or any other case variation (uppercase, first letter in uppercase, etc), your function will see the parameter `short` with a `bool` value of `True`. Otherwise as `False`.

Bir noktada fonksiyonun tanımına başlayacaktınız, parametreleri hazır hale getirdiniz...

Ama sonra "ilk harfi büyük harfe dönüştüren yöntemi" çağırmanız gerekir.

 `upper` mıydı ? Yoksa  `uppercase`' mi? `first_uppercase`? `capitalize`?

Ardından, programcıların en iyi arkadaşı olan otomatik tamamlama ile denediniz.
