Numbers aur precision

Integers, floats, complex numbers aur number bases use karo.

PDF · Chapter 7.1, 7.2, 7.10 · p.12-13-14
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
  • Numbers and Precision 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 Numbers and Precision 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

Python integers arbitrary precision rakhte hain. Floats finite binary representation use karte hain, isliye 0.1 exact nahi hota.

Real-world connection

Float ruler se measurement jaisa hai - useful hai par markings limited 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

  • Integers, floats, complex numbers aur number bases use karo.
  • Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Key takeaways

  • Python integers arbitrary precision rakhte hain. Floats finite binary representation use karte hain, isliye 0.1 exact nahi hota.
  • Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
