Python Operators and Operands – Types of Operators in Python

The following example illustrates the use of the above discussed operators.

>>> a=20
 >>> b=45.0
 >>> a+b
 65.0
 >>> a-b
 -25.0
 >>> a*b
 900.0
 >>> b/a
 2.25
 >>> b%a
 5.0
 >>> a**b
 3.5184372088832e+58
 >>> b//a
 2.0

Python Relational operators

A prelational operator is an operator that tests some kind of relation between two operands. Table enlist the relational operators with description.

The following example illustrates the use of the above discussed operators.

>>> a,b=20,40
>>> a==b
False
>>> a!=b
True
>>> a<>b
True
>>> a>b
False
>>> a<b
True
>>> a>=b
False
>>> a<=b
True

Python Assignment operators

Assignment operator is an operator which is used to bind or rebind names to values. Augmented assignment is the combination, in a single statement, of a binary operation and an assignment statement. An augmented assignment expression like x+=1 can be rewritten as x=x + 1. Table enlist the assignment operators with description.

The following example illustrates the use of the above discussed operators.

>>> a,b=20,40
>>> c=a+b
>>> c
60
>>> a,b=2.0,4.5
>>> c=a+b
>>> c
6.5
>>> c+=a
>>> c
8.5
>>> c-=a
>>> c
6.5
>>> c*=a
>>> c
13.0
>>> c/=a
>>> c
6.5
>>> c%=a
>>> c
0.5
>>> c**=a
>>> c
0.25
>>> c//=a
>>> c
0.0

Python Bitwise operators

A bitwise operator operates on one or more bit patterns or binary numerals at the level of their individual bits. Table enlists the bitwise operators with description.

The following example illustrates the use of the above discussed operators.
>>> a,b=60,13
>>> a & b
12
>>> a | b
61
>>> a^b
49
>>> ~a
-61
>>> a<<2
240
>>> a>>2
15

In the above example, the binary representation of variables a and b are 00111100 and 00001101, respectively. The above binary operations example is tabulated in table.

Python Logical operators

Logical operators compare boolean expressions and return a boolean result. Table enlist the logical operators with description.

The following example illustrates the use of the above discussed operators.

>>> 5>2 and 4<8
True
>>> 5>2 or 4>8
True
>>> not(5>2)
False

Python Membership operators

Membership operator is an operator which test for membership in a sequence, such as string, list, tuple etc. Table enlists the membership operators.

1The following example illustrates the use of the above discussed operators.

>>> 5 in [0,5,10,15]
True
>>> 6 in [0,5,10,15]
False
>>> 5 not in [0,5,10,15]
False
>>> 6 not in [0,5,10,15]
True

Python Identity operators

Identity operators compare the memory locations of two objects. Table provides a list of identity operators including a small explanation.

The following example illustrates the use of the above discussed operators.

>>> a=b=3.1
>>> a is b
True
>>> id(a)
30984528
>>> id(b)
30984528
>>> c,ct=3.1,3.1
>>> c is d
False
>>> id(c)
35058472
>>> id(d)
30984592
>>> c is not d
True
>>> a is not b
False
