Tuple Methods and Built-in Functions

tuple.count(value)

This method returns the number of times a specified value appears in the tuple.

The grade 'A' appears 3 times.

tuple.index(value, [start, stop])

This method returns the zero-based index of the first occurrence of a specified value.

The first 'banana' is at index 2.

The second 'banana' is at index 4.

'grape' was not found in the tuple.

len()

Returns the number of items in the tuple. This is a constant-time operation.

The tuple has 3 elements.

min(), max(), sum()

These functions are used for aggregation on tuples containing comparable or numeric elements.

Minimum: 5
Maximum: 30
Sum: 85

sorted() and reversed()

• sorted(): Returns a new sorted list from the elements in the tuple.
• reversed(): Returns a reverse iterator. To get a tuple, you must pass it to the tuple() constructor.

Sorted (as list): ['a', 'b', 'c', 'd', 'e']
Reversed (as tuple): ('e', 'b', 'c', 'a', 'd')
Original tuple is unchanged: ('d', 'a', 'c', 'b', 'e')

enumerate()

Returns an iterator that yields pairs of (index, value), which is perfect for loops where you need a counter.
