Exceptions in Python

• We play dual roles
  • Library Creator: We want our functions/methods etc.. to be used effectively. Here we raise exceptions
  • Library User: We handle exceptions
• LBYL (Look before you leap): We will check for all the preconditions and try to use in the correct way
• EAFP (Easier to Ask forgiveness than permission)
  • Python promotes this approach
  • Handle exceptions
• Python official Docs for Errors & Exceptions Refer Here
• Refer Here for the approach followed in Exception handling
