Python operators – all in one video (with real examples) #5 || Python ka Pitara || DeathCode - DeathCode

Python Series – Part 5: Python ke Operators (Full Guide)

📌 Video Focus:

  • Python ke 7 types ke operators
  • Har ek ka syntax, example, real-life analogy
  • Logical difference between ==, is, in
  • Bonus: Type coercion aur truthy/falsy concept quick recap

🎉 Introduction

"To bhai, pichle video me humne sikha Python me decision lena kaise hota hai.

Lekin agar condition likhni ho to usme ==, >, < ye sab kya hote hain?

Aaj ke video me hum deep dive karenge Python ke Operators me — bina confuse hue, real-life examples ke sath."

🔢 Section 1: Arithmetic Operators

"Jaise maths me plus, minus, multiply hota hai, waise hi programming me bhi."

Operator Use Example
+ Addition 2 + 3 = 5
- Subtraction 5 - 2 = 3
* Multiplication 3 * 4 = 12
/ Division 10 / 2 = 5.0
// Floor Division 10 // 3 = 3
% Modulus 10 % 3 = 1
** Exponent 2 ** 3 = 8

"Shopping app me price calculation, EMI calculations sab me arithmetic operators lagte hain."

🧠 Section 2: Comparison / Relational Operators

"Jab Python ko compare karwana ho — tab ye use aate hain."

Operator Use Example
== Equal to 5 == 5 → True
!= Not equal to 5 != 4 → True
> Greater than 7 > 3
< Less than 2 < 8
>= Greater than or equal to 7 >= 7
<= Less than or equal to 5 <= 5

"Dhyan rahe: = assign karta hai, == compare karta hai."

"Age check, marks comparison, discount logic me inka use hota hai."

⚡ Section 3: Logical Operators

"Multiple condition check karne ke liye and, or, not ka use hota hai."

if age >= 18 and has_voter_id:
    print("You can vote")
 
if not is_logged_in:
    print("Please login")
Operator Meaning
and Dono true hone chahiye
or Koi ek bhi true ho
not Result ulta kar deta hai

"Login + subscription jaise real world checks yahi handle karte hain."

📦 Section 4: Assignment Operators

"Jab kisi variable me value assign ya update karni hoti hai."

Operator Use Example
= Assign a = 5
+= Add and assign a += 3
-= Subtract and assign a -= 2
*= Multiply and assign a *= 4
/= Divide and assign a /= 2

"Counters, scores, balance update, yahi sab assignment operations se hota hai."

🧬 Section 5: Identity Operators

"Python me == aur is alag cheezein hain."

a = [1, 2, 3]
b = a
c = [1, 2, 3]
 
print(a == c)    # True
print(a is c)    # False
print(a is b)    # True

"== value compare karta hai, jabki is memory location."

"Isme dikkat tab aati hai jab same value hone ke bawajood objects alag memory me store ho."

🔍 Section 6: Membership Operators

"Check karna hai koi item kisi group me hai ya nahi?"

fruits = ['apple', 'banana', 'mango']
 
if 'banana' in fruits:
    print("Yes")
Operator Use
in Check existence
not in Check non-existence

"Search bar, access control, validations sab me membership operator use hota hai."

🛠️ Section 7: Bitwise Operators

"Ye thoda advanced hai — mostly hardware ya optimization me use hote hain."

Operator Meaning
& AND
` `
^ XOR
~ NOT
<< Left Shift
>> Right Shift

"Detail me jab hum optimization aur low-level computing karenge tab aur seekhenge."

🔖 Section 8: Bonus – Truthy and Falsy Values

"Python me kuch values by default False hoti hain."

if 0:          # False
if "":        # False
if []:        # False
if {}:        # False
if None:      # False

"Empty values, zero, None sab False treat hote hain — isko yaad rakhna bugs se bachne ke liye."

🚀 Outro & Next Video Teaser

"To bhai, aaj ke video me humne poore Python Operators ko cover kiya:

  • Arithmetic
  • Comparison
  • Logical
  • Assignment
  • Identity
  • Membership
  • Bitwise (Intro)

Agla video hoga sabse zyada mazedaar — Loops!

Repeat hone wale tasks, automation, games sab loops se hi possible hote hain.

So ready raho, milte hain next part me! 🔥"
