Python Input and Output in Hindi – input() aur print() Function Complete Guide for Beginners
Handwritten notes explaining Python Input and Output with print() and input() examples.Agar aap Python programming ki shuruaat kar rahe hain, to Input aur Output sabse pehle seekhne wale concepts me se ek hain. Kisi bhi programming language me program tabhi useful banta hai jab woh user se data le sake aur uska result screen par dikha sake. Python me ye kaam bahut hi aasani se input() aur print() functions ki madad se kiya jata hai.
Is article me hum Python Input aur Output ko bilkul basic se samjhenge. Aap jaanenge ki print() function ka use kaise kiya jata hai, input() function user se data kaise leta hai, string ko number me kaise convert kiya jata hai, ek saath multiple values kaise input lete hain aur f-string ka use karke output ko professional tarike se kaise display karte hain.
Agar aapne abhi tak Python Tutorial in Hindi, Python Variables aur Python Data Types wale articles nahi padhe hain, to is article ke baad unhe bhi zarur padhein. Isse aapko Python ki fundamentals aur bhi achhe se samajh aayengi.
Python me Input aur Output kya hota hai?
Programming me Input ka matlab hota hai program ko data dena aur Output ka matlab hota hai program dwara result dikhana.
Udaharan ke liye agar kisi program me user apna naam enter karta hai aur program screen par "Hello Ankit" dikhata hai, to naam Input hai aur greeting message Output hai.
Har real-world application me Input aur Output ka bahut bada role hota hai.
Kuch examples:
- Login Form me Username aur Password lena
- Calculator me numbers lena
- ATM me PIN enter karna
- Online Shopping me Address fill karna
- Student Result System me Roll Number lena
In sabhi applications me pehle Input liya jata hai aur uske baad Output display kiya jata hai.
Python me Output kaise dikhaya jata hai?
Python me output dikhane ke liye print() function ka use kiya jata hai.
Ye Python ke sabse basic aur sabse zyada use hone wale functions me se ek hai.
Syntax
print(object)
Example
print("Hello, World!")
Output
Hello, World!
Yahan "Hello, World!" ek string hai jise print() function screen par display kar raha hai.
Variables ko Print karna
Sirf text hi nahi, variables ko bhi print kiya ja sakta hai.
name = "Ankit"
print(name)
Output
Ankit
Ek se adhik variables bhi print kar sakte hain.
name = "Ankit"
age = 22
city = "Lucknow"
print(name, age, city)
Output
Ankit 22 Lucknow
Python automatically values ke beech me space add kar deta hai.
print() Function ke Important Parameters
Bahut se beginners sirf print() use karte hain, lekin iske kuch useful parameters bhi hote hain.
sep Parameter
Jab multiple values print hoti hain tab unke beech separator define karne ke liye sep ka use kiya jata hai.
print("Python", "Java", "C++", sep=" | ")
Output
Python | Java | C++
Ye reports aur formatted output banane me kaafi useful hota hai.
end Parameter
By default print() statement ke baad next line aa jati hai.
Lekin agar aap same line me next output dikhana chahte hain to end parameter use karein.
print("Hello", end=" ")
print("World")
Output
Hello World
Ye menus, loading messages aur formatted output ke liye bahut useful hai.
Python me Input kaise lete hain?
Python me user se data lene ke liye input() function use hota hai.
Jab program input() tak pahunchta hai tab execution ruk jata hai aur program user ke input ka wait karta hai.
Syntax
input("Message")
Example
name = input("Enter your name: ")
print("Welcome", name)
Output
Enter your name: Rahul
Welcome Rahul
Yahan user jo bhi type karta hai wahi variable me store ho jata hai.
input() hamesha String Return karta hai
Ye ek bahut important point hai.
Chahe user number hi kyon na enter kare, input() usse string ke roop me store karta hai.
Example
age = input("Enter Age : ")
print(type(age))
Output
<class 'str'>
Isi wajah se beginners ko addition karte waqt problem hoti hai.
String ko Integer me Convert karna
Agar aap number par calculation karna chahte hain to pehle data type convert karna hoga.
age = int(input("Enter your age : "))
print(age + 5)
Output
Enter your age : 20
25
Yahan int() function string ko integer me convert kar raha hai.
Float Input lena
Decimal numbers ke liye float() function use kiya jata hai.
price = float(input("Enter Price : "))
print(price)
Output
99.99
Ye billing system, marks percentage aur scientific calculations me bahut useful hota hai.
Ek hi Line me Multiple Inputs lena
Kabhi-kabhi user se ek hi baar me do ya teen values leni hoti hain.
Iske liye split() method ka use kiya jata hai.
name, city = input("Enter Name and City : ").split()
print(name)
print(city)
Output
Rahul Delhi
Rahul
Delhi
Agar numbers lene hon to map() aur int() ka use kar sakte hain.
a, b = map(int, input("Enter Two Numbers : ").split())
print(a + b)
Output
10 20
30
Ye competitive programming aur real-world applications dono me kaafi use hota hai.
Real-Life Example
Maan lijiye aap ek simple student information program banana chahte hain.
name = input("Enter Student Name : ")
marks = float(input("Enter Marks : "))
print("Student :", name)
print("Marks :", marks)
Is tarah ka code school management system, result portal aur online forms me frequently use hota hai.
Common Mistake Beginners Karte Hain
Galat Code
a = input("Enter First Number : ")
b = input("Enter Second Number : ")
print(a + b)
Output
1020
Kyuki dono values string hain.
Sahi Code
a = int(input("Enter First Number : "))
b = int(input("Enter Second Number : "))
print(a + b)
Output
30
Isliye jab bhi calculations karni ho, int() ya float() ka use zarur karein.
