Python

How do I get the class Text to call head$()$ in the format of Text.head?

I want to be able to type

Text.head

and have it return the first node in the list, to be precise.

class Text:

def $\_\_$init$\_\_($self$,$ initial$\_$data$=$None$)$:

self.head $=$ None

self.tail $=$ None

self.length $=0$

if initial$\_$data:

if isinstance$($initial$\_$data, str$)$:

for char in initial$\_$data:

self.append$($char$)$

elif isinstance$($initial$\_$data, Text$)$:

current $=$ initial$\_$data.head

while current:

self.append$($current$.$char$)$

current $=$ current.next

else:

raise TypeError$("$Initial data must be a string or Text object"$)$

$$def head$()$:

$$return self.head
