The document provides an overview of operators in Python, categorizing them into various types such as arithmetic, assignment, comparison, logical, bitwise, membership, and identity operators. Each type is explained with its function, syntax, and examples illustrating their use in performing computations and comparisons. The text emphasizes how operators can be combined with operands to execute specific operations within Python programming.

2. OPERATORS
• Operators are special symbols, combinations of symbols, or
keywords that designate some type of computation. You can
combine objects and operators to build expressions that
perform the actual computation.
• an operator is usually a symbol or combination of symbols
that allows you to perform a specific operation. This operation
can act on one or more operands.
• If the operation involves a single operand, then the operator
is unary. If the operator involves two operands, then the
operator is binary.

3. TYPES OF OPERATORS IN PYTHON
1. Arithmetic Operators
2. Assignment Operators
3. Comparison Operators
4. Logical Operators
5. Bitwise Operators
6. Membership Operators
7. Identity Operators

4. 1. Arithmetic Operators:
Arithmetic operators are used for performing
mathematical operations and are those operators that
allow you to perform arithmetic operations on numeric
values. OPERATORS SYMBOL MEANING
+ Addition
- Subtraction
* Multiplication
/ Division
% Remainder / Modulus
** Exponent
// Floor Division

5. Exponentiation is a mathematical operation that involves
raising a base number to the power of an exponent.
Exponentiation is done using the ** operator
Example:
23=2×2×2=8
result = 2 ** 3
print(result) # Output: 8

6. Floor Division
Floor division is a division operation that divides two numbers
and rounds down the result to the nearest integer.
floor division is done using the // operator
Example:
7÷2=3.57
Floor division: 7 // 2=3
result = 7 // 2
print(result) # Output: 3

7. 2. Assignment Operators :
The assignment operator is one of the most
frequently used operators in Python. The
operator consists of a single equal sign (=).
it operates on two operands.
The left-hand operand is typically a Variable,
while the right-hand operand is an expression.
number = 42
day = "Friday"
digits = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
letters = ["a", "b", "c"]

8. 3. Relational or Comparison Operators:
Comparison operators are used to compare Numerical
values and return True or False.
The comparison operators are all binary. This means
that they require left and right operands. These
operators always return a Boolean value (True or False)
that depends on the truth value of the comparison at
hand. OPERATORS OPERATIONS SYNTAX
== Equal to X == Y
!= Not Equal to X != Y
< Less than X < Y
<= Less than or equal to X <= Y
> Greater than X >Y
>= Greater than or
equal to
X >= Y

9. 4. Logical Operators:
Logical operators are used to perform logical operations on
Boolean values. They allow you to combine or manipulate the
results of comparisons.
OPERATORS SYNTAX DESCRIPTION EXAMPLES
And X and Y This returns True
if both x and y are true
x = 10
x > 5 and x < 15
Or X or Y This returns True
if either x or y are true
x = 10
x > 5 or x < 15
not not X Reverses a result, so
if something is True ,
not turns it False
x = 10
not(x > 5 and x < 15)

10. 5. Bitwise Operators:
Bitwise operators perform bitwise operations on integers. The
integers are first converted into binary and then operations are
performed on each bit or corresponding pair of bits.
OPERATOR NAME DESCRIPTION SYNTAX
& Bitwise AND
Result bit 1,if both operand bits are
1;otherwise results bit 0. x & y
| Bitwise OR Result bit 1,if any of the operand bit is 1;
otherwise results bit 0. x | y
~ Bitwise NOT inverts individual bits ~x
^ Bitwise XOR
Results bit 1,if any of the operand bit is 1 but
not both, otherwise
results bit 0.
x ^ y
>> Bitwise right shift
The left operand’s value is moved toward
right by the number of bits
specified by the right operand.
x>>
<< Bitwise left shift
The left operand’s value is moved toward
left by the number of bits
specified by the right operand.
x<<

11. 6. Membership Operator :
Membership operators in Python are operators
used to test whether a value exists in a
sequence, such as a list, tuple, or string.
Membership operators are used to test if a
sequence is presented in an object
OPERATOR DESCRIPTION EXAMPLE
in Returns True if a
sequence with the
specified value is
present in the object
x in y
not in Returns True if a
sequence with the
specified value is not
present in the object
x not in y

12. 7. Identity Operator :
Identity operators in Python are used to
compare the memory locations of two objects.
There are two identity operators: is and is not.
These operators return True if the specified
objects have the same memory address, and
False otherwise.

13. IDENTITY OPERATORS
OPERATOR DESCRIPTION EXAMPLE
is Returns true if both
variables are the same
object
x is y
Return true
is not Returns true if both
variables are not the same
object
x is not y
Return false
