The identity operator in Python

This article mainly introduces the identification operators in Python, is the basic knowledge of Python learning, need friends can refer to the

The following table lists the identity operators that are supported by all Python languages.

Example:

Try the following examples to understand the identity operators provided by all the Python programming languages:

#!/usr/bin/python A = b = ' if (A is B): print ' line 1-a and B have same identity ' else:print ' line 1-a and b does 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 = More 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 does not have same identity ' else:print ' Line 4-a and B have same identity "

When the above program is executed it produces the following results:

Line 1-a and B have same identity line 2-a and B have same identity line 3-a and B does not have same identity line 4 -A and B do not have same identity
