sometimes I hate python....

Ive just chased down a bug where a simple string saved in a simple dict sometimes came out as a f*cking tuple(!) when I needed it!

turned out that at some point this dict got updated with values from some other dict. And at some other point, I decided it was a great idea to rewrite that update code into individual setter's instead ... and of course forgot to remove one the trailing comma's, thus creating a perfectly legal tuple .... *sigh*

No errors, no warnings - just plain corrupt data....

First of all, I hate crammers so much. These people kill the industry without even understanding it. They turned interviews into exams, missed the point of hiring, and saw no distinction between knowledge and information all the time. They don't understand that if you can google an answer in five seconds, it's not knowledge. It's information.

They don't understand that questions like 'what will Python do if you delete an item from a dict while iterating over it' are complete nonsense. They don't understand that it's not 'dig deep'; it's just a bad practice that leads to errors, thus must be avoided. The fact of remembering 'RuntimeError: dictionary changed size during iteration' means that you haven't been avoiding it enough.

One more example. Which signature is correct?
- ApplicationListener<ContextRefreshedEvent>
- ApplicationListener<ContextRefreshEvent>
- ApplicationListener<RefreshedEvent>
- ApplicationListener<RefreshEvent>

Second. What's the point of forcing you to write compilable code in google docs? Do they really expect that one could possibly remember 'import org.springframework.beans.factory.annotation.Autowired;'? Seriously?

Third. Why do they expect me to know Spark, Java, J2EE, Spring Boot, Python, Kafka, Postgres, React/Redux, TypeScript, and work for miserable 70K EUR?

What's wrong with the European IT job market? Are they fucking nuts?

Buffer usage for simple file operation in python.

What the code "should" do, was using I think open or write a stream with a specific buffer size.

Buffer size should be specific, as it was a stream of a multiple gigabyte file over a direct interlink network connection.

Which should have speed things up tremendously, due to fewer syscalls and the machine having beefy resources for a large buffer.

So far the theory.

In practical, the devs made one very very very very very very very very stupid error.

They used dicts for configurations... With extremely bad naming.

configuration = {}
buffer_size = configuration.get("buffering", int(DEFAULT_BUFFERING))

You might immediately guess what has happened here.

DEFAULT_BUFFERING was set to true, evaluating to 1.

Yeah. Writing in 1 byte size chunks results in enormous speed deficiency, as the system is basically bombing itself with syscalls per nanoseconds.

Kinda obvious when you look at it in the raw pure form.

But I guess you can imagine how configuration actually looked....

Wild. Pretty wild. It was the main dict, hard coded, I think 200 entries plus and of course it looked like my toilet after having an spicy food evening and eating too much....

What's even worse is that none made the connection to the buffer size.

This simple and trivial thing entertained us for 2-3 weeks because *drumrolls please* none of the devs tested with large files.

So as usual there was the deployment and then "the sudden miraculous it works totally slow, must be admin / it fault" game.

At some time it landed then on my desk as pretty much everyone who had to deal with it was confused and angry, for understandable reasons (blame game).

It took me and the admin / devs then a few days to track it down, as we really started at the entirely wrong end of the problem, the network...

So much joy for such a stupid thing.

Python is a fucking joke. "Readability" disguised as 150+ magic methods and values. Virtual environments to hide shitty dependency management. Strings that may or may not act as comments. No correlation between package and module names - install Pillow; import PIL. **kwargs instead of options=dict(), because why separate function arguments from arbitrary extra data? And finally, the only way to have tkinter on Windows is to install IDLE, so that some fucktard can stick their shitty app right up yours ...

Attracted by Python's powerful built-in libs, I learned it by myself. However, its naming convention is confusing me. It even can't correspond to itself in an object. For example, a dict object has a method named has_key and a method named popitem. So I need to check up on the function names frequently.

Front-end web development in 2018 is a fucking dumpster fire. 4 month old blog post guides are out of date, hipster toolchain APIs change monthly, npm can't find a module that is literally right there in its entirety in the fucking node_modules directory. JavaScript is love. JavaScript is life.

So yeah XML is still not solved in year 2018. Or so did I realize the last days.
I use jackson to serialize generic data to JSON.

Now I also want to provide serialization to XML. Easy right? Jackson also provides XML serialization facitlity similar to JAXB.

Works out of the box (more or less). Wait what? *rubbing eyes*

<User>
<pk>234235</pk>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</User>

Why is my groups property (java.util.Set) rendered as two separate elements? Who the fuck every though this is the way to go?

So OK *reading the docs* there is a way to create a collection wrapper. That must be it, I thought ...

<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groups typeCode="usergroup">
<pk>6356679041773291286</pk>
</groups>
<groups typeCode="usergroup">
<pk>1095682275514732543</pk>
</groups>
</groups>
</User>

What the fuck is this now? This is still not right!!!

I know XML offers a lot of flexibility on how to represent your data. But this is just wrong ...

The only logical way to display that data is:
<User typeCode="user">
<pk>2540591810712846915</pk>
<groups>
<groupsEntry typeCode="usergroup">
<pk>6356679041773291286</pk>
</groupsEntry>
<groupsEntry typeCode="usergroup">
<pk>1095682275514732543</pk>
</groupsEntry>
</groups>
</User>

It would be better if the individual entries would be just called "group" but I guess implementing such a logic would be pretty hard (finding a singular of an arbitrary word?).

So yeah theres a way for that * implementing a custom collection serializer* ... wait is that really the way to go? I mean common, am I the only one who just whants this fucking shit just work as expected, with the least amount of suprise?
Why do I have to customize that ...

So ok it renders fine now ... *writes test for it+
FUCK FUCK FUCK. why can't jackson not deserialize it properly anymore? The two groups are just not being picked up anymore ...

SO WHY, WHY WHY are you guys over at jackson, JAXB and the like not able to implement that in the right manner. AND NOT THERE IS ONLY ONE RIGHT WAY TO DO IT!

*looks at an apple PLIST file* *scratches head* OK, gues I'll stick to the jackson defaults, at least it's not as broken as the fucking apple XML:

<plist version="1.0">
<dict>
<key>PayloadOrganization</key>
<string>Example Inc.</string>
<key>PayloadDisplayName</key>
<string>Profile Service</string>
<key>PayloadVersion</key>
<integer>1</integer>
</dict>
</plist

I really wonder who at apple has this briliant idea ...

Fucking Webpack. This article is already out of date.

I'm working with dictionaries today so naturally all my variable names are making me chuckle:
threshDic
saveDic
cutDic
Etc. you get the picture, it's the little things that get you through a Friday slog.

Fuck this I need to ventilate.

Thinking about job change because maintaining and extending 3 years old codebase (flask project) is FUCKIN exhausting. It was badly written since start by someone who obviously didn't know much about python. (Going by commit history.)

Examples:
- if var != None / if var == None
- if var is not None / if var is None (well..)
- Returning self-parsed obscure JSONs from dict variable
- Serializing dictionaries into database by str() (both sqlalchemy and mysql support JSON format) - THEY ARE ALMOST UNUSABLE OTHER WAY AROUND (luckily, python can deal even with that)
- celery tasks, the way they are called they BLOCK the whole flask (not bad in itself, but if connection breaks there are no errors, nothing it just hangs)
- obscure generator/yielding that contains return of flask's response in itself
- creating fifteen thousands of variables one by one where they would look so nicely as dict keys, and hey they are then both MANUALLY SERIALIZED into returning dict by "%s" (string formatting) [okey, some of them are objecst like datetime but MATE WTF]
- many, many more, PEP lint shall not pass

I would rather deal with fresh startup owners wanting me to program unicorns in one week then trying to extend and manage zombie-like projects.

Nothing personal against the firm I actually like the place.

I hate this line with my soul.

The fact that I need to convert a dict to a string and then invoke the python parser to read it, feels so wrong!

anyone else giggle when someone says "this method takes a dict", or " wow that's a big dict", or really anything that sounds like they are talking about penises.

Contrary to popular belief, not everyone loves a big dict

Dear Python linters, why can't any of you implement some actual linting features? Like, say, consistent use of single or double quotes? Or dict() vs {}? How about indenting nested function calls? Forcing list / set / dict literals as multiline? Trailing commas?

And while I'm at it, why can't you handle dependencies properly? Say, separating linter & linter plugins from the remaining dependencies in a way where I don't have to manually remove them from the requirements lockfile every time?

Python list / dict comprehension, one of the numerous reason I truly love python. Simple and powerful abstraction

I am working on an AoK bot. It worked before but now it fails on me. It says: {'success': False, 'error': 'Invalid comment.'}

I don't know why.

This is the comment: "@retoor debugsemiss everything and nave the and resorts they're not paying much to clean a fucking roomic lolg creating of my phoprooting such is the quoting this kidle... Noh ot inuforian times fined the apposivy suistlondlan't by imprymarbygind. Metwary nate ?"

Call method:
```
async def post_comment(self, rant_id, text):
payload = dict(
rant_id=rant_id,
comment=text
)
payload.update(self.auth_params)
async with self.session.post(f'/api/devrant/rants/{rant_id}/comments',data=payload, params=self.auth_params) as resp:
print(await resp.json())
```

Someone has an idea why it's failing? Also tried it with hardcored rant_id and message.

The standard python Dict is NOT BLOODY ORDERED which I forgot meaning two hours of debugging why my CSV columns were in the wrong order.

PSA: Dict is not ordered as you would expect. Use collections.OrderedDict

How could I possibly understand this API without any explanation, data dict and example?

I declared it a Heisenbug!

So, basically I was starting multiple threads...
I was getting a list index out of range on line 268 which was a dict. Strange.
36 hours later, a lot of changes, I was still having the same error whatever I put on line 268, log, try, but when I got it on a comment... I lost it.
Restarted Pycharm.
Reset the branch to remote.
Everything worked fine.
Fuuuuuuuuuuu

Python rant. Why does my 500 line Flask file look like one long oblong, & why am I adding comments that say “end of function” in *any* programming language when surely clear visual marking of this should be built in? Why did I spent 2 hours debugging SQLite3 dict factory function only to find the issue was a misaligned indented function block that my linter hadn’t picked up on because it appeared to be a logic error. Why do you make my missing tab spaces into logic errors Python? And why does everyone insist that curly braces are just as bad? Not in my world Python. Also, stop returning obscure objects unannounced like I’m supposed to know about it in advance, and stop making me run an entire file only to find I have another mystery type error because I expected x and got y. I hate you Python!!

Python:
TypeError: unsupported operand type(s) for %: 'tuple' and 'dict'

Ugh there's a comma somewhere. I kinda appreciate how easy it is to make a tuple, but at the same time I don't. If there's no value after a comma with only one value behind it, could the linter at least mark it as a warning?

Is there ever a fucking reason to do a get_attrs call in python when you could just use a fucking explicit dict or just idk use the fucking typing system to implement a fucking interface? Like why the fuck should anyone ever be using get_attrs and strings to diddle objects?

What kind of people use `dict(a=1)` instead of `{"a": 1}` ?

Default dict that returns default dict on configparser to replace "if/try/nested .get()" to just "or"

In the end I had just
data = source or source1 or source2 or source3
