Parameters and Arguments

Parameters are variables defined in the function declaration, and arguments are the actual values passed to the function when it is called.

Example:

def greet_user(name):
    print(f"Hello, {name}!")

greet_user("Carlos")  # 'Carlos' is an argument

Types of Arguments:

• Positional: Assigned by order.
• Keyword: Specified by the parameter name.
• Default: Defined with a default value.
• Variable-length: Use args for tuples and *kwargs for dictionaries.

def show_info(name, age=18):
    print(f"Name: {name}, Age: {age}")

show_info("Ana")       # Uses default value for age
show_info("Luis", 25)
