I have two lists of strings that, in a better world, would be one list. I need to concatenate the lists, but the last element of the first list needs to be concatenated with the first element of the second list. So these guys: list1 = ["bob", "sal"] list2 = ["ly", "nigel"] needs to become out = ["bob", "sally", "nigel"] So this isn...
Is it possible to do array broadcasting in numpy with parameters that are vectors? For example, I know that I can do this def bernoulli_fraction_to_logodds(fraction): if fraction == 1.0: return inf return log(fraction / (1 - fraction)) bernoulli_fraction_to_logodds = numpy.frompyfunc(bernoulli_fraction_to_logodds, 1, 1)...

I've got a socket from which I'm reading XML data. However, this socket will spit out multiple different XML documents, so I can't simply parse all the output I receive.

I have a question about righteous way of programming in Python... Maybe there can be several different opinions, but here it goes: Let's say I have a class with a couple of private attributes and that I have implemented two getters/setters (not overloading __getattr__ and __setattr__, but in a more “Java-tistic” style): class MyClass: ...

I have two questions: What are the differences between how C++ constructs an object and how Python "cons...

This prevents two threads from being able to corrupt the state of the Python interpreter, but also prevents multiple threads ...
