[Tutor] shelves behaving badly

i've implemented a database as a shelve of record class instances. some of the fields in each record are dictionaries. i needed to parse info from 3 different reports into the dictionary fields in each record instance. i wrote the code to do this and tinkered it to fit the different reports (i.e.

[Tutor] database question

I've created a database as a shelve, where each value in the shelve file is a record class instance that has attributes representing fields. Let's say I enter 300 records in the shelve, then I decide to add a field to future records, or remove a field from future records. How can I update the exis

[Tutor] define vars by iteration

I've got a bunch of pickled class instances with self.name attributes, and I would like to assign the instances themselves to variables named whatever is stored in self.name using a function. "Can't assign to literal", right? Is there a way to do this?   Thanks,   Luke

[Tutor] Assign to vars by iteration

[Tutor] dictionaries in classes

Hi,   Another stumped beginner here.   I'm trying to have functions to create, edit and store dictionaries within a class. What I can't figure out is how to retain the edits after making them. I think it has something to do with namespace. Ideally I'd like to pickle class instances and be able to a

[Tutor] Sum of List Elements

Hi All, I have spent an embarrassingly large amount of time trying to solve what on its face seems like a simple problem. I have a list of intergers, and I want to assign the sum of the intergers in the list to a variable. There are only intergers in the list. The best I have been able to do so

[Tutor] Filtering Spreadsheet Data

Hi All, I have several frighteningly cumbersome reports to review at my new job. I would like to write a python program to help me with my analysis. The goal of the program is to filter out information that doesn't meet certain requirements and print relevant results back to a legible report that

[Tutor] "Dispatching" functions with args

Hi! I am using a suggestion from this list to handle calling different functions conditionallly based on user input. What I'm trying to do is have functions that are 'configurable' in the sense that a choice from the user affects the way it performs. This works: def aFunc(): print "a

Hi! My questions arose from reading the "Help with Classes" email that's been on this list for the past couple of days. I'm also writing a text game, but mine is puzzle not adventure. Anyway, someone mentioned that you can key words to a dictionary to have user input run functions. I am looking

[Tutor] Functions Calling Functions

Hi - I'm working on a command-line game. Is there anything wrong with having each 'chapter' of the game be a function that links to other chapters by calling them? I only ask because when a recent traceback returned about 40 lines worth of error message, I realized that the functions are all bein
