pandas.SparseArray.fillna¶
-
SparseArray.
fillna
(value=None, method=None, limit=None)[source]¶ Fill missing values with value.
Parameters: - value : scalar, optional
- method : str, optional
Warning
Using ‘method’ will result in high memory use, as all fill_value methods will be converted to an in-memory ndarray
- limit : int, optional
Returns: - SparseArray
Notes
When value is specified, the result’s
fill_value
depends onself.fill_value
. The goal is to maintain low-memory use.If
self.fill_value
is NA, the result dtype will beSparseDtype(self.dtype, fill_value=value)
. This will preserve amount of memory used before and after filling.When
self.fill_value
is not NA, the result dtype will beself.dtype
. Again, this preserves the amount of memory used.
