أنا لم أفهم الخطأ أين

الأمر وما فيه أن الدالة مكتوبة بهذا الشكل:
else:
while request > 0:
if request >= 100:
request -= 100
print("give 100")
...
result = self.balance - request
return result
في هذه الحالة ستقوم بانقاص result بعد أن يصبح request قيمته صفر بسبب الـ loop التي بالأعلى 
وهذا سيجعل قيمة result لا تتغير.
المفترض أن يكون بهذا الشكل:
else:
result = self.balance - request
while request > 0:
if request >= 100:
request -= 100
print("give 100")
...
return result

ما شاء الله… عمل رائع يا أحمد 
فقط بالنسبة لاسماء المتغيرات والدوال حاول أن تتبع pep8 الذي كتبه صانع لغة بايثون Guido van Rossum:
https://www.python.org/dev/peps/pep-0008/#naming-conventions
مثلاً بدل من printBankName، في بايثون تكتب print_bank_name وهكذا

جميل يا خير الدين، ملاحظ بسيطة لاحظ ان البرنامج لا يعرف balance_badr و balance_essalam لأنك لم تعرفهما.

عمل جميل يا محمود
ملاحظة بسيطة: لاحظ انك لم تحدد البنك الذي تريد سحب الاموال منه.

كيف لم احدد بنك
2 Likes
انت لديك حسابين في بنكين مختلفين البنك الاول و البنك الثاني و ستقوم بسحب الاموال منهما في كل مرة ستسحب من بنك فيجب عليك تحديد البنك الذي تريد سحب الاموال منه مثلا ستسحب 100 من البنك الاول و 200 من البنك الثاني الآن لو تنفذ البرنامج تكون النتيجة هكذا:
give 100
give 100
give 100
سحبنا الأموال لكن قلي 100 الاولى من أي بنك سحبت الاول أم الثاني؟
لكن لو تكون هكذا:
مرحبا بك في: البنك الاول
give 100
مرحبا بك في: البنك الثاني
give 100
give 100
أصبحت الأمور واضحة الآن، أليس كذلك؟

يمكنك اضافة سطر طباعة اسم البنك print(self.bank_name)
