tuple

There are 4 collection data types in py:

Lists: Is a collection which is ordered and changeable. Allows duplicate members

Tuple: is a collection which is ordered and unchangeable. Allows duplicate members

Set: is a collection which is unordered and unindexed. No duplicate members

Dictionary :is a collection which is unordered, changeable and indexed. No duplicate members.

To create a tuple with only one item, you have to add a comma after the item, otherwise Python will not recognize it as a tuple.

Possible values

type() == <class ‘tuple’>

output: (‘orange’, ‘kiwi’, ‘melon’)

Change Tuple Values. Once a tuple is created, you cannot change its values. Tuples are unchangeable, or immutable as it also is called.

But there is a workaround. You can convert the tuple into a list, change the list, and convert the list back into a tuple.

output: (“apple”, “kiwi”, “cherry”) changes: banana changed to kiwi

1st way to add new items: Convert into a list

2nd way to add new items: Add tuple to a tuple

To delete items we can use append() method, but after converting tuple to list.

Also we can delete the tuple completely
