    Study Notes

    Syntax

    • Indentation: Python uses indentation (spaces or tabs) to define block-level structure.
    • Comments: Comments start with # and extend to the end of the line.
    • Print function: print() is a function in Python, unlike in Python 2 where it was a statement.

    Objects

    • Everything is an object: In Python, every value is an object, including numbers, strings, and functions.
    • Attributes and Methods: Objects have attributes (data) and methods (functions).
    • Dynamic typing: Python is dynamically typed, which means the data type of a variable is determined at runtime.

    Inheritance

    • Single Inheritance: A child class inherits from a single parent class.
    • Multiple Inheritance: A child class can inherit from multiple parent classes.
    • Method overriding: A child class can override methods from its parent class.

    Decorators

    • Function wrappers: Decorators are special types of functions that wrap around other functions.
    • Syntax: @decorator_name is used to apply a decorator to a function.
    • Use cases: Decorators are used for logging, authentication, and caching, among other things.

    Data Structures

    • Lists: Ordered collections of items, denoted by [].
    • Tuples: Ordered, immutable collections of items, denoted by ().
    • Dictionaries: Unordered collections of key-value pairs, denoted by {}.
    • Sets: Unordered collections of unique items, denoted by set() or {}.

    Sintaksis

    • Indentatsiya: Python bukilishi (bo'shliqlar yoki belgilar) blok-darajali tuzilmani aniqlash uchun ishlatadi.
    • Izohlar: Izohlar # belgisidan boshlanadi va qatorning oxirigacha davom etadi.
    • Print funktsiyasi: Python 2 dagi bayonotdan farqli o'laroq, print() Python da funktsiyadir.

    Ob'ekt

    • Hamma narsa ob'ekt: Python da har qanday qiymat ob'ekt hisoblanadi, jumladan sonlar, satrlar va funktsiyalar.
    • Atributlar va metamlar: Ob'ektlarda atributlar (ma'lumotlar) va metamlar (funktsiyalar) mavjud.
    • Dinamik turlanish: Python dinamik turlanishga ega, bu esa o'zgaruvchi turi.runtime da aniqlanishini anglatadi.

    Merosxo'rlik

    • Yagona merosxo'rlik: Bolalar klassi yagona ota-ona klassidan merosxo'rlik qiladi.
    • Ko'p merosxo'rlik: Bolalar klassi ko'p ota-ona klassidan merosxo'rlik qilishi mumkin.
    • Metod uzatish: Bolalar klassi ota-ona klassidan metodlarni uzatishi mumkin.

    Dekoratorlar

    • Funktsiya qoplari: Dekoratorlar boshqa funktsiyalarni o'rab oluvchi maxsus funktsiyalardir.
    • Sintaksis: @dekorator_nomi funktsiyaga dekorator uyg'otish uchun ishlatiladi.
    • Foydalanish sohalari: Dekoratorlar loglash, autentifikatsiya va keshlash kabi vazifalarda qo'llaniladi.

    Ma'lumot tuzilmalari

    • Ro'yxatlar: Tartiblangan buyumlar to'plami, [] bilan ifodalanadi.
    • Tupasa: Tartiblangan, o'zgarmas buyumlar to'plami, () bilan ifodalanadi.
    • Lug'atlar: Tartibsiz kalit-qiymat juftliklar to'plami, {} bilan ifodalanadi.
    • To'plamlar: Tartibsiz yagona buyumlar to'plami, set() yoki {} bilan ifodalanadi.
