Append Row(s) to a NumPy Record Array

Question

Is there a way to append a row to a NumPy rec.array()? For example,

x1=np.array([1,2,3,4])
x2=np.array([\'a\',\'dd\',\'xyz\',\'12\'])
x3=np.array([1.1,2,3,4])
r         


        

Answer 1

np.core.records.fromrecords(r.tolist()+[(5,'cc',43.)])

Still it does split, this time by rows. Maybe better?
