Tracebacks aur error types

Exceptions ko final line se cause tak read karo.

PDF · Chapter 22 · p.44-45
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
  • Tracebacks and Error Types 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 Tracebacks and Error Types 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

Traceback exception tak call path record karta hai. Exception type/message se start karke last relevant frame inspect karo.

Real-world connection

Delivery tracking history failed destination se pehle har stop dikhati hai.

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

  • Exceptions ko final line se cause tak read karo.
  • Mistake useful feedback hai: error ki last line padho, ek cheez change karo aur dobara run karo.

Key takeaways

  • Traceback exception tak call path record karta hai. Exception type/message se start karke last relevant frame inspect karo.
  • Is idea ko seekhne ka fastest way example ko change karke rerun karna hai.
