Operators in Python [Part-3]

Membership operators: This operators are used to test if a value or variable is present in a sequence (string, list, tuple, set and dictionary). Assume two variable x and y, then:

Operator	Description	Example
in	True if value or variable is present in the sequence	x in y
not in	True if value or variable is not present in the sequence	x not in y

Example -

my=["Neoogy","Google","Whatsapp","Facebook"]
print("Neoogy" in my) # returns True because the value "Neoogy" is in the sequence (list)
print("Twitter" not in my) # returns True because the value "Twitter" is not in the sequence (list)

Output will be

True
True

Bitwise operators: The following table shows the bitwise operators used in Python 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
<<	Left shift	The left operands value is moved left by the number of bits specified by the right operand.
>>	Right shift	The left operands value is moved right by the number of bits specified by the right operand.

Example -

a=20 # In binary 10 = 0001 0100
b=10 # In binary 13 = 0000 1010
c=a&b
print(c) #0000 0000 which is 0
d=a|b
print(d) #0001 1110 which is 30 in decimal
e=a^b
print(e) #0001 1110 which is 30 in decimal
f=~b
print(f) #1111 0101 which is -11 in decimal
g=a<<3
print(g) # 1010 0000 which is 160 in decimal
h=b>>3
print(h) #0000 0001 which is 1 in decimal

Output will be

0
30
30
-11
160
1
