Logical operators

and, or, not aur short-circuiting se conditions combine karo.

PDF · Chapter 10.3 · p.25
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
  • Logical Operators 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 Logical Operators 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

and ko dono conditions truthy chahiye; or ko ek; not truthiness reverse karta hai. Result pata lagte hi evaluation stop hota hai.

Real-world connection

Cinema entry ke liye age aur payment dono check ho sakte hain - ye and condition 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

  • and, or, not aur short-circuiting se conditions combine karo.
  • Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Key takeaways

  • and ko dono conditions truthy chahiye; or ko ek; not truthiness reverse karta hai. Result pata lagte hi evaluation stop hota hai.
  • Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
