Answer
append()extend()
The append() method adds a single item to the end of the list. The single element can be list, number, strings, dictionary etc.The extend() method adds one list at the end of another list.
The syntax of append() method is list.append(item).The syntax of extend() method is list.extend(list1).
For example:
lst1 = [10, 12, 14]
lst1.append(16)
print(lst1)
Output — [10, 12, 14, 16]		For example:
t1 = ['a', 'b', 'c']
t2 = ['d', 'e']
t1.extend(t2)
print(t1)
Output — ['a', 'b', 'c', 'd', 'e']
