Python- Operators
Operators are manage to perform operations on variables and values.
Types of python operators:
- Arithmetic operators
- Assignment operators
- Comparison operators
- Logical operators
- Identity operators
- Membership operators
- Bitwise operators
Python Arithmetic Operators
Arithmetic operators are used to manage common mathematical operations.
|
Operator |
Name |
Example |
Another example |
|
+ |
Addition |
x + y |
5+2 |
|
- |
Subtraction |
x - y |
5-2 |
|
* |
Multiplication |
x * y |
5*2 |
|
/ |
Division |
x / y |
5/2 |
|
% |
Modulus |
x % y |
5%2 |
|
** |
Exponentiation |
x ** y |
5**2 |
|
// |
Floor division |
x // y |
5//2 |
Python Assignment Operators
Assignment operators are manage to assign values to variables.
|
Operator |
Example |
Same As |
|
= |
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 |
Python Comparison Operators
Comparison operators are manage to compare two values.
|
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 |
Python Logical Operators
Logical operator is use 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 |
