Creation
of Nodes
The
nodes are created by implementing a class which will hold the pointers along
with the data element.
In the below example we create a class named daynames to
hold the name of the weekdays. The nextval pointer is initialized to null and
three nodes and initialized with values as shown.
The
nextval pointer of node e1 points to e3 while the nextval pointer of node e3
points to e2.
class daynames:
def
__init__(self,
dataval=None):
self.dataval
= dataval
self.nextval
= None
e1 =
daynames('Mon')
e2 =
daynames('Wed')
e3 =
daynames('Tue')
e1.nextval
= e3
e3.nextval
= e2
