pandas 1.4.2

ParametersReturns
astype(self, dtype, copy: 'bool' = True)

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.

Create an Index with values cast to dtypes.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
