The only difference is that I need to add a space after the commas. Once it does that NoteCaddy is able to read the HH and take notes on it.

I'm wondering what language I would need to do something like this and if anyone can lead me to someone who can write something like this. Also how much would it cost me to hire someone to write this for me?

something like that?

Lol. I doubt that the guy who posted the question will even understand WTF this answer is supposed to mean from the way he asked the question.

To answer the question, I'd guess you pay about 10$ for this if you have to. What well named posted is simply using the Unix/Linux+sed shell to get the files on the format you want. You can get this done with any language with decent regular expression support like Python,Ruby,Perl and whatnot.

Basically post "Easy file conversion/RegExp, script needed for YOUROSHERE: 10$ reward" on some programmer for hire board. This should include the script and clear instructions on how to use it on your OS (I'm assuming Windows)

You can probably get it for 5$ or so but I'm assuming 5/10 is not a huge difference for you so just go with a sum that'll get you a good result guaranteed.

Wow, this seems totally broken to me.

Code:

class A:
    def __init__(self, a): 
        self.a = a 

def foo(o=A(3)):
    print o.a 
    o.a = 4 
    print o.a 

foo()
foo()

Code:

Edit: Guess I should have read the stackoverflow link first.

I need to think about what the guy is saying in the stackoverflow link but it still seems like a poor design decision. Just because you can justify something with a high level explanation doesn't mean that its the right thing to do.

The decision strikes me as elegant from the perspective of the language implementer, but really hairy from the perspective of the language user.

What's the alternative though? Only allow pure constants as default arguments? Evaluating at function invocation is also going to surprise people under a different set of circumstances.

The design flaw to me is that python encourages use of mutable data structures.

Which set of circumstances? I can't think of any off the top of my head.

Very well said Neil.

Just seems to me that invoking a function with a default argument of [1,2,3] passed with no arguments, should behave the same as if I invoke with an argument of [1,2,3].

To me it's not about problems, or when things should be instantiated, or magical scope issues. It's about a default argument working the same as an explicitly passed argument.

Not the same language, but I don't give a parameter a name in the definition if I'm not going to use it. Avoids an unreferenced parameter warning. Something can belong in the interface but not be used in the implementation.

@TheMetetrown
Since you seem to be serious about getting into this, pick up a copy of "The Pragmatic Programmer" and read it on the side.
[in before a billion similar books are recommended but I think this is the most solid read on the side if you want to get into programming kind of book]

The pragmatic programmer was one of the few computer related books I read. I actually have every tip written on paper on my desk on a piece of paper. I glance over it from time to time.

You're missing out on a lot of great books then

Lol-books is way overused for IT related topics imo

(also if your time is worth anything they are +EV because you don't have to search for stuff and they are generally good collections of certain domains)

It's not a terrible thing. I can do streaming and lazy evaluation:

Code:

def streamOfBaseTwos(listOfBaseTwos = [1]):
    listOfBaseTwos +=[listOfBaseTwos[-1] + listOfBaseTwos[-1]]
    return listOfBaseTwos
 
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())
print(streamOfBaseTwos())

for i in range(10):
    n = streamOfBaseTwos()
    print('2^' + str(i) + '=' + str(n[-1]))

Code:

>>> [1, 2]
[1, 2, 4]
[1, 2, 4, 8]
[1, 2, 4, 8, 16]
[1, 2, 4, 8, 16, 32]
[1, 2, 4, 8, 16, 32, 64]

Guido is not a fan of Lisp, not a fun of functional programming, thus I suspect he's not a fan of the list data type, which is why it sometimes feels like a huge middle finger when you get too fancy with lists in Python.

TheMetetrown: JJ is correct, that code I posted is a terrible thing.

i was in a meeting today at work about our mail systems. one of the reports we looked at showed delivery failures. mostly it was stuff like hotmai.com and verion.com -- places where people typo'd while trying to enter an address. my boss was interested in the top entry:

boss: "what's homail.com?"
me: "it's where your mom checks her email."

Speaking of Python wat, here is something I just discovered today:

Code:

# assume L is a list both times

def f1(L):
    L += [1]

def f2(L):
    L = L + [1]

They don't do the same thing. Even Guido thinks this is horrible.

Re: the mutable defaults thing, I've been using Python for awhile and I've actually been bitten by that bug zero times, and written code that depended on that behavior, but I'm inclined to agree with Neil in principle and regard it as "probably a necessary evil." I don't really know how you would fix it without copy.deepcopying the defaults dict every time the function is called, especially when you consider the possibility of nested mutable structures.

Re: why the other way could ever be a gotcha, here's an example stolen from the SO post:

Code:

bread = (1,2,3)

def toast(food = bread):
    # do things

# bunch of other code

bread = (8, 6, 7, 5, 3, 0, 9)

# a lot of other code

toast()

daveT: I don't understand why it follows that hates FP = hates python lists. Wouldn't FP types like tuples better anyway since they have essentially every property of lists except side effects?
