maxframe.liteframe.LiteFrame.astype#

LiteFrame.astype(dtype, errors='raise')#

Cast a LiteFrame to a specified dtype.

Parameters:

dtype (data type, or dict of column name -> data type) – Use a numpy.dtype or Python type to cast entire LiteFrame to the same type. Alternatively, use {col: dtype, …}, where col is a column label and dtype is a numpy.dtype or Python type to cast one or more of the DataFrame’s columns to column-specific types.
errors ({'raise', 'coerce'}, default 'raise') –
Control raising of exceptions on invalid data for provided dtype.
- raise : allow exceptions to be raised
- coerce : uncastable values become null and the output dtype changes to the target type.
'ignore' is not supported by LiteFrame astype; use 'coerce' for null-on-failure semantics.

Returns:

Casted LiteFrame.

Return type:

LiteFrame
