Hi, My name Quentin, and this is my first post to this list so please redirect me if this is not the proper audience.
I have been studying the 'importlib' standard library package this past week, and although I find it very readable I am puzzled by some questions that I'd like to share. - [Chicken and egg] Does the 'import' statement in Python make use of 'importlib'? If so, how are the imports in 'importlib' itself carried out? (for example in __init__.py) - Why does 'importlib' use 'nt' or 'psoix' (see '_bootstrap_external._setup()') rather than the portable 'os', and reimplement some of the latter's functionality, for example '_path_join', or '_path_split'. Another example is in 'SourceFileLoader.set_data()' where the logic of 'os.mkdirs' is reproduced to create all necessary intermediary directories in a file path. - Similarly, would not using the 'struct' module simplify the packing/unpacking of bytecode. For example by defining BYTECODE_HEADER_FMT = '4sII' (Python 3.6) Thanks for any insights you may share and have a nice sunday, Quentin _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
