I was testing a web service in PHP and Python. The address of the web service was, let's say, http://my.domain.com/my/webservice. When I tested the web service in PHP using that URL everything worked fine. But, when I used the same location but in Python using SOAPpy I got an error.

Suppose that I have class C. I can write o = C() to create an instance of C and assign it to o. However, what if I want to assign the class itself into a variable and then instantiate it? For example, suppose that I have two classes, such as C1 and C2, and I want to do something like: if (something): classToUse = C1 else: class...
When hovering over a data point in Chaco, I would like a small text box to appear, with the text I desire. Also, when I click on a data point (or close enough), I would like my program to take a certain action. I have seen relevant parts of the Chaco documentation, but implementing them has proved difficult. Any help would be appreciated...

The question is not the same as What’s the best way to generate a UML diagram from Python source code?, but the other way around. Topcoder UML tool automatically generates code in only Java or C#. Since I need to create a very depended data structure at a point, I am hesitant to turn to Java. I want to use Python. So: Is there an UML-...
In other Python IDEs (PythonWin and Idle) it's possible to hit a key and have your current source file window reloaded into the console. I find this useful when experimenting with a piece of code; you can call functions from the console interactively and inspect data structures there. Is there a way to do this with Eclipse/Pydev? So f...
