pandas.DataFrame.infer_objects¶

DataFrame.infer_objects(self: ~FrameOrSeries) → ~FrameOrSeries[source]¶

Attempt to infer better dtypes for object columns.

Attempts soft conversion of object-dtyped columns, leaving non-object and unconvertible columns unchanged. The inference rules are the same as during normal Series/DataFrame construction.

New in version 0.21.0.

Returns

convertedsame type as input object

3  3

>>> df.dtypes
A    object
dtype: object

>>> df.infer_objects().dtypes
A    int64
dtype: object
