start : int, optional
            Start position for slice operation.
        stop : int, optional
            Stop position for slice operation.
        step : int, optional
            Step size for slice operation.

        Returns
        -------
        Series or Index of object
            Series or Index from sliced substring from original string object.

        See Also
        --------
        Series.str.slice_replace : Replace a slice with a string.
        Series.str.get : Return element at position.
            Equivalent to `Series.str.slice(start=i, stop=i+1)` with `i`
            being the position.

        Examples
        --------
        >>> s = pd.Series(["koala", "dog", "chameleon"])
        >>> s
        0        koala
        1          dog
        2    chameleon
        dtype: object

        >>> s.str.slice(start=1)
        0        oala
        1          og
        2    hameleon
        dtype: object

        >>> s.str.slice(start=-1)
        0           a
        1           g
        2           n
        dtype: object

        >>> s.str.slice(stop=2)
        0    ko
        1    do
        2    ch
        dtype: object

        >>> s.str.slice(step=2)
        0      kaa
        1       dg
        2    caeen
        dtype: object

        >>> s.str.slice(start=0, stop=5, step=3)
        0    kl
        1     d
        2    cm
        dtype: object

        Equivalent behaviour to:

        >>> s.str[0:5:3]
        0    kl
        1     d
        2    cm
        dtype: object
