In our previous posts, we covered logical and arithmetic operators in Python. Now, let's take a deep dive into comparison (relational) operators, followed by bitwise and assignment operators, which play a crucial role in data processing and optimization.
🔍 Understanding Comparison (Relational) Operators
As the name suggests, comparison operators are used to compare two values and determine relationships like greater than, lesser than, or equality. They are fundamental in decision-making processes in programming.
📌 Examples of Comparison Operators in Action
print(10 > 3) # True (10 is greater than 3)
print(10 >= 10) # True (10 is equal to 10)
print(5 < 8) # True (5 is less than 8)
print(7 <= 7) # True (7 is equal to 7)
print(4 == 4) # True (Both values are equal)
print(6 != 9) # True (6 is not equal to 9)
List of Python Comparison Operators
Greater than 10 > 3 True
< Less than 5 < 8 True
= Greater than or equal to 10 >= 10 True
<= Less than or equal to 7 <= 7 True
== Equal to 4 == 4 True
!= Not equal to 6 != 9 True
🔥 Where Are Comparison Operators Used?
Comparison operators are commonly used in conditional statements, loops, and filtering data.
age = 18
if age >= 18:
print("You are eligible to vote!")
else:
print("You are not eligible to vote.")
Bitwise Operators in Python
Bitwise operators allow us to perform operations at the binary level (bit by bit). These operators are commonly used in low-level programming, cryptography, and optimizing algorithms.
🔹 Examples of Bitwise Operators
Let’s take a simple example using 5 and 3:
a = 5 # Binary: 0101
b = 3 # Binary: 0011
print(a & b) # AND -> 1 (Binary: 0001)
print(a | b) # OR -> 7 (Binary: 0111)
print(a ^ b) # XOR -> 6 (Binary: 0110)
print(~a) # NOT -> -6 (Binary: Inverts bits)
print(a << 1) # Left Shift -> 10 (Binary: 1010)
print(b >> 1) # Right Shift -> 1 (Binary: 0001)
📊** List of Bitwise Operators**
(a=5, b=3)
& Bitwise AND 5 & 3 0001 1
Bitwise OR 5 3
^ Bitwise XOR 5 ^ 3 0110 6
~ Bitwise NOT ~5 -0110 -6
<< Left Shift 5 << 1 1010 10
Right Shift 3 >> 1 0001 1
🔥 Where Are Bitwise Operators Used?
Cryptography 🛡️ (e.g., encryption algorithms)
Image Processing 🖼️ (pixel manipulation)
Low-level System Operations 🖥️ (memory optimization)
Fast Computations ⚡ (bitwise tricks can replace arithmetic operations)
Assignment Operators in Python
Assignment operators modify variables efficiently by performing operations and storing the result in the same variable.
🔹 Examples of Assignment Operators
x = 10 # Simple assignment
x += 5 # Equivalent to x = x + 5
x -= 2 # Equivalent to x = x - 2
x *= 3 # Equivalent to x = x * 3
x /= 2 # Equivalent to x = x / 2
x %= 3 # Equivalent to x = x % 3
x //= 2 # Equivalent to x = x // 2
x **= 2 # Equivalent to x = x ** 2
📊 List of Assignment Operators
= Assign value x = 10 10
+= Add and assign x += 5 15
-= Subtract and assign x -= 2 8
= Multiply and assign x *= 3 30
/= Divide and assign x /= 2 5.0
%= Modulus and assign x %= 3 2
//= Floor divide and assign x //= 2 5
*= Exponentiate and assign x **= 2 100
🔥 Where Are Assignment Operators Used?
Mathematical Calculations (shortcuts in algebraic operations)
Updating Variables in Loops (x += 1 for counter increments)
Game Development (modifying game scores, physics updates)
Data Processing (efficient calculations in big data applications)
