Function Returns Multiple Values in Python In Python, functions can return multiple values by separating them with commas. These values are returned as a tuple, but they can be unpacked into individual variables. Basic Syntax python def function_name(): return value1, value2, value3 # Calling and unpacking var1, var2, var3 = function_name() Simple Examples Example 1:…

Variable Length Keyword Arguments in Python Variable length keyword arguments allow a function to accept any number of keyword arguments. This is done using the **kwargs syntax. Syntax python def function_name(**kwargs): # function body # kwargs becomes a dictionary containing all keyword arguments Simple Examples Example 1: Basic **kwargs python def print_info(**kwargs): print(“Information received:”, kwargs) print(“Type of…

Variable Length Positional Arguments in Python Variable length positional arguments allow a function to accept any number of positional arguments. This is done using the *args syntax. Syntax python def function_name(*args): # function body # args becomes a tuple containing all positional arguments Simple Examples Example 1: Basic *args python def print_numbers(*args): print(“Numbers received:”, args) print(“Type of…

Keyword-Only Arguments in Python Keyword-only arguments are function parameters that must be passed using their keyword names. They cannot be passed as positional arguments. Syntax Use the * symbol in the function definition to indicate that all parameters after it are keyword-only: python def function_name(param1, param2, *, keyword_only1, keyword_only2): # function body Simple Examples Example 1: Basic Keyword-Only Arguments…

Positional-Only Arguments in Python Positional-only arguments are function parameters that must be passed by position (order) and cannot be passed by keyword name. Syntax Use the / symbol in the function definition to indicate that all parameters before it are positional-only: python def function_name(param1, param2, /, param3, param4): # function body Simple Examples Example 1: Basic Positional-Only Arguments python def calculate_area(length,…

Default Arguments in Python Functions Default arguments allow you to specify default values for function parameters. If a value isn’t provided for that parameter when the function is called, Python uses the default value instead. Basic Syntax python def function_name(parameter=default_value): # function body Simple Examples Example 1: Basic Default Argument python def greet(name=”Guest”): print(f”Hello, {name}!”)…

1. Positional Arguments How they work: The arguments you pass are matched to the function’s parameters based solely on their order (i.e., their position). The first argument is assigned to the first parameter, the second to the second, and so on. Example: python def describe_pet(animal_type, pet_name): “””Display information about a pet.””” print(f”\nI have a {animal_type}.”) print(f”My {animal_type}’s name…

A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing. Defining a Function In Python, a function is defined using the def keyword, followed by the function name, a set of parentheses (),…

Python Dictionaries: Explanation with Examples A dictionary in Python is an unordered collection of items that stores data in key-value pairs. Dictionaries are: Creating a Dictionary python # Empty dictionary my_dict = {} # Dictionary with initial values student = { “name”: “John Doe”, “age”: 21, “courses”: [“Math”, “Physics”, “Chemistry”], “GPA”: 3.7 } Accessing Dictionary Elements…
