AI prompts for python

Write a Python script that [describe the task]. Input: [describe input data/format] Output: [describe expected output] Python version: [e.g. 3.12] Libraries allowed: [e.g. standard library only, pandas] Requirements: clear variable names, comments for non-obvious parts, error handling for [likely problems], and a small example of how to run it. After the code, explain how it works in plain English and list any assumptions you made.

I have a CSV with these columns and sample rows: [paste column names and 5 sample rows — remove personal data] Problems I see: [e.g. missing values, mixed date formats, duplicates] Goal: [e.g. monthly sales totals by region] Write pandas code that loads the file, fixes these problems step by step with comments explaining each choice, and produces the goal output. Print row counts before and after each cleaning step so I can check nothing was lost unexpectedly.
