Methods aur properties

Objects ko behavior aur validated attributes do.

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
  • Methods and Properties 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 Methods and Properties 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

Instance methods self par act karte hain. Properties attribute syntax ke through validation expose karti hain.

Real-world connection

Bank account balance aur usse change karne ke rules dono own karta hai.

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

  • Objects ko behavior aur validated attributes do.
  • Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Concept ko step-by-step dekho

Naksha

Class data aur behavior ka naksha hoti hai.

Runnable example

Methods and Properties: working example

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

Key takeaways

  • Instance methods self par act karte hain. Properties attribute syntax ke through validation expose karti hain.
  • Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
