  • This is in the [docs](https://docs.python.org/3/library/exceptions.html#NotImplementedError).
  • * abstract methods should raise this exception when they require derived classes to override the method
  • * while the class is being developed to indicate that the real implementation still needs to be added
  • It's a way to have a placeholder method name to "reserve namespace", but with the actual method body "coming soon".

  • * When the implementation is still WIP, but you want to leave a placeholder for the method name and signature
  • It's a way to to "reserve namespace", but with the actual method body "coming soon" (from you or someone else).

It's a way to have a placeholder method name to "reserve namespace", but with the actual method body "coming soon".
