IT sounds like your try/except is masking the error.
Its usually a good idea to NOT Use try/except when developing your
code, then go back and put it in when
OR tests for the truth of the first thing then the truth of the second.
The first part of your OR is always true, so it doesn't test the second.

digits or a slash and some more digits.

Hey there,
i have a simple app that plots some numbers sent by a field sensor with
respect to time. i am trying to do this in pychart, but the problem is,
when the numbers come in, they do so at almost random times.
y shows the value sent by the sensor
x plots the time that the value came in.
Hi Negroup,
First off, you may want to use os.path.join to create paths -
path = 'categories/%s' % self.name
could be -
path = os.path.join(categories, self.name)
This will ensure minimum hassle if you ever want to use this across
multiple OS.
Also, it looks a little tidier, and IMAO,
Erk, I of course meant -
path = os.path.join('categories', self.name)

Then delete a certain card or cards, based upon the user's choice?.

#start of program
The book, Programming Python, shows an example of os.chdir() on the
Windows platform, as follows:
os.chdir(r'c:\temp')
What's the 'r' for? It didn't seem to make any difference in how
Python works - at least not on the surface.
Thanks,
Don
