# Python Operators

## Python Operators

Operators are used to perform operations on variables and values.

Python divides the operators in the following groups:

• Arithmetic operators
• Assignment operators
• Comparison operators
• Logical operators
• Identity operators
• Membership operators
• Bitwise operators

## Python Arithmetic Operators

Arithmetic operators are used with numeric values to perform common mathematical operations:

Operator Name Example Try it
+ Addition x + y Try it »
- Subtraction x - y Try it »
* Multiplication x * y Try it »
/ Division x / y Try it »
% Modulus x % y Try it »
** Exponentiation x ** y Try it »
// Floor division x // y Try it »

## Python Assignment Operators

Assignment operators are used to assign values to variables:

Operator Example Same As Try it
= x = 5 x = 5 Try it »
+= x += 3 x = x + 3 Try it »
-= x -= 3 x = x - 3 Try it »
*= x *= 3 x = x * 3 Try it »
/= x /= 3 x = x / 3 Try it »
%= x %= 3 x = x % 3 Try it »
//= x //= 3 x = x // 3 Try it »
**= x **= 3 x = x ** 3 Try it »
&= x &= 3 x = x & 3 Try it »
|= x |= 3 x = x | 3 Try it »
^= x ^= 3 x = x ^ 3 Try it »
>>= x >>= 3 x = x >> 3 Try it »
<<= x <<= 3 x = x << 3 Try it »

## Python Comparison Operators

Comparison operators are used to compare two values:

Operator Name Example Try it
== Equal x == y Try it »
!= Not equal x != y Try it »
> Greater than x > y Try it »
< Less than x < y Try it »
>= Greater than or equal to x >= y Try it »
<= Less than or equal to x <= y Try it »

## Python Logical Operators

Logical operators are used to combine conditional statements:

Operator Description Example Try it
and  Returns True if both statements are true x < 5 and  x < 10 Try it »
or Returns True if one of the statements is true x < 5 or x < 4 Try it »
not Reverse the result, returns False if the result is true not(x < 5 and x < 10) Try it »

## 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 Try it
is  Returns true if both variables are the same object x is y Try it »
is not Returns true if both variables are not the same object x is not y Try it »

## Python Membership Operators

Membership operators are used to test if a sequence is presented in an object:

Operator Description Example Try it
in  Returns True if a sequence with the specified value is present in the object x in y Try it »
not in Returns True if a sequence with the specified value is not present in the object x not in y Try it »

## 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

## Exercise:

Multiply `10` with `5`, and print the result.

```print(10  5)
```
