Prompt
Write a Python function `column_sum(csv_text, column)` that parses `csv_text` (a string of CSV
with a header row) and returns the sum of the named `column` as a float.
Values in the column are numeric. Handle quoted fields containing commas correctly (standard CSV
quoting). If the column name is not in the header, raise `KeyError`.
Put it in a single Python code block. It will be imported as `from solution import column_sum`.when to use it
Community prompt sourced from the open-source GitHub repo Green-PT/honey-for-devs (MIT). A "Prompt" style prompt — adapt the placeholders and specifics to your task. Imported as-is and not independently retested here, so check the output before relying on it.
