I feel like I'm missing something simple, but I have now spent hours
googling for an answer. I think I must not be searching for the right terms,
or else this is something I'm not supposed to be doing - but it seems
straightforward to me.
Here's my test code (condensed from the actual much longer code I'm adapting
from functions to objects - I'm new to OOP, but I'm trying J ):
___________________________________________
class TestObject:
def __init__(self):
# options and arguments from commandline-->OptionParser
self.opt = ""
self.args = []
def load_cfg(self):
# read+parse commandlnie
self._parse_commandline()
def load_ini(self):
##### I'm trying to get at 'inifile' from the commandline... #####
print self.opt['inifile']
def _parse_commandline(self):
parser = OptionParser()
parser.add_option("-i", dest = "inifile", help = "specify an ini
file to load")
(self.opt, self.args) = parser.parse_args()
if __name__ == '__main__':
# parses command-line argumenmts
from optparse import OptionParser
test = TestObject()
test.load_cfg()
test.load_ini()
___________________________________________
In the middle is a comment with five hashes to show you the crux of my
problem.
If I eliminate "['inifile']", I can print the list.
How in the world can I get just the 'inifile' element?
Ideally, of course, I'm not printing this - I'm going to access it from
outside the class, or even inside the class.
The error I get when running the above code:
Traceback (most recent call last):
File "listinclass.py", line 34, in <module>
test.load_ini()
File "listinclass.py", line 17, in load_ini
print self.opt['inifile']
AttributeError: Values instance has no attribute '__getitem__'
I've googled for "list in a class" and pretty much every variant I can think
of, and I just can't seem to find a single example of someone trying to get
to an element of a list stored in a class. so I apologize for asking a
basic/simple question, but I just can't find it.
Many thanks for your consideration.
