Python Variables In Hindi In Python Programming

Introduction to Python Programming In Hindi: Python ek aisi programming language hai jo seekhne aur use karne mein bahut aasan hai. Yeh ek high-level, interpreted, and general-purpose language hai jo beginners aur professionals dono ke liye useful hai. Python ki readability aur simplicity isse software development, web development, data analysis, artificial intelligence, aur scientific computing jaise fields mein popular banati hai. So Lets learn Python Variables In Hindi:

Python Variables In Hindi

Python Variables kisi memory ko diya gaya naam hai jo kisi value ko hold karti hai ya store karti hai. Matlab jab hum Variable define kar rahe hain toh hum memory mein value ko store karke use naam de rahe hote hain. Python mein variables ko define karna bahut simple hai aur iske liye kisi special character ki zaroorat nahi hoti. Simply, variable ko need ke according value assign kar di jati hai.

Python Variable Ka Example

Yahan par hum kuch examples dekhte hain jo Python variables ko demonstrate karte hain.

name = "Unlock Coding"
print(name)

Is code ko run karne par output hoga:

Unlock Coding

Python ek case sensitive language hai matlab koi bhi defined variable sirf usi name se accessible hoga. Matlab agar small letters mein variable define kiya gaya hai toh use capital letters se access nahi kar sakte. Dekhein niche example:

name = "Unlock Coding"
NAME = "UNLOCK CODING"
print(name)
print(NAME)

Is code ka output hoga:

Unlock Coding
UNLOCK CODING

Python Variables Update Karna

Python mein aap apni need ke according kisi bhi type ki value assign kar sakte hain, aur jab chahe us variable ki value ko nai value assign karke update kar sakte hain. Dekhein example:

var = 5
print(var)

# now assign it a new value.
var = 'hello'
print(var)

# again change.
var = True
print(var)

Is code ka output hoga:

5
hello
True

Python Variables Naming Rules

Python mein variables define karte waqt kuch baatein dhyan mein rakhni chahiye jaise:

1. Variables ke name kisi alphabet ya underscore (jaise: _name, name) se start hote hain. Variables ke name numbers se start nahi ho sakte hain.
2. Variables mein alphabets (A - z), numbers (0 - 9), aur underscore ( _ ) ho sakte hain.
3. Python case sensitive hoti hai matlab age aur Age do different variables honge.

Example of Valid and Invalid Variables

# These are invalid
8name = "Unlock"
full-name = "Unlock Coding"
full_name@ = "Unlock Coding"

# These are valid
_name = "Unlock"
full_name = "Unlock Coding"
full_name1 = "Unlock Coding"

Python Defining Multiple Variables

Python mein aap different - different tareeke se sirf ek single line mein multiple variables define kar sakte hain. Dekhein example:

name, age, address = 'Ram Kumar', 25, 'Uttar Pradesh, India'
print(name)
print(age)
print(address)

# You can also extract from a list
name, age, address = ['Ram Kumar', 25, 'Uttar Pradesh, India']
print(name)
print(age)
print(address)

Is code ka output hoga:

Ram Kumar
25
Uttar Pradesh, India

Ram Kumar
25
Uttar Pradesh, India

Python Constants

Baaki languages like PHP, Java, JavaScript ki tarah Python constants ko support nahi karta hai. Python mein variables ko constant banane ka koi built-in tareeka nahi hai, lekin aap naming convention ka use karke constants define kar sakte hain jaisa niche example mein hai:

MAX_SPEED = 120
PI = 3.14159

Variables as Containers

Python mein, ek variable ek container hota hai jo kisi bhi type ka data store kar sakta hai jaise number, string, list, tuple, dictionary, function, ya kisi aur data type ka. Yahan kuch examples hain:

# Number ko variable mein store karna
num = 10

# String ko variable mein store karna
name = "John"

# List ko variable mein store karna
my_list = [1, 2, 3, 4, 5]

In variables ka use aap apni program mein kahi bhi kar sakte hain:

print(num)       # 10 ko print karega
print(name)      # "John" ko print karega
print(my_list)   # [1, 2, 3, 4, 5] ko print karega

Multi-Word Variable Names

Python mein multi-word variable names ko different styles mein likha ja sakta hai:

Camel Case: Pehla word chhota aur har agla word bada hota hai.

fullName = "Unlock Coding"

Pascal Case: Har word bada hota hai.

FullName = "Unlock Coding"

Snake Case: Sabhi words chhote aur underscores se separated hote hain.

full_name = "Unlock Coding"

Assigning Multiple Values to Multiple Variables

Ek hi line mein multiple values ko different variables mein assign karne ke different tareeke hain:

a, b, c = 1, 2, 3

# Alag tareeke se
a = 1
b = 2
c = 3

Assigning a Single Value to Multiple Variables

Ek value ko multiple variables mein assign karne ka tareeka:

x = y = z = 10

# Alag tareeke se
x = 10
y = x
z = x

Variable Scope in Python

Python mein variables ka scope define karta hai ki variable ko program ke kin parts mein access kiya ja sakta hai. Variable do types ke scope mein ho sakte hain: local aur global.

Local Variable: Yeh function ke andar define hote hain aur sirf usi function ke andar accessible hote hain.

def my_function():
    x = 10
    print(x)

my_function()
# print(x)  # This will give an error since x is not accessible outside the function

Global Variable: Yeh function ke bahar define hote hain aur program ke kisi bhi part mein accessible hote hain.

x = 10

def my_function():
    print(x)

my_function()
print(x)

Using Global Keyword

Agar aap function ke andar global variable ko modify karna chahte hain toh global keyword ka use kar sakte hain.

x = 10

def my_function():
    global x
    x = 5

my_function()
print(x)  # Output will be 5

Dynamic Typing in Python

Python ek dynamically typed language hai matlab aap ek hi variable mein different types ki values assign kar sakte hain bina kisi type declaration ke.

var = 10
print(type(var))  # Output: <class 'int'>

var = "Hello"
print(type(var))  # Output: <class 'str'>

var = [1, 2, 3]
print(type(var))  # Output: <class 'list'>

Type Casting in Python

Kabhi kabhi humein ek type ki value ko dusre type mein convert karna padta hai. Is process ko type casting kehte hain.

# Integer to String
num = 10
num_str = str(num)
print(type(num_str))  # Output: <class 'str'>

# String to Integer
str_num = "123"
int_num = int(str_num)
print(type(int_num))  # Output: <class 'int'>

# Integer to Float
int_num = 5
float_num = float(int_num)
print(type(float_num))  # Output: <class 'float'>
