-________________
+----------------
 
 The literal_eval method safely parses and evaluates an expression for a Python datatype.
 Supported data types are: strings, numbers, tuples, lists, dicts, booleans and None.

+XML (nested data)
+=================
+
+XML parsing in Python is possible using the `xml` package.
+
+Example:
+
+.. code-block:: python
+
+        # reading XML content from a file
+        import xml.etree.ElementTree as ET
+        tree = ET.parse('country_data.xml')
+        root = tree.getroot()
+
+More documentation on using the `xml.dom` and `xml.sax` packages can be found
+`here <https://docs.python.org/3/library/xml.html>`__.

+Numpy Array (flat data)
+=======================

-Pickle
-******
+Python's Numpy array can be used to serialize and deserialize data to and from byte representation.
+
+Example:
+
+.. code-block:: python
+
+    import numpy as np
+
+    # Converting Numpy array to byte format
+    byte_output = np.array([ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]).tobytes()
+
+    # Converting byte format back to Numpy array
+    array_format = np.frombuffer(byte_output)

+Pickle (nested data)

 The native data serialization module for Python is called `Pickle
 <https://docs.python.org/2/library/pickle.html>`_.
