How to assign input file name as logger name

[Mekala]

The file name should be automatically align to csv file name in:

data.read_data(csvfile = r'HATY.csv', cols = 'col1', opmode = 'NOM')
here HATY
if I pass:
data.read_data(csvfile = r'XYZ.csv', cols = 'col1', opmode = 'NOM')
filename=('XYZ'+datetime.today().strftime('%Y%m%d_%H%M%S')+'.txt')

but I don't want to manually do it, but automatically grep the csv file name from

data.read_data(csvfile = r'XYZ.csv', cols = 'col1', opmode = 'NOM')
