>>> import mars.tensor as mt >>> import mars.dataframe as md >>> s = md.Series(['1. Ant. ', '2. Bee!\n', '3. Cat?\t', mt.nan]) >>> s.execute() 0 1. Ant. 1 2. Bee!\n 2 3. Cat?\t 3 NaN dtype: object
>>> s.str.strip().execute() 0 1. Ant. 1 2. Bee! 2 3. Cat? 3 NaN dtype: object
>>> s.str.lstrip('123.').execute() 0 Ant. 1 Bee!\n 2 Cat?\t 3 NaN dtype: object
>>> s.str.rstrip('.!? \n\t').execute() 0 1. Ant 1 2. Bee 2 3. Cat 3 NaN dtype: object
>>> s.str.strip('123.!? \n\t').execute() 0 Ant 1 Bee 2 Cat 3 NaN dtype: object
