import numpy as np
a1=np.array([1,2,3,4])
a2=np.array(['Red','Green','White','Orange'])
a3=np.array([12.20,15,20,40])
result= np.core.records.fromarrays([a1, a2, a3],names='a,b,c')
print(result[0])
print(result[1])
print(result[2])

 

Sample Output:
(1, 'Red', 12.2)                                                       
(2, 'Green', 15.0)                                                     
(3, 'White', 20.0)
