Answer 1

You can try this (assuming your csv is called filename.csv):

df = pd.read_csv('filename.csv')

df['LABELS'] = df.LABELS.apply(lambda x: x.strip('()').split(','))

>>> df
   ID                               LABELS
0   1  [1.0, 2.0, 2.0, 3.0, 3.0, 1.0, 4.0]
1   2  [1.0, 2.0, 2.0, 3.0, 3.0, 1.0, 4.0]
