in Python is associated with a namespace. The code in the Python files are linked to the __main__ namespace, the builtin functions such as the `print()` and the `isinstance()` BIFs are a part of `__builtins__` namespace, but when we create our own custom modules, they're put in a namespace with the same name as the module. Thus, the function needs to be invoked with the name of the namespace (and consequently module) that contains it. So, we use `nester.print_lol()` instead of just `print_lol()`. This is called Namespace Qualification. An important distinction is the use of `from <module> import <functionName>` statements, which remove the necessity for namespace qualifications. However, if there's a function with the same name in the file as well, the imported one will override the local function. """ import nester cast = ['Palin', 'Cleese', 'Idle', 'Jones', 'Gilliam', 'Chapman'] nester.print_lol(cast) """ To share the code with the PyPI community, we used to have to do a commandline registration (telling the command line utilities the login credentials required). The command for this is `python3 setup.py register`. Pre-registration is no longer supported (or required), and hence the files can be directly uploaded with `python3 setup.py sdist upload`. Python, just like java, has the concept of a bytecode file. So, it generates a .pyc file (like a java's .class file) that it can execute directly and skip the compilation as long as the source code doesn't change. However, this is a run-time optimization performed by the python interpreter, and the original .py file is still the one we need the users to have.
