4. Get the Length in Bytes of One Array Item

Write a Python program to get the length in bytes of one array item in the internal representation.

Sample Solution:

Python Code :

from array import *
array_num = array('i', [1, 3, 5, 7, 9])
print("Original array: "+str(array_num))
print("Length in bytes of one array item: "+str(array_num.itemsize))

Sample Output:

Original array: array('i', [1, 3, 5, 7, 9])                            
Length in bytes of one array item: 4

• Write a Python program to create an array of floats and display the byte length of each element using itemsize.
• Write a Python program to compare the itemsize of an array of signed integers versus an array of unsigned integers.
• Write a Python program to calculate the total size of an array's buffer by multiplying its length with the itemsize, then verify the itemsize manually.
