Linked list (Python)

Question

I am stuck in this code.
How to print the input songs to screen in this linked list?

class Track:
def __init__(self, title, next):
self.title = title
self.next = next

class Player:
def __init__(self):
self.head = None

def add(self, title):
if not self.head:
self.head = Track(title, None)
return
curr = self.head
while curr.next:
curr = curr.next
curr.next = Track(title, None)

p = Player()
while True:
x = input()
if x == 'end':
break
p.add(x)

#your code goes here

Answer 1

class Track:
def __init__(self, title, next):
self.title = title
self.next = next

class Player:
def __init__(self):
self.head = None

def add(self, title):
if not self.head:
self.head = Track(title, None)
return
curr = self.head
while curr.next:
curr = curr.next
curr.next = Track(title, None)

p = Player()
while True:
x = input()
if x == 'end':
break
p.add(x)

n = p.head
while n != None:
print(n.title)
n = n.next

Answer 2

class Track:
def __init__(self, title, next):
self.title = title
self.next = next

class Player:
def __init__(self):
self.head = None

def add(self, title):
if not self.head:
self.head = Track(title, None)
return
curr = self.head
while curr.next:
curr = curr.next
curr.next = Track(title, None)

p = Player()
while True:
x = input()
if x == 'end':
break
p.add(x)
print(x)

Answer 3

Does printing p not return your inputs?
