building a distributed async python backend rn messing with asyncio event loops, concurrent workers, multithreading, websocket streams, REST APIs, request queues, proxy rotation, rate-limit handling, JSON serialization, regex parsing, redis caching, postgres, connection pooling, dependency injection, docker containers, CI/CD pipelines, exception handling, retry logic, exponential backoff, memory profiling and some absolutely fucked race conditions

i hate how coding in python has mentally changed my life i remember back in the day when i was just a normal guy with a normal life now im up at 4am debugging some async asyncio multithreaded api scraper because my requests are getting rate limited and throwing 403s while im staring at stack traces rewriting functions fixing dependencies and wondering why the fuck my virtual environment broke again

No, thats not the point

Python

15 September 2026 11:55

I just told you
What other information you need?

Python

15 September 2026 11:45

If you are doing financial math - use Decimal

If you are calculating a trajectory for a rocket, use external libraries

DO NOT use Fraction to represent floating point numbers

That's it

Python

15 September 2026 11:42

Fractions get slower and slower as you work with them, and are rarely used for representing floating point numbers

Python

15 September 2026 11:38

float(decimal.Decimal('.1') + decimal.Decimal('.2'))
and
float(fractions.Fraction('0.1') + fractions.Fraction('0.2'))

so will should i use the fraction?

Python

15 September 2026 11:35

If you were to calculate floats for currency, prices, legal and tax documents
Then yes, you use Decimal
But as its software based and on base-10 rule, it makes it slower to work with then other solutions

But for high precision and high speed calculation needed for example in data science or calculating a rocket orbit
You need something with high precision, where the error at the 50th decimal place does not affect the outcome

So it comes down to what you are actually calculating

Python

No, that's not what we do here.

What are you calculating?

Python

14 September 2026 20:16

why library i listen we should to do

Decimal("0.1") + Decimal("0.2")

Python

13 September 2026 07:36

That was too easy, thx for the assist

Python

13 September 2026 07:35

In a windows computer, as any other program, you download the installer, open it and follow the assistant

what are you working on ?

Python

15 September 2026 12:05

ok bye leave this topics is overkilling me for now

Maybe the rocket science floating i will never need to learn

i just want to be learn simple website making Hosting and sell website 😅

Python

15 September 2026 12:01

i think to start using the fast speed decimal calculations for my normal apps also? will it ok really?

Python

15 September 2026 11:51

so which u will say i should learn, so that from now i will Learning Using simple fast speed of floating calculation for my own shopping app, school apps like this?

Python

15 September 2026 11:44

you have just stop my mouth 😅 and just push me into the sea of confusion

Python

15 September 2026 11:38

Read again the above message
And decide for yourself

And float(Decimal) does not make apsolutly no sense

Python

15 September 2026 11:37

so n past u say :-> for all price, tax tables i should to always use the decimal.Decimal. from then i switched to this for all my code.
now what u say i will use in real production case. !

Python

15 September 2026 11:20

i was calculating

Decimal("0.1")+Decimal("0.2")
decimal adding without causing any floating problem without using any external library!

Python

14 September 2026 21:49

Can anyone help me with python's technology to build an ai driven app

Python

14 September 2026 21:43

Yes, we have established that already.

Python

14 September 2026 20:28

i means, as he says we will use library here for this!!!
but i found normally with the Decimal we can solve the float problem. so ehat rhe library be say to use

Python

14 September 2026 08:31

That's the case with all programming languages
Floating numbers are handled with a binary representation, so there will be an overflow at times
There are libraries designed to handle that though

Python

thanks all of you guys

Use Decimal() from decimal module.
