# Python Operators

### Python Operators A PEMDAS (Parenthesis, Exponential, Multiply, Division, Addition, Subtraction) rule is used for the precedence of operators in Python. Operators having same priority are evaluated from left to right.

1. Python Arithmetic Operator

It is used for mathematical operations such as addition, substraction, multiplication and division etc.

``````x = 10
y = 5
print('x - y =',x-y) #Substraction
print('x * y =',x*y) #Multiplication
print('x / y =',x/y) #Division
print('x // y =',x//y) #Floor Division
print('x ** y =',x**y) #Exponent``````
2. Python Comparison Operators

It is used to compare values between operands.

``````x = 121
y = 101
print('x > y is',x>y) #Greater than
print('x < y is',x= y is',x>=y) #Greater than equal to
print('x <= y is',x<=y) #Less than equal to``````
3. Python Logical Operators
``````x = True
y = False
print('x and y is',x and y) #if both are true
print('x or y is',x or y) #if either one is true
print('not x is',not x) #returns the complement``````
4. Python Bitwise Operators

It is used to manipulate bit values

``````a = 6
b = 3
print ('a=',a,':',bin(a),'b=',b,':',bin(b)) c = 0
c = a & b
print ("result of AND is ", c,':',bin(c))
c = a | b
print ("result of OR is ", c,':',bin(c))
c = a ^ b
print ("result of EXOR is ", c,':',bin(c))
c = ~a
print ("result of COMPLEMENT is ", c,':',bin(c))
c = a << 2
print ("result of LEFT SHIFT is ", c,':',bin(c))
c = a>>2
print ("result of RIGHT SHIFT is ", c,':',bin(c))``````
5. Python Membership Operators

Test for membership in a sequence

``````a = 5
b = 10
list = [1, 2, 3, 4, 5 ]
if ( a in list ):
print ("Line 1 - a is available in the given list")
else:
print ("Line 1 - a is not available in the given list")
if ( b not in list ):
print ("Line 2 - b is not available in the given list")
else:
print ("Line 2 - b is available in the given list")``````
6. Python Identity Operators

It checks if values on either side of equality operator point to the same object.

``````a = 14
b = 14
print ('Line 1','a=',a,':',id(a), 'b=',b,':',id(b))
if ( a is b ):
print ("Line 2 - a and b have same identity")
else:
print ("Line 2 - a and b do not have same identity")``````
