Yes.

I was trying to understand why it worked when written in, but not
An example:
class classA:
def __init__(self):
self.b = 1
def doStuff():
some calcs
a..b = 0
a = classA():
print a.b
doStuff()
print a.b
That works as hoped, printing 1, 0.
But, if I move doStuff to another module and:

I gather that 'with' is on its way to becoming a reserved word. Is

Actually that might help, as all I need the date for is to index
values.
Thanks, I'll give it a spin.
Good morning,
I store time series data in a SQL database. The results of a typical
query using pyodbc look like this.

"2007-01-17" 22.57
Where Date is a datetime.date object and Close is a float.
I'd like to put this data in a NumPy array for processing, but am

There must be a better way to multiply the elements of one list by
another:
a = [1,2,3]
b = [1,2,3]
c = []
for i in range(len(a)):
c.append(a[i]*b[i])
a = c
print a
[1, 4, 9]
Perhaps a list comprehension or is this better addressed by NumPy?
Thanks,

It let's me access lists
That's interesting and I take your point. Maybe there is a better way.
Here is what I am doing now. (working)
I start with a text file of ticker symbols. I read each symbol and
stick it in a list, retrieve the data for it from MySQL, do a trivial
smoothing and pass the data to a modeling routine.

Thanks for your reply.
That seems like an interesting and practical approach. However, I have
one worry. In addition to the config file I am parsing command-line
overrides to the config values via optparse. Many modules, classes and
functions depend on these values, which means a lot of code dupli
For example I have a class named Indicators. If I cut it out and put it
in a file call Ind.py then "from Ind import Indicators" the class can
no longer see my globals. This is true even when the import occurs
after the config file has been read and parsed.
