Sample Solution:

Python Code :

from array import *
array_num = array('i', [1, 3, 5, 7, 9])
print("Original array: "+str(array_num))
print("Insert new value 4 before 3:")
array_num.insert(1, 4)
print("New array: "+str(array_num))

Sample Output:

Original array: array('i', [1, 3, 5, 7, 9])                            
Insert new value 4 before 3:                                           
New array: array('i', [1, 4, 3, 5, 7, 9])
