Python operators explained

The

operators are used to perform operations on variables and values. Python has the following operators:

arithmetic operators

x = 5

y = 2

print(x+y)

o/p = 7

Print (x - y)

o/p = 3

Print (x * y)

o/p = 10

Print (x/y)

o/p = 2.5

Print (x%y)

o/p = 1

Print the power of (x ** 2) operation

o/p = 25

print ( x // 2) performs integer division

o/p = 2

comparison operator

Print (x > y)

o/p = true

Print (x

o/p = false

Print (x >= y)

o/p = true

Print (x

o/p = false

Print (x==y)

o/p = false

Print (x!=y)

o/p = true

Logical operators

x = true

y = false

Print (x or y)

o/p = true

Print (x and y)

o/p = false

Print (not x)

o/p = false

Print (not y)

o/p = true

Bitwise operators

They handle binary values

x = 2

y = 3

Print (x & y)

o/p = 2

Binary 2 = 010

Binary 3 = 011

Bitwise operation on 010 and 011 gives 010 (decimal 2)

Print (x | y)

o/p = 3

Bitwise OR of 010 and 011 gives 011 (decimal 3)

Print (x >> 2)

o/p = 0

Print(y

o/p = 24

print (~x) # 1’s complement

o/p = -3

assignment operator

a = 3

Print (1)

o/p = 3

a += 3

o/p = 6

a =- 3

o/p = 3

a *= 3

o/p = 9

a &= 3

a++ and ++a do not exist in Python. Using it will produce a syntax error.

identity operator

Check if 2 variables are in the same memory location.

a = 3

b = 3

Print (a is b)

o/p = true

a = [1,2,3]

b = [1,2,3]

Print (a is b)

o/p = false

Print (a is not b)

o/p = true

Member operator

x="Delhi"

Print ("D" in x)

o/p = true

Print ("D" is not in x)

o/p = false

x = [1,2,3]

Print (5 inches x)

o/p = false
