في الواقع يا أمينة المشكلة ليست في while وإنما هي في هذا السطر:
return mony-request
لما؟
لأن هذا السطر يتم تنفيذه بغض النظر عن الشرط في الدالة بمعنى هو مثل:
def withdraw(mony , request):
...
return mony-request
أي أنه لا يوجد أي شرط لإرجاع الناتج, سيتم دائماً تنفيذ هذا السطر بأي حال
ربما إذا اضفتي على السطر شرط بسيط مثل if mony <= request داخلها الحلقة ثم يرجع الفارق بينهم mony-request,
أما else يقوم بارجاع المبلغ كما هو return mony
انتظر تعديلاتك 
balance = 500
def withdraw(balance, request):
print(balance)
if request > balance:
print("Can't give you all this money !!")
elif request < 0:
print("More than zero plz!")
else:
balance = balance - request
while request > 0:
if request >= 100:
request -= 100
print("give 100")
elif request >= 50:

request = 0
return balance

تجنب النسخ واللصق

عمل ممتاز يا احمد… من الافضل ان تقوم بتعريف المتغير balance قبل تعريفه مباشرة بدلا من تعريفه في بداية البرنامج
شغل مضبوط يا علي 
def withdraw( balance, request ):
print( "the value of balance is : ", balance)
if request > balance :
print( "sorry we do not have enough money for your request" )
elif request < 0 :
print( "more than o, please")
elif request < balance :
while request > 0 :
if request >= 100 :
request -=100
print("give 100")
elif request >=50 :
request -=50
print( "give 50" )
elif request >= 10 :
request -=10
print( "give 10" )
elif request >= 5 :
request -=5
print( "give 5" )
elif request < 5 :
print( "give" + str(request))
request = 0
else :
print( "we can not provide this service" )
return balance - request
balance = 500
balance = withdraw( balance, 275 )
balance = withdraw( balance, 30 )
balance = withdraw( balance, 5 )
balance = withdraw( balance, 500 )
balance = withdraw( balance, -1 )
عمل رائع يا منى
لكن هل جربتي ملاحظة قيمة المتغير balance في حال تشغيل السطر:
balance = withdraw( balance, 700)
جربي السطر وأخبريني بالنتيجة
هذا ا تم طباعته قبل التنقيح
the value of balance is : 500
sorry we do not have enough money for your request
-200
لكن بعد تنقيح البرمجيات بهذه الطريقة
def withdraw( balance, request ):
result = balance
print( "the value of balance is : ", balance)
if request > balance :
print( "sorry we do not have enough money for your request" )
elif request < 0 :
print( "more than o, please")
elif request < balance :
while request > 0 :
if request >= 100 :
request -=100
print("give 100")
elif request >=50 :
request -=50
print( "give 50" )
elif request >= 10 :
request -=10
print( "give 10" )
elif request >= 5 :
request -=5
print( "give 5" )
elif request < 5 :
print( "give" + str(request))
request = 0
result = balance - request
else :
print( "we can not provide this service" )
return result
balance = 500
balance = withdraw( balance, 700 )
print (balance)
كانت النتيجة كالتالي
the value of balance is : 500
sorry we do not have enough money for your request
500
وفي حالة الطلب اقل من الرصيد ونقل تعريف الناتج الى ما قبل الحلقة كانت الطباعة كالتالي
the value of balance is : 500
give 100
400
مضبوط جداً… هذا هو المطلوب بالضبط 
انتقلي على المهمة التالية
This is my trying:
def withdraw(balance, request):
r = request
if request > balance:
print("Can't give you all this money !!")
return balance
elif request < 0:
print("More than zero plz!")
return balance
else:
newBalance = balance-request
print("[*] Request for {}$".format(r))
while request > 0:
if request >100:
# remainder = request%100
request-=100
print("give 100")
elif request <100 and request >50:
request-=50
print("give 50")
elif request <50 and request >10:
request-=10
print("give 10")
elif request <10 and request >5:
request-=5
print("give 5")
else:
print("give {}".format(request))
print("[*] Request for {}$ Done".format(r))
print("")
break
return newBalance
balance = 500
balance = withdraw(balance, 277)
balance = withdraw(balance, 30)
balance = withdraw(balance, 5)
balance = withdraw(balance, 500)
and the result was like this
[*] Request for 277$
give 100
give 100
give 50
give 10
give 10
give 5
give 2
[*] Request for 277$ Done
[*] Request for 30$
give 10
give 10
give 10
[*] Request for 30$ Done
[*] Request for 5$
give 5
[*] Request for 5$ Done
Can't give you all this money !!
عمل ممتاز كالعادة يا كمال 
هل نحتاج الجزء request <100 في الشرط:
elif request <100 and request >50:
نفس الأمر مع بقية الشروط الذي تبدأ بـ elif
اها لقد فهمت قصدك استاذ ياسر ^^
شكرا لتنبيهي
تم التصحيح ^^
def withdraw(balance, request):

صار الان ممتاز 
توجد لدي مشكلة عندما ادخل الطلب في الثلاث مرات لا ينقص من الرصيد مع انو طرحت الطلب من الرصيد في ارجاع الدالة
def withdraw(balance, request):
if request < balance:
while request>0:
if request>=100:
request = request- 100
print("give 100")
elif request >= 50:

print("give 50")
elif request >= 10:
request = request-10
print("give 10")
elif request >=5:
request = request- 5
print("give 5")
elif request >=2 :
request = request-2
print("give 2")
else:
print("no found ")
return balance - request
balance = 500
request= input("your request:")
request=int(request)
balance = withdraw(balance, request)
request= input("your request:")
request=int(request)
balance = withdraw(balance, request)
request= input("your request:")
request=int(request)
balance = withdraw(balance, request)
balance = 500
def withdraw(balance, request):
print('balance =',balance)
if request > balance:
print("Can't give you all this money !!")
elif request < 0:
print("More than zero plz!")
else:
balance = balance - request
while request > 0:
if request >= 100:
request -= 100
print("give 100")
elif request >= 50:
request -= 50
print("give 50")
elif request >= 10:
request -= 10
print("give 10")
elif request >= 5:

print("give 5")

request -= request
return balance
balance = withdraw(balance, 277)
balance = withdraw(balance, 30)
balance = withdraw(balance, 5)
balance = withdraw(balance, 500)عمل جميل جدا.
عمل رائع يا خير الدين، لكن ماذا لو تضع الكود احسن من الصورة حتى يتسنى لنا فحص الكود جيدا و تجريبه.
