Python – Tuple Methods
1. What are Tuple Methods?
Tuple methods are built-in functions that help us work with tuple data.
Tuples are read-only, so they have very few methods.
👉 Python tuples have only TWO main methods:
-
count() -
index()
2. count() – Count Items in Tuple
count() tells us how many times a value appears in a tuple.
Example
Output:
Another Example
3. index() – Find Position of Item
index() tells us the index (position) of a value.
Example
Output:
Important Note
-
If the value is not found, Python gives an error.
4. Using index() Safely
Example
5. Tuple with Repeated Values
Example
👉 index() returns the first position only.
6. Tuple Methods with Loop (Real Use)
Example
7. Common Beginner Mistakes
❌ Expecting More Methods Like List
❌ Error: tuple has no append.
❌ Finding Index of Missing Item
✔ Fix:
8. Simple Practice Examples
Example 1: Count Letters
Example 2: Find City Index
Example 3: Student Marks
9. Why Tuples Have Fewer Methods?
✔ Tuples are fixed
✔ Data should not change
✔ Safer than lists
✔ Faster than lists
10. Summary (Tuple Methods)
✔ Tuples have only two methods
✔ count() counts items
✔ index() finds position
✔ Tuples are read-only
✔ Good for fixed data
