Type conversion aur validation
Input deliberately convert karo aur invalid values cleanly 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.
- Type Conversion and Validation 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 Type Conversion and Validation 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
int(), float(), str(), list() aur tuple() valid conversion par nayi typed value banate hain. Invalid conversion exception deta hai.
Conversion ticket counter jaisa hai - input destination format ke layak hona chahiye.
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
- Input deliberately convert karo aur invalid values cleanly 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.
name = ?Khali label
Variable ko naam waale label ki tarah socho.
Type Conversion and Validation: working example
Example run karo, phir ek value change karke apni understanding test karo.
int("hello") kya raise karta hai?
Code ko complete karo
Text 125 ko integer mein convert karo.
Key takeaways
- int(), float(), str(), list() aur tuple() valid conversion par nayi typed value banate hain. Invalid conversion exception deta 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.
