Share Large, Read-Only Numpy Array Between Multiprocessing Processes
...od reference example. I don't need any kind of locks, since the array (actually a matrix) will be read-only. Now, due to its size, I'd like to avoid a copy. It sounds like the correct method is to create the only copy of the array as a sharedmem array, and then pass it to the Process objects...
Will the base class constructor be automatically called?
... age of customer be 2? It seems like the base class's constructor will be called no matter what. If so, why do we need to call base at the end sometimes?

A new function reference is created after .bind() is called!
See Does bind() change the function reference? | How to set permanently?

Installing the package (in a virtualenv or not) will give you what you want, though I would suggest using pip to do it rather than using setuptools directly (and using setup.cfg to store the metadata)
Using the -m flag and runnin...
Why do we need extern “C”{ #include } in C++?
...
C and C++ are superficially similar, but each compiles into a very different set of code. When you include a header file with a C++ compiler, the compiler is expecting C++ code. If, however, it is a C header, then the compiler expects the data cont...
How to use timeit module
...
The way timeit works is to run setup code once and then make repeated calls to a series of statements. So, if you want to test sorting, some care is required so that one pass at an in-place sort doesn't affect the next pass with already sorted data (that, of course, would make the Timsort reall...
