Load selected datasets into DataFrames
ODA-1 Order: #1 Explore Data and Find Signal Has Dependencies
Updated 1 month, 2 weeks ago
Guidance
Read each selected catalog dataset into a pandas Series/DataFrame using the appropriate reader (read_csv with explicit sep/header/index_col/na_values, read_json, read_fwf, or chunked read_csv(chunksize=) for very large extracts). Repair obviously sparse/irregular files (supply explicit names=, then ffill() a sparse category column before set_index()).
