Python Tuples

---

Tuple

my_tuple = (1, "hello", True)

The main characteristics of a tuple are:

1. Defined by round bracts, and each element in the tuple is separated by a comma
2. Collection fo elements that can be of any data type
3. Iterable object: can be divided in smaller parts
4. Immutable Object: which means that can not be modified
5. Orderd: ammit the repetiton of elements and can be sliced and indexed

Why use tuples?

If an array is not to be changed, it is preferable to use a tuple rather than a list for the following reasons:

• The computation is faster. Processing time for a tuple is less than for a list. > - Memory space is less. Tuples consume less memory space than lists.

The sintax for a one-element tuple is:

• tuple = (x, )

Built-in Functions

Tuples are immutable data structures in Python, and they provide a convenient way to group related data together. Here are the 10 most commonly used tuple functions in Python:

1. len(): Returns the length of a tuple.

t = (1, 2, 3, 4, 5)
print(len(t)) # Output: 5
 

2. tuple(): Creates a new tuple from a sequence or iterable.

s = "hello"
t = tuple(s)
print(t) # Output: ('h', 'e', 'l', 'l', 'o')

3. count(): Returns the number of occurrences of a value in a tuple.

t = (1, 2, 2, 3, 3, 3, 4, 5)
print(t.count(3)) # Output: 3

4. index(): Returns the index of the first occurrence of a value in a tuple.

t = (1, 2, 3, 4, 5)
print(t.index(3)) # Output: 2

5. sorted(): Returns a new sorted list from a tuple.

t = (5, 3, 1, 2, 4)
sorted_t = sorted(t)
print(sorted_t) # Output: [1, 2, 3, 4, 5]

6. max(): Returns the maximum value in a tuple.

t = (1, 2, 3, 4, 5)
print(max(t)) # Output: 5

7. min(): Returns the minimum value in a tuple.

t = (1, 2, 3, 4, 5)
print(min(t)) # Output: 1

8. any(): Returns True if any element in the tuple is True, otherwise False.

t = (False, 0, "", 4)
print(any(t)) # Output: True

9. all(): Returns True if all elements in the tuple are True, otherwise False.

t = (True, 1, "hello")
print(all(t)) # Output: True

10. enumerate(): Returns an iterable of tuples, where each tuple contains the index and value of each element in the original tuple

t = ("apple", "banana", "cherry")
for index, value in enumerate(t):
    print(index, value)
 
# Output:
# 0 apple
# 1 banana
# 2 cherry

Work’s in the same way of lists

Difference:

There is a main difference between lists and tuples, tuples are immutable.

• tuple = (1,2,3,4)
• tuple[0] = 5 -⇒ is impossible, you can’t change an elemet of a tuple
