Python Operators – All types with examples.
An operator is a special symbol that operates over variables, values, and other types. On success, it gives an outcome. For example + is an arithmetic operator that applies to two operands and the result is the sum of two values. In this tutorial, you will learn, all types of operators in Python with examples.
What are all types of operators in Python?
- Arithmetic Operators ( +, – , * etc.) – For basic mathematical operations, add, subtract etc.
- Relational Operators (>, < , == etc.) – For comparing values.
- Logical Operators (and, or etc) –
- Assignment Operators ( =, +=, etc) –
- Bitwise operators (|, & etc.) –
- Identity Operator –
- Membership Operator.
What Arithmetic Operators do?
They are used for basic mathematical functionality, such as addition, multiplication, subtraction, etc. The following table list all arithmetic operators.
|+ , -, /, *, %,||Works on two Operands|
+ Adds two numbers
– Subtract two numbers
/ Divides one number from another
* Multiply two numbers
% Modulus operator returns the remainder on division.
|//, **||// Floor division – Returns the smallest integer of the result.|
** Exponential, One operand is the power of another
Relational Operators – Compare two Operands
Using a relation operator, you can compare two values. The result is a boolean value, either True or False. The following table lists all comparison operators in Python.
|>, < , ==, != , >=, <=||> , more than |
< , less than
== , equal
!= , not equal
>= , more than or equal
<= , less than or equal
print(x >= y);
Assignment Operators – Update or Initialize the content of a variable.
With assignment operators, you can set the value of a variable. Works on two (left and right) operands. The left side is a variable, the right side could be, an expression, a constant, or another variable. Following is the list of all assignment operators in Python.
|Assignment Operators||Description||Python Example||Output|
|=||Assigns a value from left to right||5|
|+=, -= etc.||We can also use an assignment operator with another operator. The x += y, expends x = x + y;||5|
Bitwise operators – Works at the bit level
A bit operator works on an individual bit level. For example, when we do a bitwise OR of two variables, each bit at the same positions from each variable is ORRED and the resulting bit is returned. Below is the list of all bitwise operators.
|Bitwise Operators||Description||Code example||Output|
|&, |, >>, >>||& End, |
>> Right Shift,
<< Left Shift
|X is 101|
Y is 1001
X&Y is 1
X|Y is 1101
X >> 1 is 10
Y << 1 is 10010
|^, ~||^ Bitwise XOR, ~Bitwaise Not||X is 101|
Y is 1001
X^Y is 1100
~Y is -1010
Logical Operators – Operands values are Ored, ends, or not.
|Logical Operators||Description||Example Code||Output|
|and, or, not||end and or, Works on two Operands (e.g X and Y).|
and, Returns true, if both the operands are true (not zero).
or, Returns true, if any of the operands is true (not zero).
not work on a single operand, it
returns the complement of an operand.
|X and Y are 9|
X and Z are True
X and M are False
X or Y is 5
X or Z is 5
X or M is 5
not X False
not Y False
not M True
Identity and Membership Operators:
Identity operators are special operators. There are two identity operators,
is not. With is not we compare the two memory locations. Following is an example.
X = 5; Y = 6; Z = 6; print(X is not Y) print(X is Z) print(Y is Z)
True False True
Membership Operators – To check if a value belongs to a sequence?
not in are the two membership operators, to find the presence of a value in the sequence e.g string, tuple, dictionary, etc.
in – Returns true if a value is present.
not in – Returns True if a value is absent.
String = 'Hello Python'; print('P' in String); print('K' not in String); print('Z' in String);
True True False
