Operators in Python

Arithmetic Operator

• +     -    *    /    %    //

 #program for Airthmetic operator

 >>> a=10
 >>> b=3
 >>> a+b        #addition
 13
 >>> a-b        #subtraction
 7
 >>> a*b        #multiplication
 30
 >>> a/b        #division, result will be float value
 3.3333333333333335
 >>> a//b       #floor, result will be integer
 3
 >>> a%b        #modulus
 1
 >>> 

Relational Operator

• >    >=    <    <=    ==    !=

 #program for Relational operator

 >>> a = 10
 >>> b = 3
 >>> a > b
 True
 >>> a >= b
 True
 >>> a < b
 False
 >>> a <= b
 False
 >>> a == b
 False
 >>> a != b
 True

Logical Operator

• and    or    not

 #program for Logical operator

 >>> a = 10
 >>> b = 3
 >>> a and b
 3
 >>> a or b
 10
 >>> not a
 False
 >>> not b
 False
 >>> not True
 False
 >>> not False
 True

Assignment Operator

• =

 #program for Assignment operator

 >>> a = 10
 >>> b = 3

Short-Hand Assignment operator

• +=    -=    *=    /=    %=    //=    >>=    <<=    **=    &=    |=    ^=

 #program for Assignment operator

 >>> a = 10
 >>> a += 1
 >>> a
 11
 >>> a -= 2
 >>> a
 9
 >>> a *= 5
 >>> a
 45
 >>> a //= 9
 >>> a
 5
 >>> a >>= 1
 >>> a
 2
 >>> a <<= 1
 >>> a
 4
 >>> a **= 2
 >>> a
 16
 >>> a &= 2
 >>> a
 0
 >>> a |= 16
 >>> a
 16
 >>> a ^= 2
 >>> a
 18
 >>> a /= 3
 >>> a
 6.0

Bit-wise Operator

• &    |    ^    <<    >>

 #program for Bit-wise operator

 >>> a =10
 >>> b = 3
 >>> a & b
 2
 >>> a | b
 11
 >>> a ^ b
 9
 >>> a << 2
 40
 >>> b >> 2
 0

Membership Operator

• in    not in

 #program for Menbership operator

 >> > a = "Mandeep Singh"
 >> > b = "Singh"
 >> > a in b
 False
 >> > b in a
 True
 >> > a not in b
 True
 >> > b not in a
