Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python24\lib\lib-tk\Tkinter.py", line 1345, in __call__
return self.func(*args)
TypeError: <lambda>() takes exactly 1 argument (0 given)
I got this error when trying to send command = lambda x: self.adddigit('1')
to makeButton - and for all of the
rest of the digits, too. The way I fixed it was to again put *x in from of
the x in lambda - but I left it out in the key binding.
The reason it needs that is because the key binding sends a Tkinter
instance, event, to the second argument whereas
the button command does not. So to allow for both of them to use the same
adddigit function I had to let the lambda in
the buttons to accept extra junk. I think.
I also took out the list self.bl due to the fact that I am no longer using
the list of lambdas in more than one place.
(I'm not sure I was before either)
Oh,
I get your
whitespace
and readibility
thing
too. *grin*
Here's the code again.
