pythondev | help | I have here a very small unit test program which is supposed to test
that an object throws an AttributeError exception when a nonexistent
attribute lookup is attempted.

It works fine, but I had to put the attribute access in a function.
I'd rather not define that function and use the assertRaises as follows:
self.assertRaises(AttributeError, lambda item: item.donation)
However, this gives me a "TypeError: <lambda>() takes exactly 1 argument (0 given)"
Is this somehow possible without helper function?

pythondev | help | I know you can use a `with` block in some other test packages, but to be honest this seems like a weird thing to be testing for | 2017-07-21T10:04:21.814254 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:04:21.814254 | 1,500,631,461.814254 | 86,680 |
pythondev | help | You could probably use `self.assertIn("donation", item.__dict__)` or some similar abomination if you really want a one-liner | 2017-07-21T10:06:22.885754 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:06:22.885754 | 1,500,631,582.885754 | 86,681 |
pythondev | help | <@Gabriele> Yeah it sounds weird, but actually the object under test is some kind of container giving both attribute and keyed lookup access to a set of properties, and I need to test whether the right exceptions are thrown during lookup of a nonexistent property. | 2017-07-21T10:14:24.161608 | Ruben | pythondev_help_Ruben_2017-07-21T10:14:24.161608 | 1,500,632,064.161608 | 86,682 |
pythondev | help | Sounds like a bad idea to me. But if I had to write tests for it, I'd just use the __dict__ check directly. Or `hasattr`. | 2017-07-21T10:16:49.245549 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:16:49.245549 | 1,500,632,209.245549 | 86,683 |
pythondev | help | <@Gabriele> Bad idea? You have a better idea? Thanks for the `hasattr` tip! This is what it's all about, the `Bunch` object: <https://github.com/motoom/bunch> | 2017-07-21T10:20:30.373050 | Ruben | pythondev_help_Ruben_2017-07-21T10:20:30.373050 | 1,500,632,430.37305 | 86,684 |
pythondev | help | I think that is unnecessarily blurring the lines between a container and a type. If you don't know what attributes a type has, then you don't really know what interface it provides, which makes it a very awkward object to work with | 2017-07-21T10:21:21.402618 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:21:21.402618 | 1,500,632,481.402618 | 86,685 |
pythondev | help | <@Gabriele> I use it declutter my source code. Basically it is a `dict` like object where you don't have to type `["` and `"]` all the time. So I can write:``` | 2017-07-21T10:23:03.461371 | Ruben | pythondev_help_Ruben_2017-07-21T10:23:03.461371 | 1,500,632,583.461371 | 86,686 |

pythondev | help | Psycopg2 has a `NamedTupleCursor`, which provides the same syntax. | 2017-07-21T10:25:11.534439 | Ruben | pythondev_help_Ruben_2017-07-21T10:25:11.534439 | 1,500,632,711.534439 | 86,688 |
pythondev | help | In that case, at least the schema is documented elsewhere. But I don't like it. | 2017-07-21T10:26:04.565260 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:26:04.565260 | 1,500,632,764.56526 | 86,689 |

pythondev | help | In the general case, yes. It's not exactly a great hardship. In a database context, it might be nice to have a type that directly reflects the DB schema - which is what we have ORM for | 2017-07-21T10:28:32.653471 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:28:32.653471 | 1,500,632,912.653471 | 86,693 |
pythondev | help | btw, the `NamedTupleCursor` gets its attribute names from the fields behind the *SELECT*. I.e. `select name, salary from Employees` would result in *.name* and *.salary* attributes on the tuples in the resultset. | 2017-07-21T10:29:33.689487 | Ruben | pythondev_help_Ruben_2017-07-21T10:29:33.689487 | 1,500,632,973.689487 | 86,694 |
pythondev | help | I just really dislike things that attempt to cut down on a bit of typing by ruining the interface. Several parsers do it, like BeautifulSoup. lxml.objectify is even worse | 2017-07-21T10:30:25.720812 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:30:25.720812 | 1,500,633,025.720812 | 86,695 |
pythondev | help | I wouldn't call it ruining. It makes the code more readable to me. I prefer dot notation over index lookup with a string. | 2017-07-21T10:31:34.762088 | Ruben | pythondev_help_Ruben_2017-07-21T10:31:34.762088 | 1,500,633,094.762088 | 86,696 |
pythondev | help | The dot notation and the index lookup carry different information. `x.y` implies that `y` _must_ exist. `x["y"]` implies that a value for "y" might exist, if someone added it earlier. | 2017-07-21T10:33:07.816673 | Gabriele | pythondev_help_Gabriele_2017-07-21T10:33:07.816673 | 1,500,633,187.816673 | 86,697 |

pythondev | help | Ah, we have a different view on that too. When I see `x["y"]` in code, I assume the programmer knows that an *y* value is present, or should be present (punishable by KeyError). When I see `x.get(y)`, then I know the programmer is trying to communicate to me that *y* perhaps does not exist in *x*. | 2017-07-21T10:34:42.873174 | Ruben | pythondev_help_Ruben_2017-07-21T10:34:42.873174 | 1,500,633,282.873174 | 86,699 |
