Python Operators
Python operators are used to perform operations on variables and values.
Python operators are as follow:
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical operators
- Identity operators
- Membership operators
- Bitwise operators
Arithmetic operators
Operator | Name | Example |
+ | Addition | 2 + 2 |
– | Subtraction | 2 – 2 |
* | Multiplication | 2 * 2 |
/ | Division | 2 / 2 |
% | Modulus | 5 % 2 |
** | Exponentiation | 2 ** 2 |
// | Floor division | 2 // 2 |
Python Assignment Operators
Assignment operators are used to assign values to variables
Operator | Example | Same As |
= | x = 2 | x = 2 |
+= | x += 2 | x = x + 2 |
-= | x -= 2 | x = x – 2 |
*= | x *= 2 | x = x * 2 |
/= | x /= 2 | x = x / 2 |
%= | x %= 2 | x = x % 2 |
//= | x //= 2 | x = x // 2 |
**= | x **= 2 | x = x ** 2 |
&= | x &= 2 | x = x & 2 |
|= | x |= 2 | x = x | 2 |
^= | x ^= 2 | x = x ^ 2 |
>>= | x >>= 2 | x = x >> 2 |
<<= | x <<= 2 | x = x << 2 |
Python Comparison Operators
Comparison operators are used to compare two values
Operator | Name | Example |
== | Equal | 2 == 2 |
!= | Not equal | 2 != 3 |
> | Greater than | 2 > 1 |
< | Less than | 2 < 3 |
>= | Greater than or equal to | 2 >= 3 |
<= | Less than or equal to | 2 <= 1 |
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 |
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 |
