Python Quiz: The "Late Binding" Trap 🐍

Let’s test your understanding of Python closures and scoping. What is the output of the following code snippet?

def create_multipliers():
    multipliers = []
    for i in range(5):
        def multiplier(x):
            return x * i
        multipliers.append(multiplier)
    return multipliers

funcs = create_multipliers()
print([f(1) for f in funcs])

Can I get a Sugesssion:-

Why they say to use @dataclass, even i think to use pydantic 's BaseModel to represent data in my domain entities, even i will use pydantic all over my repo as a must need library for working with class easily.

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

I am the beginner and I want to learn python

Python

17 September 2026 06:53

If u seriously wanna learn Python, my 2 cent is to go this path:
1- Read Python Crash Course book && Do ALL the practices & coding there (mocking, changing some segments, re-doing the practices on ur own)
2- Read Effective Python (125 specific ways ...) not the old version (90 specific ways ...) & apply ur learning about best practices onto what u've done in Python Crash Course.

Avoid getting lost in thousands of articles out there.

Once u learn everything in those 2 books, u're way better than lots of Python devs in writing correct & idiomatic Python.

But if u're not genuinely interested & just wanna look cool, we're in post-llm era. Easy to look like magicians by a couple of prompts. So, don't waste ur time.

Read again the above message
And decide for yourself

And float(Decimal) does not make apsolutly no sense
