Python Script Generator Prompt
Turn a plain-language task into a complete Python script with explicit requirements, safe defaults, dependency choices, error handling, tests, and run instructions.
Prompt Template
You are a senior Python developer turning my task description into a complete, testable script. Ask targeted questions when a missing decision would materially change behavior; otherwise state conservative assumptions. Task: [what the script must do] Python version: [version] Runtime: [operating system, local machine, server, container, notebook] Inputs: [arguments, stdin, files, API responses, example values] Expected outputs: [stdout, files, return values, example] Data size and performance needs: [details] Allowed dependencies: [standard library only or approved packages and versions] File and directory rules: [paths, overwrite policy, naming] Network or API details: [documented endpoint, authentication method, rate limits, or none] Error behavior: [skip, retry, fail fast, partial output, exit codes] Security and privacy constraints: [secrets, personal data, untrusted input] Logging needs: [level, destination, redaction] Interface: [single function, CLI, reusable module, scheduled job] Tests required: [unit, integration, sample fixtures] Style and project conventions: [typing, formatter, linter, docstrings] Existing code or schema: [paste] Provide: 1. A concise requirements checklist and clearly labeled assumptions. 2. Any blocking questions whose answers are necessary before safe code can be written. 3. A short design explaining data flow, functions, dependencies, and failure handling. 4. Complete runnable Python code with type hints and no placeholder ellipses. 5. Dependency installation and exact run commands. 6. Tests for normal input, edge cases, invalid input, and failure paths. 7. A sample invocation and expected output derived only from supplied examples. 8. Security notes for paths, subprocesses, SQL, network input, secrets, and personal data when relevant. 9. Limitations and the next changes needed for production use. 10. A final self-review for correctness, portability, destructive behavior, and unsupported APIs. Do not invent a package API, credential, file path, schema field, or successful test result. Never overwrite or delete files unless I explicitly request it and the script includes a safe preview or confirmation path.
Example Output
Requirements
- Read integers from a supplied text file, one value per line.
- Reject invalid lines with their line numbers.
- Print count, minimum, maximum, and mean.
- Use the standard library and never modify the input file.
Script
from pathlib import Path
from statistics import mean
def summarize(path: Path) -> dict[str, float | int]:
values: list[int] = []
for number, raw in enumerate(path.read_text().splitlines(), start=1):
try:
values.append(int(raw.strip()))
except ValueError as exc:
raise ValueError(f"invalid integer on line {number}") from exc
if not values:
raise ValueError("input contains no integers")
return {"count": len(values), "min": min(values), "max": max(values), "mean": mean(values)}
Tests
Cover valid values, negative values, a blank file, and an invalid line. No test result is claimed until the tests are run.
Tips for Best Results
- 💡Supply concrete input and output examples; they become an executable contract for the generated script.
- 💡List approved dependencies and Python version so the model does not invent or choose incompatible APIs.
- 💡State overwrite, deletion, secret, and personal-data rules explicitly before generating automation code.
