call a variable created in an event function in wx python -

-

i created variable (snowdir) via getpath inside wx.dirdialog box , use snowdir outside function. there sample of code:

for file in os.listdir(snowdir):             if fnmatch.fnmatch(file, '*.hdf'):                  if file[9:16] == a:                      inputhdf =  (snowdir + '\\' + file)                      print 'input hdf is: ', inputhdf                     tmod = 1  def ondownload(self, e):     modispathfile = 'modis_data_directory_path.txt'     dlg = wx.dirdialog(self, "choose directory:",                        style=wx.dd_default_style                        #| wx.dd_dir_must_exist                        #| wx.dd_change_dir                        )      if dlg.showmodal() == wx.id_ok:         print "you chose %s" % dlg.getpath()         snowdir = dlg.getpath()         print 'snowdir : ', snowdir         dlg.destroy()  more code ....  return snowdir

any appreciated since i've search net without lock , i'm getting out of time.

just assign self.snowdir , can access object , has access it! e.g.:

def ondownload(self, e):     modispathfile = 'modis_data_directory_path.txt'     dlg = wx.dirdialog(self, "choose directory:",                        style=wx.dd_default_style                        #| wx.dd_dir_must_exist                        #| wx.dd_change_dir                        )      if dlg.showmodal() == wx.id_ok:         print "you chose %s" % dlg.getpath()         self.snowdir = dlg.getpath()         print 'snowdir : ', self.snowdir         dlg.destroy()

in same scope - i.e. part of same object:

def ondoitclick(self, event):     """ action uses snowdir """     self.mod01_dir = os.path.join(self.snowdir,'mod01')     ....

outside scope: *assuming above code part of class definition of *myframeclass and app uses theframe = myframeclass(...) at same level above can use:

if hasattr(theframe, snowdir):    print 'snowdir', theframe.snowdir else:    print 'user did not set snowdir'
