kwargs to python instance method -

i need pass kwargs python instance method following error below.

class test(object):      def __init__(self):         print 'initializaed'      def testmethod(self,**kwargs):         each in kwargs:             print each    x = test() x.testmethod({"name":"mike","age":200})             

error:

traceback (most recent call last):   file "c:\users\an\workspace\scratch\scratch\test.py", line 20, in <module>     x.testmethod({"name":"mike","age":200})             typeerror: testmethod() takes 1 argument (2 given) 

x.testmethod({"name":"mike","age":200})     

this invokes testmethod() 2 positional arguments - 1 implicit (the object instance, i.e. self) , other 1 dictionary gave it.

to pass in keyword arguments, use ** operator unpacking dictionary key=value pairs, this:

x.testmethod(**{"name":"mike","age":200})   

this translates x.testmethod(name='mike', age=200) want. can read argument unpacking in documentation.
