Pоwer Generаtоrs Assume the functiоn cell(row_idx, col_nаme) (whose inputs аre the row index and column name of the data file) extracts data located at a specific row and column from a data file. The following table contains this data: - entity_id entity_name latitude longitude net_winter_capacity 0 4247 Du baly 46.5 -90.5 13 1 123 Saxon FALL 40 -88 16 2 456 Alexander Age 45 -93 5 3 789 Brownie 42 -92 22 4 456 Alexander Age 45 -93 10 For example, the output of cell(0, "entity id") is 4247. The types of the outputof the cell function for each column name is shown below:• entity id: int• entity name: str• latitude: float• longitude: float• net winter capacity: int
