I am not sure what is going wrong here.
import pandas as pd
class Data:
def __init__(self,database_name):
self.database_name=database_name
self.the_data_reader= getattr(Data, 'read_' database_name.lower())
def read_data(self):
self.the_data_reader()
# Parametros basicos da base
def read_opnosis(self):
self.texts_df=pd.DataFrame(columns=['name','text'])
self.summaries_df=pd.DataFrame(columns=['name','summary'])
if __name__ == '__main__':
data=Data('opnosis')
data.read_data()
However, I am receiving this error:
TypeError: read_opnosis() missing 1 required positional argument: 'self'

I think you need to use eval
function.

data.read_data()
Hope it could help.
