Hi, I'm trying to learn Python programming and I ran into an odd =
problem.
I was reading the sample chapter of "Python and Tkinter programming" to =
learn how to use Tkinter in Python.
I downloaded the sample code and tried to run them in IDLE.=20
For some reason, I couldn't run them in IDLE with the following error.
Traceback (innermost last)
File "c:\yjlee\worx\dissertation\python-related\python and tkinter =
programming\grayson\examples\chapter11\plot.py", line 404, in ?
graph.draw(graphObject, 'automatic', 'automatic')
File "c:\yjlee\worx\dissertation\python-related\python and tkinter =
programming\grayson\examples\chapter11\plot.py", line 226, in draw
xticks =3D self._ticks(xaxis[0], xaxis[1])
File "c:\yjlee\worx\dissertation\python-related\python and tkinter =
programming\grayson\examples\chapter11\plot.py", line 363, in _ticks
ticks.append(t, format % (t,))
TypeError: append() takes exactly 1 argument (2 given)
Program disconnected.
The example seems to provide wrong number of argument and I wanted to =
look up the append() method of Python List. But I don't know where I to =
look up. Is there on-line document for all the methods in Python?
According to the error message, the example code was wrong, but it is =
hard to believe. I think a lot of people already read this article and =
if so, it should have been updated a long time ago, shouldn't it?
Thanks.=20
