x /= 5
print(x)  # Output: 4.0

Modulus Assignment (%=)

The modulus assignment operator (%=) calculates the modulus of the variable and a value, then assigns the result to the variable.

Example

x = 17
x %= 5
print(x)  # Output: 2

Python assignment operators are crucial for manipulating variables and performing various computations.

Comparison Operators

Python’s comparison operators let you compare two values and output the result as a Boolean value (True or False). These operators are frequently applied in loops and conditional statements. The most popular comparison operators are listed below:

Equal to (==)

The equal to operator (==) checks if two values are equal. It returns True if the values are the same; otherwise, it returns False.

Example

x = 5
y = 5
result = x == y
print(result)  # Output: True

Not Equal to (!=)

The not equal to operator (!=) checks if two values are not equal. It returns True if the values are different; otherwise, it returns False.

Example

x = 10
y = 5
result = x != y
print(result)  # Output: True

Greater Than (>)

The greater than operator (>) checks if the left operand is greater than the right operand. It returns True if the condition is met; otherwise, it returns False.

Example

x = 8
y = 5
result = x > y
print(result)  # Output: True

Less Than (<)

The less than operator (<) checks if the left operand is less than the right operand. It returns True if the condition is met; otherwise, it returns False.

Example

x = 3
y = 7
result = x < y
print(result)  # Output: True

Greater Than or Equal to (>=)

The greater than or equal to operator (>=) checks if the left operand is greater than or equal to the right operand. It returns True if the condition is met; otherwise, it returns False.

Example

x = 5
y = 5
result = x >= y
print(result)  # Output: True

Less Than or Equal to (<=)

The less than or equal to operator (<=) checks if the left operand is less than or equal to the right operand. It returns True if the condition is met; otherwise, it returns False.

Example

x = 3
y = 7
result = x <= y
print(result)  # Output: True

Python comparison operators are vital for decision-making and control flow in programs.

Logical Operators

Python’s logical operators let you combine many conditions and determine the truth value of each one. These operators are used to create complex conditions and decide how the programme should proceed based on the outcomes of the conditions. The most popular logical operators are listed below:

Logical AND (and)

The logical AND operator (and) returns True only if both operands are True; otherwise, it returns False.

Example

x = 5
y = 10
result = (x > 0) and (y < 15)
print(result)  # Output: True

Logical OR (or)

The logical OR operator (or) returns True if at least one operand is True; otherwise, it returns False.

Example

x = 5
y = 10
result = (x > 5) or (y < 15)
print(result)  # Output: True

Logical NOT (not)

The logical NOT operator (not) returns the opposite of the operand’s truth value. If the operand is True, it returns False, and if the operand is False, it returns True.

Example

x = 5
result = not (x == 5)
print(result)  # Output: False

Python logical operators are indispensable for handling complex conditions and controlling the program’s behavior based on those conditions.

Bitwise Operators

In Python, binary operations are carried out via bitwise operators. They are frequently used in low-level programming, networking, and graphics processing and modify individual bits. The most popular bitwise operators are listed below:

Bitwise AND (&)

The bitwise AND operator (&) performs a bitwise AND operation between two integer operands, bit by bit.

Example

x = 10  # 1010 in binary
y = 6   # 0110 in binary
result = x & y
print(result)  # Output: 2 (0010 in binary)

Bitwise OR (|)

The bitwise OR operator (|) performs a bitwise OR operation between two integer operands, bit by bit.

Example

x = 10  # 1010 in binary
y = 6   # 0110 in binary
result = x | y
print(result)  # Output: 14 (1110 in binary)

Bitwise XOR (^)

The bitwise XOR operator (^) performs a bitwise exclusive OR operation between two integer operands, bit by bit.

Example

x = 10  # 1010 in binary
y = 6   # 0110 in binary
result = x ^ y
print(result)  # Output: 12 (1100 in binary)

Bitwise NOT (~)

The bitwise NOT operator (~) performs a bitwise negation operation on a single integer operand, flipping all the bits.

Example

x = 10  # 1010 in binary
result = ~x
print(result)  # Output: -11 (-1011 in binary)

Left Shift (<<)

The left shift operator (<<) shifts the bits of an integer to the left by a specified number of positions, effectively multiplying the integer by 2 to the power of the shift count.

Example

x = 5  # 0101 in binary
result = x << 2
print(result)  # Output: 20 (10100 in binary)

Right Shift (>>)

The right shift operator (>>) shifts the bits of an integer to the right by a specified number of positions, effectively dividing the integer by 2 to the power of the shift count.

Example

x = 20  # 10100 in binary
result = x >> 2
print(result)  # Output: 5 (0101 in binary)

Python bitwise operators are essential for working with binary data and optimizing performance in specific applications.

Membership Operators

To determine whether a value is present in a sequence, such as a list, tuple, or string, Python uses membership operators. Depending on whether the value is included in the sequence, these operations either return True or False. The following list of frequently used membership operators:

In Operator

The in operator checks if a value is present in a sequence and returns True if the value exists; otherwise, it returns False.

Example

fruits = ["apple", "banana", "orange"]
result = "banana" in fruits
print(result)  # Output: True

Not In Operator

The not in operator checks if a value is not present in a sequence and returns True if the value does not exist; otherwise, it returns False.

Example

fruits = ["apple", "banana", "orange"]
result = "grape" not in fruits
print(result)  # Output: True

Membership operators are valuable for quickly determining the presence of a value in a collection of data.

Identity Operators

Python’s identity operators are used to compare the positions of two objects in memory. They establish whether or not two variables share the same memory location. The most typical identity operators are listed below:

Is Operator

The is operator returns True if two variables point to the same memory location; otherwise, it returns False.

Example

x = [1, 2, 3]
y = x
result = x is y
print(result)  # Output: True

Is Not Operator

The is not operator returns True if two variables do not point to the same memory location; otherwise, it returns False.

Example

x = [1, 2, 3]
y = [1, 2, 3]
result = x is not y
print(result)  # Output: True

Identity operators are crucial for understanding how Python handles object references and memory management.
