حسنًا، بالنسبة للاختبار القادم، سأجعل هذا الأمر أكثر أهمية

So for the next quiz, I'm going to make this a little more interesting

.وأفترض أنني أنتقي أصدقائي بشدة

and assume I'm not quite so picky about who my friends are.

سأكون صديقًا للأشخاص الذين تبدأ أسماؤهم بالحرف

I'm going to be friends with people whose name starts with either "D"

."D" أو الحرف "N"

or the letter "N".

والآن إليكم السؤال: نحن ما زلنا بصدد تعريف الإجراء، is_friend

So now the question is: we're still going to define the procedure, is_friend

،ولكنني قمت بتغيير تعريفي للصديق

but I've changed my definition of a friend,

حسنًا سأفترض الآن أني صديق لكل من يبدأ اسمه

so now we assume that I'm friends with everyone whose name starts with

.إما بالحرف "D" وإما بالحرف "N"، وليس أحدًا آخر

either the letter "D' or the letter "N", but no one else.

.لذلك فإن هذه النتيجة لا تزال صحيحة - وهذا سيكون صحيحًا

So this result would still be correct--that would be correct.

،"فإذا سألنا: is_friend هو اسم يبدأ بالحرف "N

If we asked: is_friend a name that starts with the letter "N,"

،"لنقل مثلاً "Ned

let's say "Ned,"

"والآن يجب أن نحصل على النتيجة، "صواب

then we should also get the result, True

.والآن لنرَ ما إذا كان يمكنكم معرفة كيفية تعريف "is_friend" بالنسبة للتعريف الجديد

So see if you can figure out how to define "is_friend" for this new definition.
