Best Python setup for young programmer
We got my young (13 y/o) sibling (who has a strong math interest) a computer, so naturally I bought the [Python for Kids](https://www.nostarch.com/pythonforkids) book (as well as [Doing Math With Python](https://www.nostarch.com/doingmathwithpython)).
The problem now is the python setup. I initially installed Anaconda and PyCharm, but realized that it was a bit more complicated (for a 13 year old) that I anticipated (virtual environments and what-not).
Whats the recommended python setup for kids (on windows 10). Im assuming IDLE? But what about installing modules? Is there any super user friendly IDE (or the like) software that they can use?
Edit: the issue isn't editing code, Notepad++, atom, sublime, or any of non-IDE text editors should do fine. The issue is easily (think push-button) running the code. I learned C/C++ on Bloodshead C++ IDE if that gives a better picture of what I'm thinking.

Webapp with DRF: ending up with too many view-specific serializers?
As stated in the title, my webapp is built on DRF, and though I **love** how easy serializers are to use, I feel like I'm almost creating specialized serializers for the data each view needs. The alternative seems to be to have one serializer that returns an overkill amount of data and have the front end deal with sorting out what it needs vs doesnt need.
for example: I have a Client (C) model and it has a related OnboardingStatus (OS) model and a AccountStatistics (AS) model. I can either make 3 serializers to send C alone/C+OS/C+AS
**OR** I can make 1 serializer that sends C+OS+AS all the time. (I simplified here, my data is bigger and a bit more nested)
How do the fine redditors of /r/django deal with this issue? Is there a smarter way that I'm not seeing?

Can fields have attributes?
A quick introduction for my question:
Creating a financial app. Main model is Company, with a child called Balancesheet. In the balancesheet I have fields like "cash", "goodwill" and other accounting stuff.
Items in the balancesheet can be classified into financial and operating assets. Cash is a financial asset. I want a way to give cash that attribute. And other fields might have the attribute of an operating asset.
Do I really have to create a child model for every item on the balancesheet just to give them this attribute?

Creating a .exe file from a .py file keeps failing
I'm about to lose my mind here. I've become quite proficient in Python over the past few months but for the life me I cannot create a .exe file from my Python files. I have tried watching dozens of YouTube tutorials, looked at 100s of examples, websites and forums and absolutely nothing works. I tried using setup.py examples from the internet, pyinstaller, cx_Freeze, pyBuilder, py2exe and pynsist.
Pynsist is the only one that never gave me errors but it did not create a .exe file for my application. All the other applications either give me blank folders, IndexError: tuple out of range errors, or no commands supplied errors. I tried the command: python setup.py build and the exe it created just produces a ModuleNotFoundError message.
What could I be doing wrong or where can I go to get this done properly. Because right now I'm beginning to think this impossible to do. Is there a tool that can be used to do this that ACTUALLY works and actually explains how to do this? What can I do?
I am running Python 3.6, and the ".exe" files these modules create only seem to work on my computer, not on anyone elses', even if they have Python on them. At best it opens Code Writer on other computers I have tested my .exes on.

ELI5: What are the benefits of Redis, and how do you use it with RDBMS?
Let's say I have a PostGIS database with a lot related models. Would I have to basically aggregate that data into NoSQL type models to store them in redis? At what point do you move the data from models to Redis?
Note that I am a redis nooblet, so my understanding may be wrong... Just trying to figure out if it even makes sense for me to learn and implement redis. Thanks.
Ninja edit: Also, I guess geographical searches should still be handled by Django's GIS rather than me rewriting it all in Redis, if I go ahead and use that. How do you guys manage it?

[AF] Convert Oracle query to SQLAlchemy ORM
I have been trying to convert Oracle query to SQLAlchemy specifically ORM Here is the SQL I want to convert:
SELECT p.id,
p.name,
p.address,
to_char(t.s_time, 'mm/dd/yyyy hh:mi:ss AM') date_s,
t.date_h,
FROM p_table p,
(SELECT t_id,
dept,
ROW_NUMBER() OVER(PARTITION BY t_id ORDER BY dept) AS row_id
FROM t_table
WHERE t_id = :t_id
AND actual_time IS NULL) t
WHERE p.id = :id_var
AND row_id = 1
ORDER BY date_c DESC
Here is my attempt on converting this:
row_id = func.row_number().over(partition_by=TModel.t_id, order_by=TModel.dept)
sub_query = db.session.query(TModel.t_id, TModel.dept)\
.add_column(row_id)\
.from_self().filter(row_id == 1)\
.filter(TModel.t_id == t_id)\
.filter(TModel.actual_time == None)\
.label("sub_query")
q = db.session.query(PModel.id, PModel.name,
PModel.address, TModel.s_time, TModel.temp, sub_query)\
.filter(PModel.t_id == t_id)\
.order_by(PModel.date_complete.desc())\
.all()
print q
It seems I didn't correctly convert it into sqlalchemy it returns more than it is expecting for example running the SQL (5 rows) vs SQL(20+ rows) . Any help is greatly appreciated. Thank you!

[D] What type of Asimov-style rules would robot hosts have in HBO's Westworld?
>In the HBO series Westworld, a Host is an artificially created being, an android or artificially created animal. All of the animals (except for flies) in Westworld are hosts.
>The hosts are built to act out both storylines and narratives in the park by interacting with each other and with guests. They are designed to be incapable of permanently hurting any living non-host.
>At least some hosts are given a narrative to follow, and it may be that all hosts have a narrative to follow.
>Narratives are the stories that guests can participate in within the park. These stories are part of the entertainment of the guests. (Hosts follow their own story lines that loop, or repeat. The host's story lines can be part of guest narratives. There have been instances when hosts have broken away from their loops.)

Sqlalchemy for Mysql vs postgres
Hi Im learning to program(first year CompSci student) and Im trying to teach myself how to make a website backed by a database. So far it is proving to be a harder nut to crack than I had anticipated, and definitely a learning experience.
I did a pretty cool tutorial where I scraped some facebook data with their api and stored it in a Mysql database, That was pretty cool. Now next step for my plan will be connecting to that database and getting the info out of it to use. for that end I found sqlalchemy and flask. Seems pretty great and I found a pretty great tutorial :
https://auth0.com/blog/sqlalchemy-orm-tutorial-for-python-developers/
But they use a postgres database! As far as I understand the whole purpose of sqlalchemy is so that the language will be the same for connecting to any database. Am I correct? If not Im thinking this whole thing might be a bit too ambitious for my current skill level! Oh well! Im open to any and all suggestions :)
TLDR: can i use sqlalchemy with a mysql database just like a postgres database?
