To'plam - takrorlanmaydigan va tartiblanmagan ma'lumotlar saqlaydigan ma'lumot turi.

To'plamdan takrorlanmaydigan ma'lumotlarni saqlash uchun foydalaniladi.

toplam = {'pythonuz', 'pythonuz', 1, 2, 1, 1}
print(toplam)
{'pythonuz', 2, 1}


Jingalak qavs yoki set() funksiyasi yordamida to'plamni tuzish mumkin.

literal = {'pythonuz', 'phpuz', 'mqluz'}
print(literal)
{'phpuz', 'pythonuz', 'mqluz'}


Bo'sh bo'lmagan to'plamni set funksiyasi yordamida tuzish tavsiya etilmaydi.
set_funksiyasi = set([1, 2, 3, 4, 'a', 'b'])
print(set_funksiyasi)
{1, 2, 3, 4, 'b', 'a'}

Warning: Function call can be replaced with set literal

Lu'gat va to'plam jingalak qavslar ichida joylashadi. Bo'sh to'plamni lug'atdan farqlash uchun set() funksiyasi yordamida tuzish tavsiya etiladi.
none = set()
print(none)
set()


To'plamda ro'yxat, to'plam yoki lug'at kabi o'zgaruvchan elementlar bo'lishi mumkin emas.
