Reja I. Kirish II. Asosiy qism Pythonda kortejlar bilan ishlash

Kortej elementlariga murojat
Kortej elementlariga for va while takrorlash operatorlari orqali murojaat quyidagicha
amalga oshiriladi:
user=("Erkin",30,True)
i=0
print("for sikli yordamida")
for u in user:
print(u)
print("while sikli yordamida")
while i
print(user[i])
i+=1
Kortej elementini mavjudlikka tekshirish
Kortejda biror elementning mavjudligini xuddi ro’yxatlardagi kabi in operatoridan
foydalanib amalga oshiriladi:
user=("Erkin",30,True)
if "Erkin" in user:
print("Foydalanuvchi ismi Erkin")

2.Kortejlarga misollar
Masala. , , , , va
elementlardan iborat bo‘lgan “Talaba” kotreji hosil qilinsin va talabalar ro‘yxati tuzilsin. Hamda, ro‘yxatlar bilan ishlash metodlari va funksiyalaridan foydalanib kotrejlar ustida quyidagi amallar bajarilsin:
➢ Qo‘shish, o‘chirish, tahrirlash va boshqa amallar bajarilsin;
➢ Erkaklar soni eng ko‘p bo‘lgan kurs nomeri;
➢ Eng ko‘p tarqalgan erkak va ayollar ismlari;
➢ Yoshi va ismi bir xil bo‘lgan talaba qizlar familiyalarining alfavit tartibidagi
ro‘yxati;
➢ Ro‘yxat kurslarga ajratilsin.
