- Anyone who wants a brief introduction to Python and the key components of its data science stack, and - Python programmers who want a quick refresher on using Python for data analysis. We do not expect any of our readers to have a formal background in computer science, although some familiarity with programming would be nice to have.
Due to Python’s Global Interpreter Lock, local threads provide parallelism only when the computation is primarily non-Python code, which is the case for Pandas DataFrame, Numpy arrays or other Python/C/C++ based projects. Local process A multiprocessing scheduler leverages Python’s concurrent.futures.ProcessPoolExecutor to execute computations.
