Aapka Pehla Python Program

Aap jo bhi Python program likhoge usme print() ka istemal baar baar hoga — yehi hai jisse aapka code aapse baat karta hai. Chaliye dekhte hain ke yeh asal mein kya karta hai, phir ek real program chalate hain.

print() function

print() jo bhi aap parentheses ke andar likhoge use output ke tor par dikhata hai. Text (jise programming mein "string" kehte hain) quotes ke andar hona chahiye — single (') ya double (") dono chalte hain, bas ek string ke andar consistent rehna hoga.

Comments

# symbol ke baad line mein jo bhi likha ho woh comment hota hai — Python use bilkul ignore kar deta hai. Comments sirf insaano ke parhne ke liye hote hain (including future mein aap khud), yeh samjhane ke liye ke kuch is tarah kyun likha gaya hai.

Khud chala kar dekho

Yeh raha ek chhota program jisme ek comment aur do print() calls hain. Neeche dikhaya gaya output waqai execute kar ke nikala gaya hai — text badal kar khud bhi example ke neeche button se chala kar dekho.

# This is a comment - Python ignores it
print("Hello, World!")
print("Welcome to Python.")

Hello, World!
Welcome to Python.

Ghor karo, har print() call output mein khud ba khud ek nayi line se shuru hota hai — yeh print() ka default behavior hai. Aage aap dekhoge ke isko kaise badalte hain.

Aage: variables — values ko asal mein store aur reuse kaise karein, sirf fixed text print karne ke bajaye.
