5.1 Python Operators Cheat Sheet

 

Python Operators Cheat Sheet 

Python के सभी प्रमुख Operators की यह quick-reference sheet है। इसे सीखने, coding करते समय reference के रूप में इस्तेमाल करने और Stock Market Algo Trading के उदाहरणों को समझने के लिए बनाया गया है।

1. Comparison Operators

Operator	Meaning	Example	Result
==	Equal to	5 == 5	True
!=	Not equal to	5 != 3	True
>	Greater than	5 > 3	True
<	Less than	5 < 3	False
>=	Greater than or equal to	5 >= 5	True
<=	Less than or equal to	3 <= 5	True

2. Arithmetic Operators

Operator	Meaning	Example	Result
+	Addition	10 + 5	15
-	Subtraction	10 - 5	5
*	Multiplication	10 * 5	50
/	Division	10 / 5	2.0
//	Floor division	11 // 5	2
%	Remainder	11 % 5	1
**	Power	2 ** 3	8

3. Assignment Operators

Operator	Example	Equivalent
=	x = 10	Value assign करना
+=	x += 5	x = x + 5
-=	x -= 5	x = x - 5
*=	x *= 2	x = x * 2
/=	x /= 2	x = x / 2
//=	x //= 2	x = x // 2
%=	x %= 3	x = x % 3
**=	x **= 2	x = x ** 2
&=	x &= 3	Bitwise AND assignment
\|=	x \|= 3	Bitwise OR assignment
^=	x ^= 3	Bitwise XOR assignment
<<=	x <<= 1	Left-shift assignment
>>=	x >>= 1	Right-shift assignment

4. Logical Operators

Operator	Meaning	Example	Result
and	दोनों conditions True	5 > 3 and 8 > 6	True
or	कम-से-कम एक True	5 < 3 or 8 > 6	True
not	Boolean उलटना	not True	False

5. Membership Operators

Operator	Meaning	Example	Result
in	मौजूद है	"a" in "apple"	True
not in	मौजूद नहीं है	"z" not in "apple"	True

6. Identity Operators

Operator	Meaning	Example
is	दोनों एक ही Object हैं	x is y
is not	दोनों अलग Objects हैं	x is not y

x = [1, 2]y = xz = [1, 2]print(x == z)  # Trueprint(x is z)  # Falseprint(x is y)  # True

== Values की तुलना करता है, जबकि is Object Identity की।

7. Bitwise Operators

Operator	Meaning	Example	Result
&	Bitwise AND	5 & 3	1
\|	Bitwise OR	5 \| 3	7
^	Bitwise XOR	5 ^ 3	6
~	Bitwise NOT	~5	-6
<<	Left shift	5 << 1	10
>>	Right shift	5 >> 1	2

8. Conditional Expression

price = 520target = 500signal = "Target Reached" if price >= target else "Target Not Reached"print(signal)

Output: Target Reached

9. Algo Trading में Operators का उपयोग

current_price = 520target_price = 500volume = 150000if current_price >= target_price and volume > 100000:    print("Conditions Met")else:    print("Conditions Not Met")

यहाँ >=, > और and मिलकर दो conditions जाँचते हैं।

याद रखने योग्य बातें

• = → Assignment

• == → Equality comparison

• != → Not equal

• >= → Greater than or equal to

• <= → Less than or equal to

• and, or, not → Logical operations

• in, not in → Membership

• is, is not → Object identity
