error: argument after ** must be a dictionary

[abcd]

I have class like this...

import threading
class MyBlah(object):
def __init__(self):
self.makeThread(self.blah, (4,9))

def blah(self, x, y):
print "X and Y:", x, y

def makeThread(self, func, args=(), kwargs={}):
threading.Thread(target=self.blah, args=args,
kwargs=kwargs).start()

When I do...
b = MyBlah()

I am getting this error:
TypeError: MyBlah object argument after ** must be a dictionary

What am I missing?

self.makeThread(self.blah, (4,9))

def blah(self, x, y):
print "X and Y:", x, y

def makeThread(self, func, args=(), kwargs={}):

kwargs=kwargs).start()

When I do...
b = MyBlah()

I am getting this error:
TypeError: MyBlah object argument after ** must be a dictionary

I'm getting

X and Y: 4 9

are you sure you posted the right code ?

where's the rest of the traceback, btw ?

print "X and Y:", x, y

def makeThread(self, func, args=(), kwargs={}):
threading.Thread(target=self.blah, args=args,
kwargs=kwargs).start()

Shouldn't it be:

def makeThread(self, func, *args, **kwargs):
threading.Thread(target=self.blah,
*args,
**kwargs).start()

Shouldn't it be:

def makeThread(self, func, *args, **kwargs):
threading.Thread(target=self.blah,
*args,
**kwargs).start()

No. threading.Thread() doesn't use *args, **kwargs, it uses explicit
named parameters.

Not sure if it matters, but this occurs when running a unittest.

The trace back is:
