Python Operator – Types of Operators in Python

Being a high level language where it can fit into most of the system it has the capability to handle the all data types.To handle this data the operators are categorized into below 7 categories .

  • Python Arithmetic Operator
  • Python Relational Operator
  • Python Assignment Operator
  • Python Logical Operator
  • Python Membership Operator
  • Python Identity Operator
  • Python Bitwise Operator

Python Arithmetic Operator

Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication etc.

OperatorMeaningExample
+Add two operands or unary plusx + y
+2
Subtract right operand from the left or unary minusx – y
-2
*Multiply two operandsx * y
/Divide left operand by the right one (always results into float)x / y
%Modulus – remainder of the division of left operand by the rightx % y (remainder of x/y)
//Floor division – division that results into whole number adjusted to the left in the number linex // y
**Exponent – left operand raised to the power of rightx**y (x to the power y)

Python Relational Operator

Relational operators are used to compare values. It either returns True or False according to the condition.

OperatorMeaningExample
>Greater that – True if left operand is greater than the rightx > y
<Less that – True if left operand is less than the rightx < y
==Equal to – True if both operands are equalx == y
!=Not equal to – True if operands are not equalx != y
>=Greater than or equal to – True if left operand is greater than or equal to the rightx >= y
<=Less than or equal to – True if left operand is less than or equal to the rightx <= y

Python Assignment Operator

Assignment operators are used in Python to assign values to variables.

a = 5 is a simple assignment operator that assigns the value 5 on the right to the variable a on the left.

There are various compound operators in Python like a += 5 that adds to the variable and later assigns the same. It is equivalent to a = a + 5.

OperatorExampleEquivatent to
=x = 5x = 5
+=x += 5x = x + 5
-=x -= 5x = x – 5
*=x *= 5x = x * 5
/=x /= 5x = x / 5
%=x %= 5x = x % 5
//=x //= 5x = x // 5
**=x **= 5x = x ** 5
&=x &= 5x = x & 5
|=x |= 5x = x | 5
^=x ^= 5x = x ^ 5
>>=x >>= 5x = x >> 5
<<=x <<= 5x = x << 5

Python Logical Operator

Logical operators are the andornot operators.

OperatorMeaningExample
andTrue if both the operands are truex and y
orTrue if either of the operands is truex or y
notTrue if operand is false (complements the operand)not x

Python Membership Operator

in and not in are the membership operators in Python. They are used to test whether a value or variable is found in a sequence (stringlisttupleset and dictionary).

In a dictionary we can only test for presence of key, not the value.

OperatorMeaningExample
inTrue if value/variable is found in the sequence5 in x
not inTrue if value/variable is not found in the sequence5 not in x

Python Identity Operator

is and is not are the identity operators in Python. They are used to check if two values (or variables) are located on the same part of the memory. Two variables that are equal does not imply that they are identical.

OperatorMeaningExample
isTrue if the operands are identical (refer to the same object)x is True
is notTrue if the operands are not identical (do not refer to the same object)x is not True

Python Bitwise Operator

Bitwise operators act on operands as if they were string of binary digits. It operates bit by bit, hence the name.

For example, 2 is 10 in binary and 7 is 111.

In the table below: Let x = 10 (0000 1010 in binary) and y = 4 (0000 0100 in binary)

OperatorMeaningExample
&Bitwise ANDx& y = 0 (0000 0000)
|Bitwise ORx | y = 14 (0000 1110)
~Bitwise NOT~x = -11 (1111 0101)
^Bitwise XORx ^ y = 14 (0000 1110)
>>Bitwise right shiftx>> 2 = 2 (0000 0010)
<<Bitwise left shiftx<< 2 = 40 (0010 1000)
