compare_chararrays(a1, a2, cmp, rstrip)

Parameters

a1, a2 : array_like

Arrays to be compared.

cmp : {"<", "<=", "==", ">=", ">", "!="}

Type of comparison.

rstrip : Boolean

If True, the spaces at the end of Strings are removed before the comparison.

Raises

ValueError

If :None:None:`cmp_op` is not valid.

TypeError

If at least one of a or :None:None:`b` is a non-string array

Returns

out : ndarray

The output array of type Boolean with the same shape as a and b.

Performs element-wise comparison of two string arrays using the comparison operator specified by :None:None:`cmp_op`.

Examples

>>> a = np.array(["a", "b", "cde"])
... b = np.array(["a", "a", "dec"])
... np.compare_chararrays(a, b, ">", True)
array([False,  True, False])

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
