Python Identity Operators Example

There are used to compare the memory locations of two operators.

Example:

#!/usr/bin/python

a = 20
b = 20

if ( a is b ):
print “Line 1 – a and b have same identity”
else:
print “Line 1 – a and b do not have same identity”

if ( id(a) == id(b) ):
print “Line 2 – a and b have same identity”
else:
print “Line 2 – a and b do not have same identity”

b = 30
if ( a is b ):
print “Line 3 – a and b have same identity”
else:
print “Line 3 – a and b do not have same identity”

if ( a is not b ):
print “Line 4 – a and b do not have same identity”
else:
print “Line 4 – a and b have same identity”

Output:

Line 1 – a and b have same identity
Line 2 – a and b have same identity
Line 3 – a and b do not have same identity
