Python Variable in Hindi || Learn Programming in Hindi | Programming Warrior

Variable: Variable Ek container hai (box)  Jha hum value store karte hai. Variable programmer apni marzii sa kuch bhi le sakta hai .

For example: Agar apke pass x ki value 2 hai ,

x = 2

x----------------Variable

2----------------Value

To x isme variable hai or 2 uski value hai jo humne x mein store ki hai ,
Hum isko aise bhi lik sakte hai spam = 40

spam -----------Variable

40----------------Value

Variable ke ander hum kya kya store kar sakte hai ?

* Variable ke ander hum koi bhi data type, string, floating no etc store kar sakte hai
* Hum variable ki value bhi change kar sakte hai

For Examle:
a=2
print(a)

Output: 2

But agar hum a ki value 4 rakte hai or print(a) use kartega to abb a ki value 2 sa change ho kar 4 ho jayeggi , Necha diye example mein app dek sakte hai.

a = 2

print(a)

Output: 2

Or

a = 2

print(a)

a=4

print(a)

Output: 2

4

Abb app dek sakte hai a ki value 4 hai , App isko pratice kro app samaj jaogee

Variable Ke Rules:

Rule no 1. Variable ka naam number sa start nahi kar sakte, but bech mein use kar sakte hai.
example : 1number = 4    |     num1 = 4
                 error                |      Right

Rule no 2. Hum variable ka naam kisi bhi letter sa start kar sakte hai , Hum _underscore ka bhi use kar sakte hai.
example :    _name = "Rakshak"
                          or
                    my_name = "Rakshak"

Rule no 3. Koi special symbol hum variable mein use nahi kar sakte
example : @,$ etc

Good Variable = spam, eggs, spam12, _name

Bad Variable = 12spam, #sign, var.12

Different = spam, Spam, SPAM


Note 1 : Agar variable name ek sa zyada words ka use karna hai to _underscore ka use karna chaye

my_fathers_name = "Arjun singh"

Isko hum "Snake case writing " bhi bolte hai

Note 2 : Hum isko aise bhi lik sakte hai

MyFatherName="Arjun Singh"

Isko hum " Camel Case Writing " bolte hai , but underscore vala zyada better hota hai , Vo app par depend krta hai.

I hope apko variable acha sa samaj a gaya hoga agar fir bhi apko kuch problem hogi to comment karke bta sakte ho.
