Examples
>>> import mars.dataframe as md >>> s = md.Series(["koala", "dog", "chameleon"]) >>> s.execute() 0 koala 1 dog 2 chameleon dtype: object
>>> s.str.slice(start=1).execute() 0 oala 1 og 2 hameleon dtype: object
>>> s.str.slice(start=-1).execute() 0 a 1 g 2 n dtype: object
>>> s.str.slice(stop=2).execute() 0 ko 1 do 2 ch dtype: object
>>> s.str.slice(step=2).execute() 0 kaa 1 dg 2 caeen dtype: object
>>> s.str.slice(start=0, stop=5, step=3).execute() 0 kl 1 d 2 cm dtype: object
Equivalent behaviour to:
>>> s.str[0:5:3].execute() 0 kl 1 d 2 cm dtype: object
