Classes aur objects

State aur behavior bundle karne wale new types define karo.

Project-ready extension
1 · Samjho

Idea, words aur real-world use pehle padho.

2 · Karke dekho

Example run karo, phir code task solve karo.

3 · Samjhaao

Quick check aur apne notes se concept explain karo.

Is lesson ke baad
  • Classes and Objects ko apne words mein explain kar paana.
  • Working example ko run aur modify kar paana.
Yahin se start karo - pehle se kuch aana zaroori nahi

Kisi question ka answer dene se pehle hum samjhenge ki Classes and Objects ka matlab kya hai, ye kahan useful hai aur example kaise behave karta hai. Naye words aate hi explain kiye gaye hain.

Idea ko samjho

Class instances ka shared behavior define karta hai. Har object ki own identity aur instance attributes hote hain.

Real-world connection

Class house plan hai; objects us plan se bane separate houses hain.

Example ko step-by-step padho

  1. 1Program mein banaye gaye names aur values pehchaano.
  2. 2Har line ko top-to-bottom trace karo aur dekho wo kya change karti hai.
  3. 3Run Python dabane se pehle output predict karo, phir ek value change karo.

Kya yaad rakhna hai

  • State aur behavior bundle karne wale new types define karo.
  • Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Naksha

Class data aur behavior ka naksha hoti hai.

Runnable example

Classes and Objects: working example

Example run karo, phir ek value change karke apni understanding test karo.

Key takeaways

  • Class instances ka shared behavior define karta hai. Har object ki own identity aur instance attributes hote hain.
  • Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
