## Python: Array Exercise-5 with Solution

Write a Python program to get the current memory address and the length in elements of the buffer used to hold an array’s contents and also find the size of the memory buffer in bytes.

Sample Solution:

Python Code :

``````from array import *
array_num = array('i', [1, 3, 5, 7, 9])
print("Original array: "+str(array_num))
print("Current memory address and the length in elements of the buffer: "+str(array_num.buffer_info()))
print("The size of the memory buffer in bytes: "+str(array_num.buffer_info() * array_num.itemsize))
``````

Sample Output:

```Original array: array('i', [1, 3, 5, 7, 9])
Current memory address and the length in elements of the buffer: (39652
720, 5)
The size of the memory buffer in bytes: 20
```

```>>> a = ('one', 'two', 'three', 'four', 'five')
>>> if 'one' in a:
...     print('The tuple contains one.')
...
The tuple contains one.
>>> b = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> if 2 in b.keys():
...     print('The dict has the key of 2.')
...
The dict has the key of 2.
