"""Helper function to create a dataframe from yaml fields to get used for
|
||||
all three configs: csv, excel, and supplemental codebook information yaml
|

|
||||
This function does:
|
||||
1. Creates a dictionary to be converted to a dataframe. Pandas easily converts
|
||||
dictionaries of the form {column_name: [value_1, value_2, value_3]} to
|
||||
dataframes, where column_name is the name of the column and the list of values
|
||||
is (by numerical index) the values for the series.
|
||||
Column names here are dictated by the fields_to_store_in_codebook list, a named
|
||||
tuple that includes the name of the field in the yaml and the name the field will
|
||||
take in the codebook. For example, both the csv and excel configs use the name "label",
|
||||
but in the codebook, we want one of these fields to be "csv_label" and the other
|
||||
to be "excel_label".
|
||||
2. Cycles through the fields specified in the yaml fields list. Each field includes
|
||||
some additional details, and so the function appends that information to the dictionary
|
||||
lists, as described above. If the field is missing, appends a null value so that the row's
|
||||
value is blank. This is an artifact of constructing a dataframe from a dictionary of lists.
|
||||
3. Returns a dataframe indexed by the column name used in CEJST data (i.e., the
|
||||
score name field that is consistent across all yamls and in our own usa.csv).
