pandas.Panel.reindex¶
- Panel.reindex(items=None, major_axis=None, minor_axis=None, **kwargs)¶
Conform Panel to new index with optional filling logic, placing NA/NaN in locations having no value in the previous index. A new object is produced unless the new index is equivalent to the current one and copy=False
Parameters: items, major_axis, minor_axis : array-like, optional (can be specified in order, or as keywords)
New labels / index to conform to. Preferably an Index object to avoid duplicating data
method : {‘backfill’, ‘bfill’, ‘pad’, ‘ffill’, None}, default None
Method to use for filling holes in reindexed DataFrame pad / ffill: propagate last valid observation forward to next valid backfill / bfill: use NEXT valid observation to fill gap
copy : boolean, default True
Return a new object, even if the passed indexes are the same
level : int or name
Broadcast across a level, matching Index values on the passed MultiIndex level
fill_value : scalar, default np.NaN
Value to use for missing values. Defaults to NaN, but can be any “compatible” value
limit : int, default None
Maximum size gap to forward or backward fill
takeable : boolean, default False
treat the passed as positional values
Returns: reindexed : Panel

>>> df.reindex(index=[date1, date2, date3], columns=['A', 'B', 'C'])
