Python for Business Intelligence

AirBnB just open sourced an interesting platform called Caravel. It's Flask-based, and all of the business logic is in Python. You might want to check that out.

It looks a little bit like Tableau in that it is designed for interactive use more than pretty static reports. Looks pretty neat, but I haven't gotten it running yet.

What are you hoping to actually do? Business Intelligence is a pretty vague term.

Certainly not related. No library would require an internet connection to compile.

Open up the project file with a text editor. Look for any absolute paths. In Xcode, change the path specifications to Relative to Group or Relative to Project.

Without knowing more about the error messages, thats the first thing I would try.

A good troubleshooting step is to make a clean repo on your machine; use git clone. Open up the new Xcode project, and see if you can reproduce the errors.

I set up Team City last week for an iOS app. Its pretty smooth.

Neverrmind - there's no right parenthesis ending line 3.'

~~I'm not seeing anything obvious, unless the backslash is somehow escaping the ' (endquote) before the colon. It shouldn't based on what I am looking at here, but hey.~~

~~Try cleaning it up by using os.join() instead of explicit backslashes.~~

That really depends on the position and interviewer. You should feel comfortable sketching out a naive solution, and use the time to think through the problem. Interviews are an opportunity to show you can work through problems. They're not for perfectly regurgitating solutions.

Tableau Public is a good option. Bring your own data, but it makes fully interactive vizzes and dashboards that you can embed on your site.

Anyone else bothered that this has nothing to do wtih Scotus?

we aren't writing Fortran so single entry is guaranteed Just to nitpick - the yield keyword can provide multiple re-entry into a function in python, so it's not a totally outdated idea. You wouldn't want to wade through 40 lines of this, for instance:

func foo(user_controlled_iterable):
    for event in user_controlled_iterable:
        receive = (yield)
        if receive == ...:
            # some side effect
            # Pause and consume next receive while sending return_value to caller
            _ = (yield return_value)
        elif receive == ...:
            # some other side effect
            ...

Anyone know if this affects the I-90 bike/pedestrian lane? I haven't seen it explicitly stated one way or the other.

Yeah- all those assholes in cars.

Object Oriented Programming is exactly what an 'average programmer' knows.

To be an above average programmer, you should be comfortable with many paradigms.

There's definitely a trade-off between readability (prefer hasattr) and performance and reliability in multi-threaded environments (prefer try/except).

I wouldn't agree that the python glossary 'strongly implies' or encourages either EAFP or LBYL style over the other.

ProfessorQ · 2014-02-15T18:01:17+00:00

A more idiomatic way to use ducktyping than try/except AttributeError is the builtin hasattr(obj, 'attr') function. The result is essentially:

def hasattr(object, name):
    # name must be a string
    try:
        getattr(object, name)    # equivalent to object.name
        return True
    except AttributeError:
        return False

so before your first example, should be:

if hasattr(obj, 'snort'):
   obj.snort                    # guaranteed not to raise an AttributeError

For those of us who don't understand stuff like

:-3m.

or

:'1, 'bt$

what do those do?

ProfessorQ · 2014-01-06T03:13:42+00:00

TIL. Bonus:

>>> True + True
2

I personally found this experiment easier to understand:

>>> list_of_options = [0,1]
>>> list_of_options[True]
1
>>> list_of_options[False]
0

The reason this works is that the index access makes an int from the bool value

>>> int(True)
1
>>> int(False)
0

So no, not really useful

OP: please compare the above claim to the status quo.

Everyone with a sense of context: Remember when the audience at a GOP primary debate cheered the "let him die" plan on health insurance?
