Append Items

To add an item to the end of the list, use the append() method:

python

thislist = ["apple", "banana", "cherry"]
thislist.append("orange")
print(thislist)

To insert a list item at a specified index, use the insert() method.

The insert() method inserts an item at the specified index:

python

thislist = ["apple", "banana", "cherry"]
thislist.insert(1, "orange")
print(thislist)

Note: Note: As a result of the examples above, the lists will now contain 4 items.

To append elements from another list to the current list, use the extend() method.

python

thislist = ["apple", "banana", "cherry"]
tropical = ["mango", "pineapple", "papaya"]
thislist.extend(tropical)
print(thislist)

The elements will be added to the end of the list.

The extend() method does not have to append lists, you can add any iterable object (tuples, sets, dictionaries etc.).

python

thislist = ["apple", "banana", "cherry"]
  thistuple = ("kiwi", "orange")
thislist.extend(thistuple)
print(thislist)
