Python multiline lines

There is some PEP8 saying that files shouldn't be more than 79 columns of text, which I will agree with.</p>

While building with nix, I come across its python linter shananagans. I make my main nix flake have built-in scripts, for python we use writers.writePython3Bin</em>, which lets me add dependancies and script text all in one place.</p>

This goes through the python linters every time its rebuilt. It's very strict by default, and you can relax the rules, but I don't want to. The rules have coerced me into learning new things about python.</p>

I don't like vibe coding where it farts out code all day. I rather know whats happening. So, after months of messing with llm coding, I've learned to keep code it writes small. Still, it gets out of hand, so I am constantly fighting for it not to write so much code.</p>

It wrote my newest version of ai.py which is a simple script to take in some text (or image) and in the background give it to an llm, write out the output on the drive when its finished. I don't have to see it streaming. It's totally possibly its 100% trash, or its usual sneaky gaslighting ways, doing just enough to run, but bad things are suddly and stratigically hidden. (not really stratigically but its very good at gaslighting).</p>

The LLM wrote lines that are out of the PEP8 spec</a>. There were a bunch over 79 columns of text, which the linter wont pass unless you relax it.</p>

I asked an llm, and it would give me new formatting that fit. This is what it said:</p>

Depending on your preference for readability, here are the three best ways to break this line according to PEP 8 standards.</p>
Option 1: Using Parentheses (Recommended)</h3>
Wrapping the expression in parentheses allows you to break the line wherever you like without using backslashes. This is the cleanest and most "Pythonic" approach.</p>
image_path = ( ingest_path if ingest_path and is_image_file(ingest_path) else None ) </code></pre>Option 2: Standard if/else</code> Block</h3> If you are worried about the line length or the complexity of the one-liner, expanding it into a standard block is the most readable for other developers.</p> if ingest_path and is_image_file(ingest_path): image_path = ingest_path else: image_path = None </code></pre> Option 3: Backslash Continuation</h3> You can use a backslash to tell Python the line continues, though this is generally less preferred than Option 1.</p> image_path = ingest_path if ingest_path and \ is_image_file(ingest_path) else None </code></pre> Which one should you choose?</h3> Choose Option 1</strong> if you want to keep the logic concise but satisfy the linter.</li> Choose Option 2</strong> if this code is part of a critical section where clarity and debuggability are more important than brevity.</li> </ul> </blockquote> I liked the Option #2. It looks better, is shorter, and easier to see what it is actually doing. It's also made me open up the PEP8 doc and start reading it. It's mad this doc much more interesting to read, it has lots of cool syntax tricks that I wouldn't even thought of. I think any one writting or reading Python is going to get a boost reading that PEP8 Python Style guide.</p> References</h2> PEP 8 – Style Guide for Python Code</strong> https://peps.python.org/pep-0008/</a></li> </ul>
