Is there a difference between and is

Question

In Python, are the following two tests for equality equivalent?

n = 5
# Test one.
if n == 5:
    print 'Yay!'

# Test two.
if n is 5:
    print 'Yay!'

Does this hold true for objects where you would be comparing instances (a list say)?

Answer 1

In Python == operator is used for equality and comparison, 
and also the is operator is used to show the similarity.

Let us take an example:

num1 = 20
num2 = 20
num1 == num2

Output

True

num1 is num2

Output

True

num1 == num2 means num1 is num2
