1. Optimize Function Return Values Unpacking: 📦 Resist the urge to unpack excessive return values from functions. Stick to a maximum of three variables for clearer code. Consider using lightweight classes or named tuples for complex returns.

  from collections import namedtuple


  # Define a named tuple for employee details

  Employee = namedtuple('Employee', ['employee_id', 'first_name', 'last_name', 'age', 'department'])


  def fetch_employee_details():

      # Simulate fetching employee details from a database

      employee_id = 101

      first_name = "Emily"

      last_name = "Smith"

      age = 30

      department = "Engineering"

      return Employee(employee_id, first_name, last_name, age, department)


  # Call the function and unpack the named tuple

  employee = fetch_employee_details()


  # Access individual attributes of the named tuple

  print("Employee ID:", employee.employee_id)

  print("First Name:", employee.first_name)

  print("Last Name:", employee.last_name)

  print("Age:", employee.age)

  print("Department:", employee.department)

1. Prioritize Raising Exceptions Over Returning None: ⚠️ Instead of returning None for errors or exceptional cases, raise exceptions for clearer feedback. This facilitates debugging and code maintenance.

  # Raising an exception

  def calculate_ratio(a, b):

      if b == 0:

          raise ValueError("Division by zero is not allowed")

      return a / b


  try:

      result = calculate_ratio(10, 0)

  except ValueError as e:

      print("Error:", e)

1. Enhance Flexibility with Keyword Arguments: 🎯 Empower function callers to specify optional behaviors using named parameters. Utilize keyword arguments and catch-all parameters (**kwargs) for maximum flexibility.

  # Define a function with keyword arguments

  def greet_person(name, salutation="Hello"):

      print(f"{salutation}, {name}!")


  # Call the function with and without specifying optional behavior

  greet_person("Alice") # Output: Hello, Alice!

  greet_person("Bob", salutation="Hey") # Output: Hey, Bob!
