Python prompts
Python prompts across the real day-to-day — scripts, data wrangling, FastAPI services, tests — written with type hints and error handling in the ask, not bolted on after.
Every prompt lists the exact tool and version it was tested against.
Turn a plain-English function spec into fully type-hinted PythonA prompt that converts a rough description of what a function should do into PEP 484-typed Python with explicit edge-case handling and a docstring, instead of untyped happy-path code.ChatGPT (GPT-5.1)Claude (Sonnet 4.6)2026-07-14Scaffold a FastAPI endpoint with real validation and status codesA prompt that turns an endpoint requirement into a complete FastAPI route with Pydantic v2 models, correct HTTP status codes, and dependency-injected services, instead of a bare route stub returning a dict.GitHub Copilot ChatCursor 2.12026-07-20Generate a pytest suite that tests behavior, not implementationA test-generation prompt that requires parametrized cases, isolated external dependencies, and named edge-case coverage, instead of a handful of near-duplicate happy-path tests.Claude CodeGitHub Copilot Chat2026-07-18Turn a messy DataFrame into a documented, reproducible cleaning pipelineA prompt for building a pandas cleaning pipeline as small, named, chainable functions with logged row drops and a schema check at the end, instead of one long unexplained block of reassignments.ChatGPT (GPT-5.1)Claude (Sonnet 4.6)2026-07-25Turn a one-off Python script into a proper CLI toolA prompt that converts a script with hardcoded values or manual sys.argv indexing into a Typer or Click CLI with real help text, validation, and exit codes.Claude CodeChatGPT (GPT-5.1)2026-07-28Refactor blocking Python code to async without breaking it silentlyA prompt for converting synchronous I/O-bound code to async/await that separates what genuinely benefits from async, wraps unavoidable blocking calls correctly, and checks every caller — instead of prefixing every function with async def.Claude CodeChatGPT (GPT-5.1)2026-08-02Design Pydantic v2 models that validate a real domain, not just shapesA prompt for designing Pydantic v2 models with field constraints, cross-field validators, and deliberate optional/required decisions from a description of real-world business rules.Claude CodeChatGPT (GPT-5.1)2026-07-21Diagnose a Python dependency or virtual environment conflict systematicallyA structured diagnostic prompt for dependency and venv breakage that requires a stated root-cause hypothesis and cited evidence before proposing a fix, instead of jumping straight to pip install --upgrade.ChatGPT (GPT-5.1)Claude (Sonnet 4.6)2026-07-11Find out why Python code is actually slow before optimizing itA profiling-first prompt that requires naming the real bottleneck category with a specific tool and command before suggesting any optimization, instead of guessing at generic speedups.Claude CodeChatGPT (GPT-5.1)2026-07-30Package a Python project for real distribution with pyproject.tomlA prompt for producing a complete, modern src-layout package with a real pyproject.toml, dev/test dependency groups, and a verified build step, instead of a bare setup.py or an incomplete pyproject stub.Claude CodeChatGPT (GPT-5.1)2026-08-01Build a data validation pipeline that quarantines bad records instead of crashing on themA prompt for a validation layer on an ingestion pipeline that separates "reject the whole batch" from "quarantine the bad row and keep going," backed by one named schema instead of scattered ad hoc checks.ChatGPT (GPT-5.1)Claude (Sonnet 4.6)2026-07-17Get Python code reviewed for idiomaticity, not just correctnessA review prompt that separates "is this correct" from "is this how an experienced Python developer would write it," with a closed set of idiom categories so the review surfaces real foot-guns instead of restating the code.Claude CodeChatGPT (GPT-5.1)2026-07-27
