Functions

• • What are Functions?: Functions are blocks of code that perform a specific task. They allow us to break down complex problems into smaller, manageable pieces. We creates Functions to Create reusable code blocks with parameters and return values.
  • Defining Functions:
    Python

    def greet(name):
        return f"Hello, {name}!"
    

    In this example, we define a function called greet that takes a name as an argument and returns a personalized greeting.

  • Calling Functions:
    Python

    print(greet("Alice"))  # Output: Hello, Alice!
