السلام عليكم ورحمة الله وبركاته
في هذا البرنامج أهدف الى تحويل Binary set الى نوع معين من signal حسب اختيار المستخدم فشكله وطريقة رسمه تختلف من signal الى أخرى.
هذه أول مرة لي على الإطلاق أتعامل فيها مع لغة Python
أمس كانت أول مرة لي ومحتاجة أغير لون white blank إلى نفس لون خلفية الشاشة كنت قد جربت ذلك لكنها تؤثر على output plot
ولا يظهر بعد ذلك.
بحثت كثيرًا ولم اجد حل! أتمنى المُساعدة، محتاجة أسلم الواجب في مادة الشبكات في ظرف قصير ويعطيكم العافية
