Subtraction (-)
Subtraction is achieved using the minus sign (-). It subtracts the right operand from the left operand and returns the difference. For example:
python
difference = 10 – 4
Here, `difference` will store the value `6`.
Multiplication (*)
Multiplication is performed with the asterisk (*) symbol. It multiplies two or more numbers together and returns the product. Consider this example:
python
product = 7 * 2
`product` will hold the value `14`. rummy ares login
Division (/) rummy modern apk
The division operator, represented by the forward slash (/), divides the left operand from the right. It returns a floating-point number as the result. For instance:
python
quotient = 15 / 3
In this case, `quotient` will contain the value `5.0`.
Modulus (%)
The modulus operator (%) calculates the remainder when the left operand is divided by the right. It is beneficial for tasks like checking for even or odd numbers. Example:
python top rummy apps
remainder = 17 % 4
`remainder` will hold the value `1`.
Exponentiation (**) rummy modern apk

Floor Division (//)
Floor division is similar to regular division but rounds down the result to the nearest integer. It is performed using double forward slashes (//). Example:
python
quotient = 17 // 3
`quotient` will contain the value `5`, as 17 divided by 3 results in 5 with no remainder.
2. Assignment Operators rummy modern apk
They assign values to variables and include the familiar “=” operator for simple assignments and compound operators like “+=”, “-=”, “*=”, and “/=” for combined operations.
Simple Assignment Operator (=)
It is used to assign a value to a variable. It takes the value on the right and assigns it to the variable on the left. For example:
python
x = 10
The value 10 is assigned to the variable `x`.
Compound Assignment Operators
Compound assignment operators combine the assignment operation with another operation like addition, subtraction, multiplication, division, or modulus. They provide a concise way to perform an operation on a variable and update its value simultaneously. Here are some examples:
- `+=`: Adds the right operand to the left and assigns the result to the left operand.
python
x += 5 # Equivalent to x = x + 5
- `-=`: Subtracts the right operand from the left and assigns the result to the left operand.
python
y -= 3 # Equivalent to y = y – 3
- `*=`: Multiplies the left operand by the right and assigns the result to the left operand.
python
z *= 2 # Equivalent to z = z * 2
- `/=`: Divides the left operand by the right and assigns the result to the left operand.
python
w /= 4 # Equivalent to w = w / 4
- `%=`: Calculates the modulus of the left operand with the right and assigns the result to the left operand.
python
a %= 7 # Equivalent to a = a % 7

3. Comparison Operators rummy modern apk
Comparison operators are essential for evaluating conditions and making decisions in your Python code. They include:
Equal to (==)
The “==” operator checks if two values are equal. It returns `True` if the values on both sides of the operator are the same and `False` otherwise. For example:
python
5 == 5 # True
7 == 3 # False
Not equal to (!=)
The “!=” operator evaluates whether two values are not equal. It returns `True` if the values are different and `False` if they are the same. For example:
python
7 != 3 # True
5 != 5 # False
Greater than (>)
The “>” operator checks if the value on the left exceeds the value on the right. It returns `True` if the condition is met and `False` otherwise. For example:
python
8 > 3 # True
5 > 10 # False
Less than (<)
The “<” operator examines whether the value on the left is less than the value on the right. It returns `True` if the condition is satisfied and `False` otherwise. For example:
python
2 < 7 # True
10 < 5 # False
Greater than or equal to (>=)
The “>=” operator determines if the value on the left is greater than or equal to the value on the right. It returns `True` if the condition holds and `False` otherwise. For example:
python
5 >= 5 # True
3 >= 8 # False
Less than or equal to (<=)
The “<=” operator checks if the value on the left is less than or equal to the value on the right. It returns `False` if the condition is not met and `True` otherwise. For example:
python
4 <= 5 # True
9 <= 3 # False

4. Logical Operators
They are used to perform logical operations on boolean values (True or False). Let’s delve deeper into Python’s three main logical operators: AND, OR, and NOT.
Logical AND (and)
The logical AND operator, denoted as “and” in Python, returns True if both operands are True; otherwise, it returns False. Here’s the truth table for the logical AND operator:
- True and True => True
- True and False => False
- False and True => False
- False and False => False
Practical Use
Logical AND is commonly used when multiple conditions need to be met before proceeding with an action. For example, in a cybersecurity context, you might use logical AND to check if a user has both the correct username and password before granting access to a system.
Logical OR (or)
The logical OR operator, denoted as “or” in Python, returns True if at least one of the operands is True; it returns False only if both operands are False. Here’s the truth table for the logical OR operator:
- True or True => True
- True or False => True
- False or True => True
- False or False => False
Practical Use
Logical OR is valuable when you want an action performed if any of the specified conditions are met. For example, in an artificial intelligence application, you might use logical OR to trigger a warning if any of the system’s sensors detect an anomaly.
Logical NOT (not)
The logical NOT operator, denoted as “not” in Python, reverses the boolean value of its operand. Here’s the truth table for the logical NOT operator:
- not True => False
- not False => True
Practical Use
Logical NOT is often employed to negate a condition. For instance, in a script that manages system updates, you might use logical NOT to check if a system update is unavailable before proceeding with other tasks.
5. Bitwise Operators
Bitwise AND (&)
This operator compares each bit of two integers and returns a new integer with bits set to 1 only if the corresponding bits in both operands are 1. In other words, it performs a bitwise “and” operation.
Example:
a = 5 # binary: 0101
b = 3 # binary: 0011
result = a & b # binary result: 0001 (decimal 1)
Bitwise OR (|)
It compares each bit of two integers and returns a new integer with bits set to 1 if at least one of the corresponding bits in both operands is 1. It performs a bitwise “or” operation.
Example:
a = 5 # binary: 0101
b = 3 # binary: 0011
result = a | b # binary result: 0111 (decimal 7)
Bitwise XOR (^)
The bitwise XOR (exclusive OR) operator compares each bit of two integers and returns a new integer with bits set to 1 if the corresponding bits in the operands are different. It performs a bitwise “exclusive or” operation.
Example:
a = 5 # binary: 0101
b = 3 # binary: 0011
result = a ^ b # binary result: 0110 (decimal 6)

Bitwise NOT (~)
The bitwise NOT operator inverts the bits of a single integer, turning 0s into 1s and 1s into 0s. It effectively flips all the bits.
Example:
a = 5 # binary: 0101
result = ~a # binary result: 1010 (decimal -6 due to two’s complement representation)
Left Shift (<<)
The left shift operator shifts the bits of an integer to the left by specified positions, filling the vacated positions with zeros. It effectively multiplies the number by 2 to the power of the shift amount.
Example:
a = 5 # binary: 0101
result = a << 2 # binary result: 010100 (decimal 20)
Right Shift (>>)
The right shift operator shifts the bits of an integer to the right by a specified number of positions, discarding the bits shifted out. It effectively divides the number by 2 to the power of the shift amount.
Example:
a = 20 # binary: 010100
result = a >> 2 # binary result: 000101 (decimal 5)
6. Special Operators
Python also offers special operators, such as the membership operators (in and not in) and the identity operators (is and is not). Membership operators check if a value is present in a sequence, while identity operators compare the memory addresses of two objects.
