At some point you would have started the definition of the function, you had the parameters ready...

But then you have to call "that method that converts the first letter to upper case".

Was it `upper`? Was it `uppercase`? `first_uppercase`? `capitalize`?

Then, you try with the old programmer's friend, editor autocompletion.

        return supertypeOf(newArrayType(lowerBounds[0]));
      } else {
        Type[] upperBounds = wildcard.getUpperBounds();
        checkArgument(upperBounds.length == 1, "Wildcard should have only one upper bound.");
        return subtypeOf(newArrayType(upperBounds[0]));
      }
    }
    return JavaVersion.CURRENT.newArrayType(componentType);
  }

                    openapi_response = operation_responses.setdefault(
                        status_code_key, {}

        return supertypeOf(newArrayType(lowerBounds[0]));

А теперь представьте, что вы пишете её с нуля.

В какой-то момент вы бы начали определение функции, у вас были бы готовы параметры...

Но затем нужно вызвать «тот метод, который делает первую букву заглавной».

Это был `upper`? Или `uppercase`? `first_uppercase`? `capitalize`?

Тогда вы пробуете старого друга программиста — автозавершение редактора кода.

Then, when you create an instance of that `Settings` class (in this case, in the `settings` object), Pydantic will read the environment variables in a case-insensitive way, so, an upper-case variable `APP_NAME` will still be read for the attribute `app_name`.
