Python Training Program Session 13 (Part 1) || Advanced Built-in Data Types || Tuples смотреть онлайн

Hello Everyone! Today in this video I am going to explain Advanced Built-in Data Types in which we learn about Tuples and its operations.

✻ I really hope you find this video useful.

Tuples :
A tuple is a collection which is ordered and unchangeable.
In Python tuples are written with round brackets ().

Access Tuple Items :
You can access tuple items by referring to the index number, inside square brackets.

Negative Indexing :
Negative indexing means beginning from the end, -1 refers to the last item, -2 refers to the second last item etc.

Range of Indexes :
You can specify a range of indexes by specifying where to start and where to end the range.
When specifying a range, the return value will be a new tuple with the specified items.
Remember that the first item has index 0.

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.

Tuple Length :
To determine how many items a tuple has, use the len() method.

Add Items :
Once a tuple is created, you cannot add items to it. Tuples are unchangeable. But we discussed in the video about the methods to add items.

Create Tuple With One Item :
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.

Remove Items :
You cannot remove items in a tuple.
Tuples are unchangeable, so you cannot remove items from it, but you can delete the tuple completely.

Join Two Tuples :
To join two or more tuples you can use the + operator.

The tuple() Constructor :
It is also possible to use the tuple() constructor to make a tuple.

Converting Between Lists and Tuples :
You can use the built-in list() function to convert a tuple to a list, and the built-in tuple() function to convert a list to a tuple.
