#Python - Add List Items

#Append Items

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

Example Using the append() method to append an item:

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

---

#Insert Items

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

Example Insert an item as the second position:

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

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

---

#Extend List

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

Example Add the elements of tropical to thislist:

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

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

---

#Add Any Iterable

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

Example Add elements of a tuple to a list:

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