Question

I have this variable on the beginning of the code:

enterActive = False

and then, in the end of it, I have this part:

def onKeyboardEvent(event):
    if event.KeyID == 113: # F2
        doLogin()
        enterActive = True
    if event.KeyID == 13:  # ENTER     
        if enterActive == True:
            m_lclick()        
    return True

hookManager.KeyDown = onKeyboardEvent
hookManager.HookKeyboard()
pythoncom.PumpMessages()

and I get this error when I press enter first, and when I press F2 first:

UnboundLocalError: local variable 'enterActive' referenced before assignment

I know why this happens, but I don’t know how can I solve it…

anyone?

Answer 1

See Global variables in Python. Inside onKeyboardEvent, enterActive currently refers to a local variable, not the (global) variable you have defined outside the function. You need to put

global enterActive

at the beginning of the function to make enterActive refer to the global variable.
