Why are the commands to change the window position before and after sleep(3.00) being ignored? if self.selectedM.get() == 'Bump': W1 = GetSystemMetrics(1) + 200 print W1 w1.wm_geometry("+100+" + str(W1)) w2.wm_geometry("+100+" + str(W1)) w3.wm_geometry("+100+" + str(W1)) w4.wm_geometry("+1...
I have an application (CLI) which includes the feature of editing account information. It does this by asking a question and putting in the old value in the answer so that it is editable. Currently I'm using the readline module to do this. I'd like another way of doing the same thing that avoids this module (I want to allow the app to ru...
I'm using os.statvfs to find out the free space available on a volume -- in addition to querying free space for a particular path, I'd like to be able to iterate over all volumes. I'm working on Linux at the moment, but ideally would like something which returns ["/", "/boot", "home"] on Linux and ["C:\", "D:\"] on Windows. ...

I have a set of unique vectors (10k's worth). And I need to, for any chosen column, extract the set of values that are seen in that column, in rows where all the others columns are given values. I'm hoping for a solution that is sub linear (wrt the item count) in time and at most linear (wrt the total size of all the items) in space, pr...

While the languages F# and IronPython are technically dissimilar, there is large overlap between their potential uses in my opinion. When is one more applicable than the other? So far it look to me like F# is computationally more efficient while IronPython inherits a better library from Python. I am happy to be corrected. There is a so...
I have a python datetime object which I would like to convert to UTC. I am planning to output it in RFC 2822 format to put in an HTTP header, but I am not sure if that matters for this question. I found some information on this site about converting time objects, and it looks simpler that way, but this time I really want to use datetime ...
I'm new to Google Apps and I've been messing around with the hello world app that is listed on the google app site. Once I finished the app, I decided to try to expand on it. The first thing I added was a feature to allow the filtering of the guestbook posts by the user that submitted them. All I have changed/added is simply a handle...
On the surface, this is pretty simple, and I could implement it myself easily. Just successively call dirname() to go up each level in the file's path and check each one to see if it's the directory we're checking for. But symlinks throw the whole thing into chaos. Any directory along the path of either the file or directory being che...

Obviously, there are core functionalities like being able to connect to a server and join a channel but what are some good functionalities that are usually included in the b...
Python docs say that * and / have the same precedence. I know that expressions in python are evaluated from left to right. Can i rely in that and assume that j*j/m is always equal to (j*j)/m avoiding the parentheses? If this is the case can i assume that this holds for operators with the same precedence in general? ps: The question a...
Is it possible to add an additional condition to join statement created by django ORM? What I need in SQL is 'SELECT "post"."id", COUNT("watchlist"."id") FROM "post" LEFT OUTER JOIN "watchlist" ON ("post"."id" = "watchlist"."post_id" AND "watchlist"."user_id" = 1) WHERE "post"."id" = 123 GROUP BY … In django most of this is...
I have a VPS that's hosting multiple virtual hosts. Each host has it's own access.log and error.log. Currently, there's no log rotation setup, though, this may change. Basically, I want to parse these logs to monitor bandwidth and collect stats. My idea was to write a parser and save the information to a small sqlite database. The scri...
