Python | Numpy fromarrays() method

Last Updated : 19 Sep, 2019

With the help of numpy.core.fromarrays() method, we can create the record array by using the list of different arrays by using numpy.core.fromarrays() method.

Syntax : numpy.core.fromarrays([li1, li2....], metadata) Return : Return the record of an array.

Example #1 : In this example we can see that using numpy.core.fromarrays() method, we are able to get the record array by using list of different arrays.

Python3 1=1

# import numpy
import numpy as np

# using numpy.core.fromarrays() method
li1 = np.array([101, 102, 103, 104])
li2 = np.array(['Jitender', 'Purnima', 'Ruhi', 'Varun'])
li3 = np.array([21, 22, 12, 35])

gfg = np.core.records.fromarrays([li1, li2, li3],
                      names ='Rollno, Name, Age')

print(gfg[1])

Output :

(102, 'Purnima', 22)

Example #2 :

Python3 1=1

# import numpy
import numpy as np

# using numpy.core.fromarrays() method
li1 = np.array([101, 102, 103, 104])
li2 = np.array(['Jitender', 'Purnima', 'Ruhi', 'Varun'])
li3 = np.array([21, 22, 12, 35])

gfg = np.core.records.fromarrays([li1, li2, li3],
                      names ='Rollno, Name, Age')

print(gfg.Rollno)
print(gfg.Name)
print(gfg.Age)

Output :

[101 102 103 104] ['Jitender' 'Purnima' 'Ruhi' 'Varun'] [21 22 12 35]
