python - Accessing variable from another class -

i'm trying use variable 1 class in another, error, "run() missing 1 required positional argument: 'mywindowclass'"

class taskthread(qtcore.qthread):     updateprogresssignal = qtcore.pyqtsignal(int)     def run(self, mywindowclass):         in range(101):            self.updateprogresssignal.emit(i)            print ( mywindowclass.pbtimeupdate )            time.sleep(mywindowclass.pbtimeupdate)   class mywindowclass(qtgui.qdialog ):     def __init__(self, *args):         super(mywindowclass, self).__init__(*args)           self.pbtimeupdate = .2         self.mylongtask = taskthread()         self.mylongtask.updateprogresssignal.connect (self.onprogress)         self.mylongtask.start()      def onprogress (self, val )         print (val) 

i've tried making variable global (declared outside both classes in same file), updating variable value in in 1 class, other class still sees original value)

what issue?

this should work:

class mywindowclass(qtgui.qdialog):     pbtimeupdate = .2  class taskthread(qtcore.qthread):     updateprogresssignal = qtcore.pyqtsignal(int)      def run(self):         in range(101):            self.updateprogresssignal.emit(i)            print(mywindowclass.pbtimeupdate)            time.sleep(mywindowclass.pbtimeupdate)
