Python Tuples
1. What is a Tuple?
A tuple is a collection of items, just like a list.
But there is one big difference 👇
👉 Tuples cannot be changed.
Once a tuple is created, you cannot add, remove, or change items.
2. Creating a Tuple
Tuples are written using round brackets ( ).
Example
3. Tuple with One Item (Important)
To create a tuple with one item, you must add a comma.
Example
❌ Without comma, it becomes a string.
4. Access Tuple Items
Tuples use index numbers, just like lists.
Index starts from 0.
Example
5. Negative Indexing
Example
6. Loop Through a Tuple
Example
7. Check Item Exists
Example
8. Tuple Length
Example
9. Tuple Cannot Be Changed (Very Important)
❌ Wrong Example
❌ Error: tuple does not support item assignment.
10. Change Tuple (Trick Method)
To change a tuple:
-
Convert to list

Example
11. Add Items to Tuple (Trick)
Example
12. Remove Items from Tuple (Trick)
Example
13. Tuple Methods
Tuples have only two methods.
count()
index()
14. Why Use Tuples?
✔ Data should not change
✔ Faster than lists
✔ Protect important data
15. Common Beginner Mistakes
❌ Forgetting Comma in Single Tuple
✔ Correct:
16. Simple Practice Examples
Example 1: Student Details
Example 2: Loop Tuple
Example 3: Check Length
17. Summary (Python Tuples)
✔ Tuples store many items
✔ Tuples cannot be changed
✔ Use index to access items
✔ Only count() and index() methods
✔ Safe for fixed data
