Function

   In Python, a function is a block of code that performs a specific task and can be reused 
   multiple times throughout your program. Functions help in modularizing code, making it more 
   organized, readable,and maintainable. To define a function in Python, 
   you use the def keyword, followed by function name  and its parameters (if any).
   Here's the basic syntax of a Python function:
    def function_name(parameter1, parameter2, ...):
    # Function body (code block)
    # Statements and computations go here
    # You may use the parameters inside the function
    # Optional: Return a value using the 'return' statement
    return result

 

def say_hello():
    return "Hello, World!"
message = say_hello()
print(message)  # Output: Hello, World!

 

 

     OUTPUT



  

  A simple function that adds two numbers and returns the result:

 

def add_numbers(a, b):
    return a + b
result = add_numbers(5, 3)
print(result)  # Output: 8
