Define a function named read_csv_header with one parameter. This parameter will be a csv reader object (e. g., the value returned when calling the function csv. reader). The first row read using the parameter is the file's header row. The header row contains the keys for the data stored in the CSV file. This function must return a list containing the strings from that header row. The function parameter will be a csv reader object and not a string. This means you do not need the with..as nor create the csv reader in your function, but this will be done in the code calling your function. For example, to execute read_csv_header using a file named "smallDataFile. csv" you would write the following code: with open("smallDataFile. csv") as f_in: csv_r = csv. reader(f_in) header = read_csv_header(csv_r) You would then want to include code to check that header had the expected value. For example, suppose the first line of the file being read by csv_r was: tow_date, tow_reason then the call read_csv_header(csv_r) would need to return: ['tow_date','tow_reason'].
