Python tuple Function & Methods

 

Python tuple Function & Methods

In Python, tuples are immutable, meaning their elements cannot be modified once the tuple is created. Consequently, there are only a few built-in methods specific to tuples, as they are more limited compared to mutable types like lists. However, there are some functions and operations that can be performed on tuples. Here are some key functions and methods related to tuples in Python:

Built-in Functions:

len():

Returns the length (number of elements) of a tuple.

my_tuple = (1, 2, 3, 'a', 'b', 'c')

length = len(my_tuple)

print(length) # Output: 6

 

max() and min():

Returns the maximum or minimum element in the tuple.

numbers = (10, 5, 8, 20)

max_value = max(numbers)

min_value = min(numbers)

print(max_value, min_value)

# Output: 20 5

 

sum():

Returns the sum of all elements in a tuple (if all elements are numeric).

numbers = (1, 2, 3, 4, 5)

total = sum(numbers)

print(total)

# Output: 15

 

Tuple Methods:

count():

Returns the number of occurrences of a specified value in the tuple.

my_tuple = (1, 2, 3, 'a', 'b', 'a')

count_a = my_tuple.count('a')

print(count_a)

 # Output: 2

 

index():

Returns the index of the first occurrence of a specified value.

my_tuple = (1, 2, 3, 'a', 'b', 'a')

 index_a = my_tuple.index('a')

 print(index_a)

 # Output: 3

 

Functions That Work with Tuples:

sorted():

Returns a new sorted list from the elements of a tuple.

my_tuple = (3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5)

sorted_list = sorted(my_tuple)

print(sorted_list)

 # Output: [1, 1, 2, 3, 3, 4, 5, 5, 5, 6, 9]

 

tuple():

Converts a sequence (e.g., a list or string) into a tuple.

my_list = [1, 2, 3, 4]

converted_tuple = tuple(my_list)

print(converted_tuple)

 # Output: (1, 2, 3, 4)

These functions and methods provide basic functionality for working with tuples in Python. Remember that, due to their immutability, many list methods, like append() or remove(), are not applicable to tuples. If you need to modify a collection, consider using a list instead.
