Exceptions handle karna
try, except, else aur finally ko narrow scope mein use 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.
- Handling Exceptions 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 Handling Exceptions 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
Sirf risky operation ke around specific exception catch karo. else success aur finally cleanup handle karta hai.
ATM invalid PIN, low balance, success aur card return ke separate responses rakhta 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
- try, except, else aur finally ko narrow scope mein use 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.
int(user_input)Risk waala step
Kuch operations runtime par fail ho sakte hain.
Handling Exceptions: working example
Example run karo, phir ek value change karke apni understanding test karo.
finally kab run hota hai?
Code ko complete karo
Invalid text ko fallback zero ke saath safely convert karo.
Key takeaways
- Sirf risky operation ke around specific exception catch karo. else success aur finally cleanup handle karta 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.
