Do I need a custom validator? Do I need a custom widget? If this helps to clear the problem, the relationship is between member and language where a member can have multiple languages and a language is spoken by multiple members. I would like to add a multi-select box in the "add member" form (that I generate using SQLFORM). Thanks :)...
I would like to index a list with another list like this L = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'] Idx = [0, 3, 7] T = L[ Idx ] and T should end up being a list containing ['a', 'd', 'h']. Is there a better way than T = [] for i in Idx: T.append(L[i]) print T # Gives result ['a', 'd', 'h'] ...
Hi, If i have a dictonary in python, will .keys and .values return the corresponding elements in the same order? E.g. foo = {'foobar' : 1, 'foobar2' : 4, 'kittty' : 34743} For the keys it returns: >>> foo.keys() ['foobar2', 'foobar', 'kittty'] Now will foo.values() return the elements always in the same order as their correspondi...

Hi, I have a text file which a lot of random occurrences of the string @STRING_A, and I would be interested in writing a short script which removes only some of them.

I'm trying to use python to sftp a file, and the code works great in the interactive shell -- even pasting it in all at once. When I try to import the file (just to compile it), the code hangs with no exceptions or obvious errors. How do I get the code to compile, or does someone have working code that accomplishes sftp by some othe...
I'm looking for a way to call a python script from a batch file and getting a return code from the python script. Confusing I know, but it's based on a system that's currently in use. I'd re-write it, but this way would be much, much quicker. So: Bat ---------------------> Python * call python file * Bat <----------------------...
For example, str = "hello" str[1::3] And where can I find this in Python documentation? ...
I'm looking for an ORM that allows me to do bulk inserts, as well as create code based on python classes. I tried sqlobject, it worked fine for creating the tables but inserting was unacceptibly slow for the amount of data I wanted to insert. If such an ORM doesn't exist any pointers on classes that can help with things like sanitizing i...

Im fine with the scroll area not having its mouse wheel scrolling functionality, I just need those wheelEvents to call my handler.

I am trying to split up a large xml file into smaller chunks. I write to the output file and then check its size to see if its passed a threshold, but I dont think the getsize() method is working as expected. What would be a good way to get the filesize of a file that is changing in size. Ive done something like this... import string ...
I wonder if Perl, Python, or Ruby can be used to write a program so that it will look for 0x12345678 in the memory of another process (probably the heap, for both data and code data) and then if it is found, change it to 0x00000000? It is something similar to Cheat Engine, which can do something like that on Windows. ...
I'm developing a 'TreeDict' class in Python. This is a basically a dict that allows you to retrieve its key-value pairs in sorted order, just like the Treemap collection class in Java. I've implemented some functionality based on the way unique indexes in relational databases can be used, e.g. functions to let you retrieve values corre...
I have a tuple containing lists and more tuples. I need to convert it to nested lists with the same structure. For example, I want to convert (1,2,[3,(4,5)]) to [1,2,[3,[4,5]]]. How do I do this (in Python)? ...

Hi folks, I have an array with a set of elements. I'd like to bring a given element to the front but otherwise leave the order unchanged. Do folks have suggestions as to the cleanest syntax for this? This is the best I've been able to come up with, but it seems like bad form to have an N log N operation when an N operation could do. ...
