Tuples are ordered, immutable collections of items. Once a tuple is created, its elements cannot be changed. Tuples are often used to store related pieces of information and can contain items of different data types.<\/p>\n\n\n\n

Creating Tuples<\/h2>\n\n\n\n

You can create a tuple by placing comma-separated values inside parentheses.<\/p>\n\n\n\n

Tuples can store multiple items in a single variable. They can include different data types such as strings, integers, floats, and even other tuples.<\/p>\n\n\n\n

# Creating a tuple of strings\nfruits = ("apple", "banana", "cherry")\n\n# Creating a tuple of integers\nnumbers = (1, 2, 3, 4, 5)\n\n# Creating a tuple with mixed data types\nmixed_tuple = (1, "Hello", 3.14, True)<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Accessing Tuple Items<\/h2>\n\n\n\n
You can access individual items in a tuple using indexing. Python uses zero-based indexing.<\/p>\n\n\n\n
The index 0<\/code> accesses the first item in the tuple, while the index -1<\/code> accesses the last item.<\/p>\n\n\n\n
# Accessing tuple items\nprint(fruits[0])  # Output: apple\nprint(fruits[-1]) # Output: cherry<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Immutable Nature of Tuples<\/h2>\n\n\n\n
Tuples are immutable, meaning you cannot change their items after creation.<\/p>\n\n\n\n
Attempting to change an item in a tuple will result in an error.<\/p>\n\n\n\n
# Trying to modify a tuple (this will raise an error)\n# fruits[1] = "blueberry"<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Tuple Methods<\/h2>\n\n\n\n
Tuples have built-in methods like count()<\/code> and index()<\/code>.<\/p>\n\n\n\n
    \n
  • count()<\/strong>: Returns the number of times a specified value appears in the tuple.<\/li>\n\n\n\n
  • index()<\/strong>: Returns the index of the first occurrence of a specified value.<\/li>\n<\/ul>\n\n\n\n
    # Tuple methods\ncount_of_apples = fruits.count("apple")\nindex_of_banana = fruits.index("banana")\n\nprint("Count of apples:", count_of_apples)  # Output: 1\nprint("Index of banana:", index_of_banana)  # Output: 1<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Using Tuples for Multiple Assignments<\/h2>\n\n\n\n
    Tuples are commonly used to assign multiple variables at once.<\/p>\n\n\n\n
    You can unpack a tuple into multiple variables.<\/p>\n\n\n\n
    # Multiple assignment with tuples\ncoordinates = (10, 20)\nx, y = coordinates\n\nprint("x:", x)  # Output: 10\nprint("y:", y)  # Output: 20<\/pre><\/div>\n\n\n\n
    <\/p>\n\n\n\n
    Python Tuples Example Code<\/h2>\n\n\n\n
    This program creates a tuple of fruits and demonstrates accessing items, using tuple methods, and multiple assignments.<\/p>\n\n\n\n
    # Creating a tuple\nfruits = ("apple", "banana", "cherry")\n\n# Accessing tuple items\nprint(fruits[0])  # Output: apple\nprint(fruits[-1]) # Output: cherry\n\n# Tuple methods\ncount_of_apples = fruits.count("apple")\nindex_of_banana = fruits.index("banana")\n\nprint("Count of apples:", count_of_apples)  # Output: 1\nprint("Index of banana:", index_of_banana)  # Output: 1\n\n# Multiple assignment with tuples\ncoordinates = (10, 20)\nx, y = coordinates\n\nprint("x:", x)  # Output: 10\nprint("y:", y)  # Output: 20<\/pre><\/div>\n\n\n\n
