`numpy.lib.scimath:power`

Signature

def power(x, p)

Return x to the power p, (x**p).

If x contains negative values, the output is converted to the complex domain.

x : array_like: The input value(s).
p : array_like of ints: The power(s) to which x is raised. If x contains multiple values, p has to either be a scalar, or contain the same number of values as x. In the latter case, the result is x[0]**p[0], x[1]**p[1], ....

out : ndarray or scalar: The result of x**p. If x and p are scalars, so is out, otherwise an array is returned.
