Example of function

• def greet(name):

    print(f"Hello, {name}!")

  Here, greet is a function that takes one argument, name. You can call this function with different values:

  greet("Alice")

  greet("Bob")

  The function will output "Hello, Alice!" and "Hello, Bob!" when called. Functions can also return values using the return statement:

  def add_numbers(a, b):

    return a + b

  Calling add_numbers(3, 5) will return 8. Functions can take multiple parameters and even default arguments:

  def greet(name, message="Welcome!"):

    print(f"Hello, {name}! {message}")

  In this case, the message parameter has a default value of "Welcome!", so calling greet("John") will use that default message unless you specify another message, like greet("John", "Good to see you!").

  You can also use lambda functions, which are small, anonymous functions defined using the lambda keyword. For example:

  square = lambda x: x * 2

  print(square(4))

  This lambda function takes one argument x and returns its square, outputting 8 when called. Combining control flow and functions allows you to write efficient and reusable Python code.
