Update CsvObject

[Henrike-Schwenn]

• [x] Decide: Methods in constructor?
• [ ] Check pd.readcsv settings
• [ ] Why does it return values as FALSE?
• [ ] Does that mean the function checks whether the values are numerical (TRUE) or not (FALSE)?
• [ ] Decide whether to keep this feature or not
• [ ] Turn all values into numerical values
• [ ] Save dataframe into object (feather)

Don't define methods in a constructor. Set them as self.method() and define them afterwards.

class Plane:
    def __init__(self):
        self.wings = 2

        # fly
        self.drive()
        self.flaps()
        self.wheels()

    def drive(self):
            print('Accelerating')

    def flaps(self):
            print('Changing flaps')

    def wheels(self):
            print('Closing wheels')

class CsvObject:

    def __init__(self, pathCsvDataset="Directory leading to a csv file", csvDataset="Csv file to be read", csvDataframe="Name of Dataframe"):
        self.pathCsvDataset = pathCsvDataset
        self.csvDataset = csvDataset
        self.csvDataframe = csvDataframe
        self.CreateDataframe()

    def CreateDataframe(self):
        os.chdir(self.pathCsvDataset)
        #TODO: Verify data format csv
        return self.csvDataframe == pandas.read_csv(self.csvDataset)

Works

TrainingSet.CreateDataframe()
       datetime  season  holiday  ...  casual  registered  count
0         False   False    False  ...   False       False  False
1         False   False    False  ...   False       False  False
2         False   False    False  ...   False       False  False
3         False   False    False  ...   False       False  False
4         False   False    False  ...   False       False  False
