Arithmetic Operators

Arithmetic operators allow us to perform basic mathematical calculations in Python. They include addition, subtraction, multiplication, division, modulus, and exponentiation.

Addition

The addition operator (+) is used to add two operands together. For example:

python
result = 10 + 5
print(result)  # Output: 15

Subtraction

The subtraction operator (-) subtracts the second operand from the first operand. Here's an example:

python
result = 10 - 5
print(result)  # Output: 5

Multiplication

The multiplication operator (*) multiplies two operands. Here's an example:

python
result = 10 * 5
print(result)  # Output: 50

Division

The division operator (/) divides the first operand by the second operand. It returns the quotient as a floating-point number. Example:

python
result = 10 / 5
print(result)  # Output: 2.0

Modulus

The modulus operator (%) returns the remainder when the first operand is divided by the second operand. Example:

python
result = 10 % 3
print(result)  # Output: 1

Exponentiation

The exponentiation operator (**) raises the first operand to the power of the second operand. Example:

python
result = 2 ** 3
print(result)  # Output: 8

Assignment Operators

Assignment operators are used to assign values to variables. They include simple assignment, addition assignment, subtraction assignment, multiplication assignment, division assignment, and more.

Simple Assignment

The simple assignment operator (=) assigns the value on the right to the variable on the left. Example:

python
x = 10

Addition Assignment

The addition assignment operator (+=) adds the value on the right to the variable on the left and assigns the result to the variable. Example:

python
x += 5  # Equivalent to x = x + 5

Subtraction Assignment

The subtraction assignment operator (-=) subtracts the value on the right from the variable on the left and assigns the result to the variable. Example:

python
x -= 5  # Equivalent to x = x - 5

Multiplication Assignment

The multiplication assignment operator (*=) multiplies the variable on the left by the value on the right and assigns the result to the variable. Example:

python
x *= 5  # Equivalent to x = x * 5

Division Assignment

The division assignment operator (/=) divides the variable on the left by the value on the right and assigns the result to the variable. Example:

python
x /= 5  # Equivalent to x = x / 5

Comparison Operators

Comparison operators are used to compare values and return a boolean result (True or False). They include equal to, not equal to, greater than, less than, greater than or equal to, and less than or equal to.

Equal To

The equal to operator (==) checks if the operands are equal. Example:

python
result = 10 == 5
print(result)  # Output: False

Not Equal To

The not equal to operator (!=) checks if the operands are not equal. Example:

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

Greater Than

The greater than operator (>) checks if the first operand is greater than the second operand. Example:

python
result = 10 > 5
print(result)  # Output: True

Less Than

The less than operator (<) checks if the first operand is less than the second operand. Example:

python
result = 10 < 5
print(result)  # Output: False

Greater Than or Equal To

The greater than or equal to operator (>=) checks if the first operand is greater than or equal to the second operand. Example:

python
result = 10 >= 5
print(result)  # Output: True

Less Than or Equal To

The less than or equal to operator (<=) checks if the first operand is less than or equal to the second operand. Example:

python
result = 10 <= 5
print(result)  # Output: False

Logical Operators

Logical operators are used to perform logical operations on boolean values. They include AND, OR, and NOT.

AND Operator

The AND operator (and) returns True if both operands are True. Example:

python
result = True and False
print(result)  # Output: False

OR Operator

The OR operator (or) returns True if at least one of the operands is True. Example:

python
result = True or False
print(result)  # Output: True

NOT Operator

The NOT operator (not) negates the boolean value of the operand. Example:

python
result = not True
print(result)  # Output: False

Bitwise Operators

Bitwise operators perform operations on binary representations of numbers. They include bitwise AND, bitwise OR, bitwise XOR, bitwise NOT, left shift, and right shift.

Bitwise AND

The bitwise AND operator (&) performs a bitwise AND operation between two operands. Example:

python
result = 5 & 3
print(result)  # Output: 1

Bitwise OR

The bitwise OR operator (|) performs a bitwise OR operation between two operands. Example:

python
result = 5 | 3
print(result)  # Output: 7

Bitwise XOR

The bitwise XOR operator (^) performs a bitwise exclusive OR operation between two operands. Example:

python
result = 5 ^ 3
print(result)  # Output: 6

Bitwise NOT

The bitwise NOT operator (~) performs a bitwise negation of the operand. Example:

python
result = ~5
print(result)  # Output: -6

Left Shift

The left shift operator (<<) shifts the bits of the first operand to the left by the number of positions specified by the second operand. Example:

python
result = 5 << 2
print(result)  # Output: 20

Right Shift

The right shift operator (>>) shifts the bits of the first operand to the right by the number of positions specified by the second operand. Example:

python
result = 5 >> 2
print(result)  # Output: 1

Membership Operators

Membership operators are used to test if a sequence is present in an object. They include in and not in.

in Operator

The in operator returns True if a value is found in the specified sequence. Example:

python
my_list = [1, 2, 3, 4, 5]
result = 3 in my_list
print(result)  # Output: True

not in Operator

The not in operator returns True if a value is not found in the specified sequence. Example:

python
my_list = [1, 2, 3, 4, 5]
result = 6 not in my_list
print(result)  # Output: True

Identity Operators

Identity operators are used to compare the memory locations of two objects. They include is and is not.

is Operator

The is operator returns True if both operands refer to the same object. Example:

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

is not Operator

The is not operator returns True if both operands do not refer to the same object. Example:

python
x = 5
y = 6
result = x is not y
print(result)  # Output: True
