Python operators types and examples with code pdf for class 11, 12 cbse download 2021

Python divides the operators in the following groups:
Arithmetic operators
Assignment operators
Comparison operators
Logical operators
Identity operators
Membership operators
Bitwise operators

Python Arithmetic Operators
Arithmetic operators are used with numeric values to perform common mathematical operations:
Operator


Name, Example

+
Addition
x + y


Subtraction
x – y

*
Multiplication
x * y

/
Division
x / y
………………


%
Modulus
x % y

**
Exponentiation
x ** y
……………
//
Floor division
x // y

Python Assignment Operators
Assignment operators are used to assign values to variables:
Operator
Example
Same As

=
x = 5
x = 5

+=
x += 3
x = x + 3
Try it »
-=
x -= 3
x = x – 3

*=
x *= 3
x = x * 3

/=
x /= 3
x = x / 3

%=
x %= 3
x = x % 3

//=
x //= 3
x = x // 3

**=
x **= 3
x = x ** 3

&=
x &= 3
x = x & 3

|=
x |= 3
x = x | 3

^=
x ^= 3
x = x ^ 3

=
x >>= 3
x = x >> 3

<<=
x <<= 3
x = x << 3

Python Comparison Operators
Comparison operators are used to compare two values:
Operator
Name
Example

Operator name with example

Equal
x == y

!=
Not equal
x != y

>
Greater than
x > y

<
Less than
x < y

=
Greater than or equal to
x >= y

<=
Less than or equal to
x <= y

Python Logical Operators
Logical operators are used to combine conditional statements:
Operator
Description
Example

and
Returns True if both statements are true
x < 5 and x < 10

or
Returns True if one of the statements is true
x < 5 or x < 4

not
Reverse the result, returns False if the result is true
not(x < 5 and x < 10)

Python Identity Operators
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:
Operator
Description
Example

is
Returns True if both variables are the same object
x is y

is not
Returns True if both variables are not the same object
x is not y

Python Membership Operators
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
Try it »

Python Bitwise Operators
Bitwise operators are used to compare (binary) numbers:
Operator
Name
Description
&
AND
Sets each bit to 1 if both bits are 1


|
OR
Sets each bit to 1 if one of two bits is 1
^
XOR
Sets each bit to 1 if only one of two bits is 1
~
NOT
Inverts all the bits
<<
Zero fill left shift
Shift left by pushing zeros in from the right and let the leftmost bits fall off

>
Signed right shift
Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off
