing the value. Not in string. Not in Decimal. Well, if you can't use Decimal, you won't be able to use Python, because a float won't work for you: 80.23 80.234 Any reason why you can't use Decimal, or a string, or an integer? -- http://roshan.mathews.in/ ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

Re: [BangPypers] refactoring

Refactoring might have devolved into that now, but I don't think that's what Fowler was pushing. Refactoring assumes that the implementation of the code is not closely tied with its interfaces. In other words, it assumes some amount of separation of concerns which will allow to modify the inner guts without changing the external behavior of the code. To be pedantic, refactoring doesn't assume that, that's how it is defined. If you're changing the external behaviour then it isn't refactoring that you're doing. It's nice that Fowler named the process, and showed some of the different refactorings possible, but it'd be nice to be careful of what we use that word to describe. -- http://about.me/rosh ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
