Sir, First of all, thanks for the awesome explanation and code, you did a great job here.
I just wanted to draw your attention to a small issue, that insertion at the beginning will fail if there is no element in the list(i.e. self.head is None)
I added this and it is working fine:
## insertion at the beginning
def insert_at_beginning(self,data):
n=Node(data)
if self.head is None:
self.head = n

else:
temp=self.head
temp.previous=n
n.next=temp
self.head=n
