Masshtablilik va qayta foydalanish imkoniyati: Django kodni qayta ishlatish va modullikni targ'ib qiladi, bu esa dasturchilarga ularni qayta foydalanish mumkin bo'lgan modullar yoki ilovalarga bo'lish orqali kengaytiriladigan ilovalarni yaratishga imkon beradi.
URL yo'naltirish: Django moslashuvchan URL marshrutlash tizimini taqdim etadi, bu esa ishlab chiquvchilarga ilovaning turli qismlari uchun toza va foydalanuvchilar uchun qulay URL manzillarini aniqlash imkonini beradi.
Template Engine: Django shablon mexanizmi HTML shablonlarini loyihalash va renderlash jarayonini soddalashtiradi, bu esa dinamik veb-sahifalarni yaratishni osonlashtiradi.
Autentifikatsiya va avtorizatsiya: Django foydalanuvchi autentifikatsiyasi va avtorizatsiyasi uchun mustahkam o'rnatilgan vositalarni taklif etadi, bu esa ilovaning turli qismlariga xavfsiz kirishni nazorat qilishni ta'minlaydi.

Djangoni o'rnatish uchun avval djangoning rasmiy saytiga (https://www.djangoproject.com) tashrif buyuring va yuklab olish bo'limini bosish orqali djangoni yuklab oling. Bu erda biz Djangoni yuklab olish uchun turli xil variantlarni ko'ramiz.
Django o'rnatishni boshlash uchun pip talab qiladi. Pip - bu python-da yozilgan paketlarni o'rnatish va boshqarish uchun ishlatiladigan paket menejeri tizimi. Python 3.4 va undan yuqori versiyalari uchun paketlarni boshqarish uchun pip3 ishlatiladi.
