# Returns length of linkedlist
print(l_list.length())

output: 7

Deleting Linkedlist elements

# Remove first occurance of an element (3) 
# l_list: 20->10->1->2->3->4->3

l_list.removeElement(3)
l_list.show()

output: 20->10->1->2->4->3

# Remove using element position 
# l_list: 20->10->1->2->4->3

l_list.removeAtLoc(2)
l_list.show()

output: 20->1->2->4->3

# Remove Head/First element in linkedlist 
# l_list: 20->1->2->4->3

l_list.removeHead()
l_list.show()

output: 1->2->4->3

# Remove Tail/Last element in linkedlist 
# l_list: 1->2->4->3

l_list.removeTail()
l_list.show()

output: 1->2->4

# Remove All elements in linkedlist 
# l_list: 1->2->4->3

l_list.removeAll()
l_list.show()

output: None

Checking Linkedlist is Empty/Not

print(l_list.isEmpty())

output: True

Indexing Linkedlist element with location

# Get Linkedlist with location. Linkedlist are zero-indexed based
l_list.add((13, 41, 34))
print(l_list.eleAt(2))

output: 34

Uninstall Package

pip uninstall py-linkedlist
