How to check if variable is a specific class in python?

Question

I have a variable “myvar” that when I print out its
type(myvar)

the output is:

<class 'my.object.kind'>

If I have a list of 10 variables including strings and variables of that kind.. how can I construct an if statement to check whether an object in the list “mylist” is of <type 'my.object.kind'>?

Answer 1

Use isinstance, this will return true even if it is an instance of the subclass:

if isinstance(x, my.object.kind)

Or:

type(x) == my.object.kind #3.x

If you want to test all in the list:

if any(isinstance(x, my.object.kind) for x in alist)

if any(map(lambda x: isinstance(x, my.object.kind), my_list_of_objects)):
    print "Found one!"

Try
