Lambda aur functional tools
Small functions ko sorted, map, filter aur reduce ke saath 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.
- Lambda and Functional Tools 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 Lambda and Functional Tools 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
Lambda single-expression function hai. Simple transform/filter ke liye readable ho toh comprehension prefer karo.
Lambda temporary label hai jo ek small sorting ya conversion job ke liye 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
- Small functions ko sorted, map, filter aur reduce ke saath 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.
def greet(name):Define karo
Function reusable steps ko ek jagah rakhta hai.
Lambda and Functional Tools: working example
Example run karo, phir ek value change karke apni understanding test karo.
Lambda mein kitne expressions hote hain?
Code ko complete karo
map aur lambda se sab values double karo.
Key takeaways
- Lambda single-expression function hai. Simple transform/filter ke liye readable ho toh comprehension prefer karo.
- 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.
