Convert a columns of string to list in pandas

You can use ast.literal_eval, which will give you a tuple:

import ast
df.LABELS = df.LABELS.apply(ast.literal_eval)

If you do want a list, use:

df.LABELS.apply(lambda s: list(ast.literal_eval(s)))

Use str.strip and str.split:

df['LABELS'] = df['LABELS'].str.strip('()').str.split(',')

But if no NaNs here, list comprehension working nice too:

df['LABELS'] = [x.strip('()').split(',') for x in df['LABELS']]
