astype(self, dtype, copy: 'bool' = True, how=<no_default>)
The class of a new Index is determined by dtype. When conversion is impossible, a TypeError exception is raised.
Note that any signed integer dtype
is treated as 'int64'
, and any unsigned integer dtype
is treated as 'uint64'
, regardless of the size.
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.
Index with values cast to specified dtype.
Create an Index with values cast to dtypes.
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
