Python Arithmetic Operators

Addition
 
9 + 2
 
>> 11
Subtra­ction
 
9 - 2
 
>> 7
Multip­lic­ation
 
9 * 2
 
>> 18
Division
 
9 / 2
 
>> 4.5
Modulus
 
9 % 2
 
>> 1
Expone­nti­ation
 
3 ** 2
 
>> 81
Floor division
 
9 // 2
 
>> 4

Python Assignment Operators

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

Python Comparison Operators

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
 

Boolean Values

In progra­mming you often need to know if an expression is 
True
or 
False
.
You can evaluate any expression in Python, and get the answer.
 
print(5 < 8)
 
 >>> True
 
print(5 > 8)
 
 >>> False

Python Logical Operators

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

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

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

&
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
