edmt.base.ExtractCSV(row: dict | pandas.Series, col: str, max_retries: int = 3, timeout: int = 15) → pandas.DataFrame | None¶

Fetches a CSV file from a URL specified in a given column of a metadata record.

This function retrieves a CSV file from the URL found in the specified column (col) of the input row, parses it into a pandas DataFrame, and returns the result. It includes retry logic with exponential backoff to handle transient network errors.

Parameters:

row (dict or pandas.Series) -- A metadata record containing a URL string in the column specified by col.
col (str) -- The key or column name in row that contains the URL to the CSV file.
max_retries (int, optional) -- Maximum number of retry attempts in case of failure. Defaults to 3.
timeout (int or float, optional) -- Timeout for each HTTP request in seconds. Defaults to 15 seconds.

Returns:

A pandas DataFrame containing the parsed CSV data if successful.
None if the URL is missing, invalid, or if all retry attempts fail.

Return type:

pandas.DataFrame or None

Raises:

None --
