Before

Write a Python script to process my CSV

Too vague—AI has to guess what you want

After

Write a Python 3.11 script to process a CSV file with columns: date, product_name, revenue, units_sold. The script should: load the file with pandas, clean nulls and data type errors, calculate total revenue and average units per product, output a summary CSV and print a brief report to the terminal. Add docstrings and inline comments. Handle FileNotFoundError gracefully.

Specific, clear, ready to use

What makes the strong prompt better?

Python version specified prevents outdated syntax

Column names provided means the script is immediately runnable after minor edits

Error handling instruction prevents a script that crashes on basic edge cases

Frequently asked questions

What is the best AI prompt to write a python script?

+
A great prompt to write a python script is specific about the output you want. Use this template as a starting point: "Write a Python 3.11 script to process a CSV file with columns: date, product_name, revenue, units_sold. The script should: load the file with pandas, clean nulls and data type errors, calculate total revenue and average units per product, output a summary CSV and print a brief..." Adjust the specifics — audience, tone, length — to match your situation.

Which AI tool works best to write a python script?

+
Claude handles this prompt well, but the same structure works in Claude, Gemini, and other modern LLMs. The reason it works isn't the tool — it's the level of context and constraint in the prompt itself.

Why does my AI a python script come out generic?

+
Generic output almost always traces back to a vague prompt like "Write a Python script to process my CSV". To fix it: add audience, tone, length, examples to follow, and things to avoid. The strong prompt above shows each of those in action.

Can I use this prompt commercially?

+
Yes — these are templates, not protected content. Adapt them freely for client work, internal use, or production tools. Output rights depend on the AI tool's terms (ChatGPT, Claude etc each set their own).
