Custom exceptions raise karna
Meaningful domain errors se invalid states reject 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.
- Raising Custom 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 Raising Custom 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
raise signal karta hai ki contract fulfill nahi ho sakta. Custom exception classes domain failures precise banati hain.
Bank invalid withdrawal ko silently change karne ke bajay specific reason se reject 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
- Meaningful domain errors se invalid states reject 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.
Raising Custom Exceptions: working example
Example run karo, phir ek value change karke apni understanding test karo.
Custom domain exceptions normally kis se inherit karti hain?
Code ko complete karo
Score negative ho toh ValueError raise karo.
Key takeaways
- raise signal karta hai ki contract fulfill nahi ho sakta. Custom exception classes domain failures precise banati hain.
- 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.
