A Python tuple is an immutable sequence type, meaning that once it is created, it cannot be modified. Here's a basic example to illustrate how to create and use tuples in Python:
my_tuple = (1, 2, 3, "apple", "banana")
# Accessing elements in a tuple
first_element = my_tuple[0] # 1
second_element = my tuple[1] # 2
sub_tuple = my_tuple[1:3] # (2, 3)
nested_tuple = (1, 2, (3, 4, 5))
# Looping through a tuple
# Trying to modify a tuple (this will raise an error)
# my_tuple[0] = 10 # TypeError: 'tuple' object does not support item assignment
Here's what happens in each part of the example:
**Creating a tuple**: `my_tuple` is created with mixed data types.
**Accessing elements**: Individual elements are accessed using their index.
**Slicing a tuple**: A portion of the tuple is accessed using slicing.
**Nested tuples**: Tuples can contain other tuples as elements.
**Unpacking a tuple**: Elements of the tuple are assigned to individual variables.
**Looping through a tuple**: Each element in the tuple is printed using a for loop.
**Immutability**: Attempting to change an element of the tuple results in a `Type Error` because tuples are immutable.
