An example of a simple CSV Importer
|
|
===================================
|
|
Suppose you have a csv dataset containing only the trajectories, three variables labels and cardinalites.
|
|
Then the resulting importer that inherit and extends AbstractImpoter would be:
|
|
|
|
.. code_block:: python
|
|
class CSVImporter(AbstractImporter):
|
|
|
|
def __init__(self, file_path):
|
|
self._df_samples_list = None
|
|
super(CSVImporter, self).__init__(file_path)
|
|
|
|
def import_data(self):
|
|
self.read_csv_file()
|
|
self._sorter = self.build_sorter(self._df_samples_list[0])
|
|
self.import_variables()
|
|
self.import_structure()
|
|
self.compute_row_delta_in_all_samples_frames(self._df_samples_list)
|
|
|
|
def read_csv_file(self):
|
|
df = pd.read_csv(self._file_path)
|
|
df.drop(df.columns[[0]], axis=1, inplace=True)
|
|
self._df_samples_list = [df]
|
|
|
|
def import_variables(self):
|
|
values_list = [3 for var in self._sorter]
|
|
# initialize dict of lists
|
|
data = {'Name':self._sorter, 'Value':values_list}
|
|
# Create the pandas DataFrame
|
|
self._df_variables = pd.DataFrame(data)
|
|
|
|
def build_sorter(self, sample_frame: pd.DataFrame) -> typing.List:
|
|
return list(sample_frame.columns)[1:]
|
|
|
|
def import_structure(self):
|
|
data = {'From':['X','Y','Z'], 'To':['Z','Z','Y']}
|
|
self._df_structure = pd.DataFrame(data)
|
|
|
|
def dataset_id(self) -> object:
|
|
pass
