Special Operators

Python language offers following 2 special operators.

We can use identity operators for address comparison.
There are 2 identity operators are available
- is
- is not
r1 is r2 returns True if both r1 and r2 are pointing to the same object.
r1 is not r2 returns True if both r1 and r2 are not pointing to the same object.

a=10
b=10 
print(a is b) ==> True 

x=True
y=True 
print( x is y) ==> True

x = 'Waytoeasylearn'
y = 'Waytoeasylearn'
a = [10,20,30]
b = [10,20,30]

print(x is y) ==> True

# Output: False
print(a is b) ==> False

Note

We can use is operator for address comparison where as == operator for content comparison.

We can use Membership operators to check whether the given object present in the given collection. (It may be String, List, Set, Tuple OR Dict)
In ==> Returns True if the given object present in the specified Collection
not in ==> Returns True if the given object not present in the specified Collection.

E.g

x="Waytoeasylearn" 
print('e' in x) True 
print('d' in x) False 
print('d' not in x) True 
print('learn' in x) True
