Python Operators (The Superpowers of Your Code!)

Imagine Python as a magical world where values are little creatures…
And operators are the spells that make them move, fight, compare, and transform. 🪄🐍

Every time you write +, ==, or and, you’re basically whispering a command to Python:

“Hey, do this. And be quick about it.”

Let’s explore the most important operators — in a fun and interactive way!

1. Introduction: What Are Operators?

Operators are symbols or keywords that tell Python what action to perform.

Think of them as:

• The plus sign waving its hand and saying, “Let’s join forces!”
• The comparison operators judging things like a reality show panel 👀
• The logical operators making decisions like a wise monk.

You use operators every single time you code — even if you don’t notice.

2. Arithmetic Operators (Your Math Superheroes)

These operators work with numbers.
They’re the Avengers of the Python world (but with less CGI).

Operator	Meaning	Example	Result
+	Addition	10 + 5	15
-	Subtraction	10 - 3	7
*	Multiplication	6 * 4	24
/	Division	10 / 4	2.5
//	Floor Division	10 // 4	2 (no decimals)
%	Modulus	10 % 4	2 (remainder)
**	Exponent	3 ** 3	27

Quick Example

a = 15
b = 4
print(a // b)   # Output: 3
print(a % b)    # Output: 3

Floor division and modulus are siblings:
one gives the quotient, the other gives the remainder.

3. Comparison Operators (Judging Mode ON 😎)

These operators compare two values.

Operator	Meaning	Example	Result
==	Equal to	5 == 5	True
!=	Not equal to	5 != 3	True
>	Greater than	10 > 8	True
<	Less than	2 < 9	True
>=	Greater or equal	5 >= 5	True
<=	Less or equal	3 <= 5	True

Example

age = 18
print(age >= 18)  # True

Python’s way of saying:
“You’re officially an adult… in this variable.”

4. Logical Operators (The Wise Decision-Makers)

These operators combine conditions.
Like checking multiple items on your to-do list.

AND

All conditions must be true.

age = 25
has_id = True
print(age >= 18 and has_id)  # True

OR

At least one condition must be true.

is_member = False
has_coupon = True
print(is_member or has_coupon)  # True

NOT

Flips True to False and vice-versa.

is_raining = False
print(not is_raining)  # True

Logical operators = Python’s brain. 🧠

5. Practical Examples & Common Mistakes

✔ Example 1 — Checking if a number is even

num = 12
if num % 2 == 0:
    print("Even number!")

✔ Example 2 — Login check

username = "amit"
password = "1234"

if username == "amit" and password == "1234":
    print("Welcome back!")

❌ Common Mistake 1 — Mixing = and ==

= is assignment
== is comparison

x = 10     # correct
x == 10    # comparison only

❌ Common Mistake 2 — Confusing / and //

/ → decimal
// → whole number
