xorbits.pandas.Index.to_frame#

Index.to_frame(index: bool = True, name=None)[源代码]#

Create a DataFrame with a column containing the Index.

参数

  • index (bool, default True) – Set the index of the returned DataFrame as the original Index.

  • name (object, defaults to index.name) – The passed name should substitute for the index name (if it has one).

Index.to_series

Convert an Index to a Series.

Series.to_frame

Convert Series to DataFrame.

实际案例

>>> idx = pd.Index(['Ant', 'Bear', 'Cow'], name='animal')  
>>> idx.to_frame()  
       animal
animal
Ant       Ant
Bear     Bear
Cow       Cow

By default, the original Index is reused. To enforce a new Index:

>>> idx.to_frame(index=False)  
    animal
0   Ant
1  Bear
2   Cow

To override the name of the resulting column, specify name:

>>> idx.to_frame(index=False, name='zoo')  
    zoo
0   Ant
1  Bear
2   Cow
