Python Tutorial #29 - Tuple in Python Programming for Beginners
In this video by Programming for beginners we will see Tuple in Python Programming for Beginners, in Python tutorial for beginners series.
Python programming language is very easy to learn for students and professionals.

A tuple in Python is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas we can change the elements of a list.

Creating a Tuple
A tuple is created by placing all the items (elements) inside parentheses (), separated by commas. The parentheses are optional, however, it is a good practice to use them.
A tuple can have any number of items and they may be of different types (integer, float, list, string, etc.).

Example:
my_tuple = (1, 2, 3)

Create a Python Tuple With one Element:
var1 = ("Hello") # string
var2 = ("Hello",) # tuple

Access Python Tuple Elements:
1. Indexing
2. Negative Indexing
3. Slicing

Python Tuple Methods:
1. count
2. index

Iterating through a Tuple in Python
We can use the for loop to iterate over the elements of a tuple.

Advantages of Tuple over List in Python
- We generally use tuples for heterogeneous (different) data types and lists for homogeneous (similar) data types.
- Since tuples are immutable, iterating through a tuple is faster than with a list. So there is a slight performance boost.
- Tuples that contain immutable elements can be used as a key for a dictionary. With lists, this is not possible.
- If you have data that doesn't change, implementing it as tuple will guarantee that it remains write-protected.
