lol that is frustrating. i just made duplicate variable this time around

all_data2 = all_data

then when i screwed up the all_data variable it automatically screwed up all_data2 in an identical manner. didnt see that coming

Python variables are references to data structures so setting b=a below just creates a new label for "a" rather than copying a:

Code:

a = [1, 2, 3]
b = a
b.append(4)
print b # outputs 1, 2, 3, 4
print a # outputs 1, 2, 3, 4
print a is b # prints True

if you want to get a copy of a list you can do:

Code:

a = [1, 2, 3]
b = [x for x in a]
b.append(4)
print b # outputs 1, 2, 3, 4
print a # # outputs 1, 2, 3
print a is b # outputs False

Seems like it could be a neat toy to play around with but comes at a hefty price, I can probabaly get it for free if I make up a good enough excuse :P

I've used it a bit and it's pretty sweet for doing physics and stuff. Take a look at Sage which is an open source alternative based on Python.

I love it too, but when the Apple store a half hour away said they had them in stock when they actually didn't it made me a very sad Panda.

I just ordered mine now. It's at 3-4 weeks for delivery now. When I first checked it was 5-7 days. Why did I wait???

That's like asking for predictions of the future of the war between the USSR, Albania, and the USA.

dont know why this isnt standard, it tilts the shiit out of me. i was taught this way in school so whenever i saw the comma missing i would curse the editors for allowing such injustices to seep through. then one day i googled wtf was going on and saw that some people actually dont use it

Does anyone here use Sandcastle for c#? http://sandcastle.codeplex.com. I'm starting to like that I can hover over a function call and have a popup window show me a brief description I wrote about the function so now im looking into it a bit more. Also, do any C++ compilers support a similar feature? And while I'm on the topic... is it possible to write code to make your own "IntelliSense" type of thing? Or at least customize it in detail by writing code to adjust the 'stock' IntelliSense? =P

I favor the Oxford comma and that's the best defense of it I've ever seen.

Found this pretty interesting. The guy has been playing the same Civ II game for 10 years. The outcome strikes me as a pretty likely real life scenario:

ASP.NET gurus:

How much should hosting cost for an ecommerce site that does, say, 100K hits/mo and is built on DNN?

What hosts do you recommend (US based)?

What factors would make it cost more or less? And what if the number of hits was 1M hits/mo?

It's possible that I missed something, but when I was trying to develop for Mac on a windows machine, I tried a ton of things that didn't work for a while, then gave up and used a Mac.

b = a[:] is significantly faster and a bit clearner IMO:

Quote:

In [6]: t = timeit.Timer(stmt = 'b = a[:]', setup= 'a = range(1000000)')

In [7]: t.timeit(100)/100
Out[7]: 0.04913121276955991

In [8]: t = timeit.Timer(stmt = 'b = [x for x in a]', setup= 'a = range(1000000)')

In [9]: t.timeit(100)/100
Out[9]: 0.21962228900826575

It does indeed work:

Quote:

In [10]: a = range(4)

In [11]: a
Out[11]: [0, 1, 2, 3]

In [12]: b = a[:]

In [13]: b
Out[13]: [0, 1, 2, 3]

In [14]: b.append(4)

In [15]: a
Out[15]: [0, 1, 2, 3]

In [16]: b
Out[16]: [0, 1, 2, 3, 4]

You can also install a Mac VM.
