Thanks for the explanation of indentation! I kind of understood that, but
wanted to be sure I understood correctly what was happening with the text
file inside the for loop. And if that sounds a little loopy, well... :)

Well this is kind of instructive. Assigning rows = Results and using
Results as an argument to indent() produce the same traceback message. I
was right that the "rows" argument needed the value of "Results", so I *am*
learning something. However, it seems that the function doesn't like the
value I give it.
### Using Results as the argument to indent() ###
Traceback (most recent call last):
File "ekklesia.py", line 165, in ?
Main()

RunMenu(Menu_Main)
File "ekklesia.py", line 31, in RunMenu

File "/home/donp/python/ekklesia/tbl_Tabs.py", line 24, in indent
logicalRows = [rowWrapper(row) for row in rows]
File "/home/donp/python/ekklesia/tbl_Tabs.py", line 21, in rowWrapper
newRows = [wrapfunc(item).split('\n') for item in row]
AttributeError: 'NoneType' object has no attribute 'split'
### end traceback ###
My SQL query functions return a tuple, so indent() has to recognize that
much. I suspected this has to do with the wrapfunc argument. I had dropped
it at some point, thinking that would help me grasp the problem. I fed it
rows(using the rows= Results at the moment), and got this traceback:
### revised function call and traceback ###
mbrPhone.write(indent(rows, hasHeader=False, separateRows=False,
prefix='| ', postfix=' |'))wrapfunc=lambda
x:wrap_onspace(rows, 12))
Traceback (most recent call last):
File "ekklesia.py", line 9, in ?
from ekklesia_db import *
File "/home/donp/python/ekklesia/ekklesia_db.py", line 64
mbrPhone.close()
^
SyntaxError: invalid syntax
### end function call and traceback ###
mbrPhone.close() is properly indented. I even put the whole indent() call
on one single line. So now I'm not sure where to go. I know that error
messages can sometimes be misleading. I also know that close() takes
exactly 0 arguments. So maybe I need to look back at indent()?

I've read the Python tutorial, Alan's tutorial, and have worked through some
of the others as well. It looks simple enough, but when I try things out
for myself, I find it difficult to see how the examples apply in my
situation. Which is why I sought out this list. My Guess is that I need to
"just do it" for a while before it'll come to me.
