Pythonisinstance determines the object type

In Python, the method for determining the object type is very simple. you do not need to use the following method as in other languages. The code is as follows:

If (typeof (objA) = typeof (String ))
{
// TODO
}

In Python, you only need to use the built-in function isinstance, which is very simple to use, for example, the following example:

The code is as follows:

Class objA:
Pass

A = objA ()
B = 'a', 'V'
C = 'a string'

Print isinstance (A, objA)
Print isinstance (B, tuple)
Print isinstance (C, basestring)

Output result:
True
True
True
