示例

>>> import maxframe.dataframe as md
>>> s = md.Series(["a", "b", "c"])
>>> s.execute()
0    a
1    b
2    c
dtype: str

使用单个整数重复 Series 中的字符串

>>> s.str.repeat(repeats=2).execute()
0    aa
1    bb
2    cc
dtype: str

使用整数序列重复 Series 中对应的字符串

>>> s.str.repeat(repeats=[1, 2, 3]).execute()
0      a
1     bb
2    ccc
dtype: str
