Assigning complex values to numpy arrays?

Question

This gives the expected result

x = random.rand(1) + random.rand(1)*1j
print x.dtype
print x, x.real, x.imag

and this works

Answer 1

I used astype to change the type to complex and it worked in my case (Python 3), although I am not sure whether it is the best way. One example:

import numpy as np
c2 = np.empty([2,2]).astype(complex)
c2[0] = 5j+2
