توی این مورد، `str` پارامتر نوعیه که به `List` (یا `list` توی پایتون 3.9 و بالاتر) پاس داده شده.

///

یعنی: "متغیر `items` یه `list` هست، و هر کدوم از آیتم‌های این لیست یه `str` هستن".

/// tip

اگه از پایتون 3.9 یا بالاتر استفاده می‌کنی، لازم نیست `List` رو از `typing` وارد کنی، می‌تونی همون نوع معمولی `list` رو به جاش استفاده کنی.
