I'm trying to call a stored procedure on a multi-db Django installation, but am not having any luck getting results. The stored procedure (which is on the secondary database) always returns an empty array in Django, but the expected result does appear when executed in a mysql client. My view.py file from SomeDBModel import models from django.db import connection def index(request, someid): #Some related django-style query that works here loc = getLocationPath(someid, 1) print(loc) def getLocationPath(id, someval): cursor = connection.cursor() cursor.callproc("SomeDB.spGetLocationPath", [id,

I have a small GUI application that listens for network messages so a user can update some info and accept it. This is in a production factory environment and used for interacting with a specific piece of physical hardware (over serial in some cases). The workflow looks like this: User is interacting with another program (5250 Green Screen) They enter a certain keybinding that sends a UDP message to a Tkinter GUI The Tkinter GUI does a deiconify() User edits data, accepts (Enter) and it does an iconify() My issue is that on windows XP, the GUI does not become active when I do the deiconify and

I wanted to start using pillow, but I ran into some problems: At first, I thought I could simply pip install pillow , so I activated my virtualenv and did exactly that. When it didn't worked, I realized that I need to install some dependencies for pillow ( installation ). I'm on Ubuntu 14.04. But even after I installed those dependencies and reinstalled pillow, the Code didn't work. Until I tried it outside of the virtualenv and pip installed pillow on my main Python3.4 installation, where my Code suddenly worked. import tkinter as tk from PIL import Image, ImageTk def show(img, text=""): root

I'm working with a big dictionary and for some reason I also need to work on small random samples from that dictionary. How can I get this small sample (for example of length 2)? Here is a toy-model: dy={'a':1, 'b':2, 'c':3, 'd':4, 'e':5} I need to perform some task on dy which involves all the entries. Let us say, to simplify, I need to sum together all the values: s=0 for key in dy.key: s=s+dy[key] Now, I also need to perform the same task on a random sample of dy; for that I need a random sample of the keys of dy. The simple solution I can imagine is sam=list(dy.keys())[:1] In that way I
