bach.DataFrame.astype
astype
(dtype)Cast all or some of the data columns to a certain dtype.
Only data columns can be cast, index columns cannot be cast.
This does not modify the current DataFrame, instead it returns a new DataFrame.
Parameters
dtype (Union[str, Dict[str, str]]) – either:
- A single str, in which case all data columns are cast to this dtype.
- A dictionary mapping column labels to dtype.
Returns
New DataFrame with the specified column(s) cast to the specified dtype
