Passing Arguments to Functions

In Python, arguments are values passed to a function when it is called.

• These values are used by the function to perform operations or produce results based on input.

• Arguments provide data to functions so they can execute with specific values instead of hardcoded ones.

An argument is a value provided to a function when it is called, and the function can use this value to carry out its task.

Defining Parameters vs. Passing Arguments:

• Parameters are placeholders defined in the function declaration that accept values.

• Arguments are the actual values passed when calling the function.

Example:

def greet(name):         # 'name' is a parameter
    print(f"Hello, {name}!")

greet("Alice")           # "Alice" is an argument

In the above code:

• name is the parameter (a variable that receives the argument).
• “Alice” is the argument (the actual data passed).

Types of Arguments in Python:

1. Positional Arguments:
   • Arguments are matched to parameters in the order they are given.

def add(a, b):
    return a + b

print(add(5, 3))  # Output: 8

2. Keyword Arguments:
   • Arguments are passed using parameter names.

def student_info(name, age):
    print(f"Name: {name}, Age: {age}")

student_info(age=20, name="John")
