Print(12 >= 10)

# Less than or equal to
Print(15 <= 20)

Assignment Operators

Assignment operators assign values to variables and perform operations simultaneously. The most common assignment operator is the "equal to" symbol (=). However, there are other assignment operators used in Python programming.

# Assign
x = 10

# Addition assignment
x += 5

# Subtraction assignment
x -= 3

# Multiplication assignment
x *= 2

# Division assignment
x /= 4

# Modulus assignment
x %= 3

# Exponent assignment 
x **= 5

# Remainder Assignment 
x %= 2

# Floor Division Assignment 
x //= 9

Logical Operators

They evaluate multiple conditions at the same time. There are three logical operators, namely; "AND", "OR" and "NOT". The result of logical operators is always a boolean (True, False)

# "AND" Operator
x = 2
y = 15
Print(x > 1 and y < 18)  # Output: True
Print(x < 0 and y < 20)  # Output: False

# "OR" Operator
x = 4
y = 9
Print(x > 0 or y < 20)   # Output: True
Print(x < 0 or y < 20)   # Output: True
print(x < 0 or y > 20)   # Output: False

# "NOT" Operator
x = True
Print(not x)  # Output: False

y = False
Print(not y)  # Output: True

Bitwise Operators

Have you ever wondered how you can extract specific bits from an integer without affecting others? Bitwise operators are typically utilized to execute bitwise operations on integer-type entities. Rather than regarding the entity as a whole, it is interpreted as a sequence of individual bits. Python has six bitwise operators: &, |, ^, ~, <<, and >>. Except ~, all these operators are binary, meaning they manipulate two operands. Each operand represents a binary digit (bit), 1 or 0.

Conclusion

Python has a wide range of operators, including arithmetic, comparison, logical, and bitwise operators, each serving specific purposes in programming.
