With the small font size and lots of blank lines I find this hard to read!

When I look at the optparse documentation I guess you want
print self.opt.inifile

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…
