Hi  am tryin to find if another variable, called EVENTHANDLEr exits 
in a file caled pixit.py.

pixit.py looks like:

EVENTHANDLER = {}
print EVENTHANDLER 

The following is the script I am test trying, but it always print 
None. wWhat gives? Any suggestion? Or is ther another way?

guiCb = CtfGui(None)
pixitObj = None

EventHandler = None

def setPixit(value):
    global pixitObj
    global guiCb  # setting value of guiCb 
    global EventHandler  
    pixitObj = value
    guiCb.pixitObj = value # copy value
    print "where are you?"
    try:
       EventHandler = guiCb.pixitObj.EventHandler
       print EventHandler
    except:
       pass   

exec("import pixit")
exec("reload(pixit)")
setPixit(pixit)

if EventHandler != None:
   print "Hi"
else:
   print EventHandler
