For loops

Iterable ke har item ko visit karo.

PDF · Chapter 12.1 · p.32-33

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

For Loops 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 For Loops 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

for loop iterable se ek-ek value leta hai. Loop variable har value se rebind hota hai.

Real-world connection

Attendance class list ke har student ko ek baar check karta hai.

Example ko step-by-step padho

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

Kya yaad rakhna hai

Iterable ke har item ko visit karo.
Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Interactive concept lab

Concept ko step-by-step dekho

Arrows use karke data ka safar samjho.

Collection

Loop un items se shuru hota hai jinhe visit karna hai.

Runnable example

For Loops: working example

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

Key takeaways

for loop iterable se ek-ek value leta hai. Loop variable har value se rebind hota hai.
Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
