תרגילים נוספים: שבוע 3

כתבתי ולא קיבלתי כלום חוץ ממסך שחור

יש שם משו שצריך לחפש באינטרנט והוא לא בחומר שנלמד.

זה קשור לאיזה סוג כתיבה עושים לקובץ

היי בנוגע למחברת 1 תרגיל 2 - לא כלכך הבנתי איך המשתמש מכניס קלט של שיר שמופרד בשורות?
למשל כמו הדוגמא שהבאתם:
עבור הקלט: “לילה לילה
מכה אפורה
האוטו שלנו” ואז “line”, יודפס: למה

את צודקת בתרגיל הזה, תניחי שלא המשתמש מכניס את הקלט

לי זה נראה ככה לפני שעשיתי bytearray() על secret

אפשר עזרה ממישהו בתרגיל 1 מחברת 3 (עם התמונה) ?
(:

בטח אשמח לעזור (: (20)
