if aur else
Do paths mein se exactly ek choose karo.
Idea, words aur real-world use pehle padho.
Example run karo, phir code task solve karo.
Quick check aur apne notes se concept explain karo.
- if and else ko apne words mein explain kar paana.
- Working example ko run aur modify kar paana.
Kisi question ka answer dene se pehle hum samjhenge ki if and else 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
if condition falsy ho toh else fallback path deta hai. Dono mein se ek block execute hota hai.
Payment do-path decision mein approved ya declined hota 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
- Do paths mein se exactly ek choose karo.
- Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.
Concept ko step-by-step dekho
Arrows use karke data ka safar samjho.

Condition hamesha True ya False banti hai.
if and else: working example
Example run karo, phir ek value change karke apni understanding test karo.
else kab run hota hai?
Code ko complete karo
Score 55 ke liye pass return karo.
Key takeaways
- if condition falsy ho toh else fallback path deta hai. Dono mein se ek block execute hota hai.
- Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
Pass the quick check and coding task to complete this lesson.
