push(item): Stackga yangi ma'lumotni qo'shadi. Bu funksiya o'z ichiga bir ma'lumotni qabul qiladi va uningni stackning oxiriga qo'shadigan.

pop(): Stackning eng ustidagi ma'lumotni o'chiradi va uni qaytaradi. Bu funksiya stackning oxirgi elementini o'chiradi va uni qaytaradi. Agar stack bo'sh bo'lsa, "Stack bo'sh" deb qaytariladi.

top(): Stackning eng ustidagi ma'lumotni qaytaradi, lekin o'chirmaydi. Bu funksiya stackning oxirgi elementini qaytaradi, lekin stackni o'zgarmas qiladi.

size(): Stackdagi elementlar sonini qaytaradi.

empty(): Stack bo'sh bo'lsa True, aks holda False qaytaradi.
