Python Operator and its types
Hey Guys! If you are worried about Python Operator and its types than you are on right place to learn. Here You will learn all python operators in details.
What is Operator ?
- An Operator is a symbol that tells the compiler to perform specific mathemetical or logical function.Operator can be unary,binary or ternory.
- The operator which requires a single operand is known as a unary operator (++x).
- The Operator requires two operands is known as binary operator(a+b)
- The Operator requires three operands is called ternary operator.
Types of Operator
- Arithmatic Operator
- Relational Operator
- Assignment OperatoR
- Logical Operator
- Bitwise Operator
- Membership Operator
- Identity Operator
1. Arithmatic Operator
| 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 |

2. Relational Operator
| Operator | Name | 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 |
C. Assignment Operator
| = | x = 5 | x = 5 |
| += | 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 |
| <<= | x <<= 3 | x = x << 3 |

Assignment Operator Vs Relational Operator
4.Logical Operator
Logical operators are used to combine conditional statements:
i) ‘and’ operator
first operand second operand Result
True True True
True False False
False True False
False False False
ii) ‘or’ Operator
first operand second operand Result
True True True
True False True
False True True
False False False
iii) ‘not’ operator-Reverse the result, returns False if the result is true.
5. Bitwise Operator
Bitwise operator are used to perform bitwise calculations. These operators are applicable only for ‘int’ and ‘bool’ type only.These operator are also called binary operator.
AND operator—-return 1 if both bits are 1 otherwise 0
Example—10—-1010
3— 0011
—————————–
1010
&
0011
=====
0010 2(decimal)
=====
OR operator–return 1 if any of the bits is 1.If both the bits are 0 then
========== it return 0
1010
|
0011
=====
1011======11(decimal)
====
XOR operator—-return 1 if bits are different otherwise 0
=============
1010
^
0011
=====
1001 (9 decimal)
====
6. Membership Operator
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 |
7. Identity Operator
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 |
