Signature de la méthode astype

def astype(self, dtype, copy=True) 

Description

astype.__doc__

Create an Index with values cast to dtypes.

The class of a new Index is determined by dtype. When conversion is
impossible, a TypeError exception is raised.

Parameters
----------
dtype : numpy dtype or pandas type
    Note that any signed integer `dtype` is treated as ``'int64'``,
    and any unsigned integer `dtype` is treated as ``'uint64'``,
    regardless of the size.
copy : bool, default True
    By default, astype always returns a newly allocated object.
    If copy is set to False and internal requirements on dtype are
    satisfied, the original data is used to create a new Index
    or the original Index is returned.

Returns
-------
Index
    Index with values cast to specified dtype.
