• 7 Python Code Smells: Olfactory Offenses To Avoid At All Costs | ArjanCodes - Great explanation of various levels of code smells along with live refactoring
  1. Imprecise types -> use enum instead of a generic string
  2. Duplicate code -> create generic / reusable function
  3. Not using available built-in functions -> use list comprehension instead of writing for loop on an array
  4. Vague identifiers -> rename variables with units (e.g. amount becomes hours_worked)
  5. Using isinstance to separate behavior for subtypes -> logic is in wrong place; instead use inheritance to call the subtype’s implementation (e.g. company.pay_employee(company.emp[0]) becomes company.emp[0].pay())
  6. Using boolean flags to make a method do 2 different things -> separate into multiple, smaller scoped functions
  7. Catching and then ignoring exceptions -> either do something or remove try/except
  8. (BONUS): Throwing built-in Errors -> create custom Error class to provide more details back regarding the specific error (like values along with the message)
