Python: is the current directory automatically included in path? -

python 3.4: reading other questions seems if modulename.py file outside of current directory, if want import must add together path sys.path.insert(0, '/path/to/application/app/folder'), otherwise import moduelname statement results in error:

importerror: no module named modulename

does imply python automatically adds other .py files in same directory path? what's going on underneath surface allows import local files without appending python's path? , __init__.py file under surface?

python adds directory initial script resides first item sys.path:

as initialized upon programme startup, first item of list, path[0], directory containing script used invoke python interpreter. if script directory not available (e.g. if interpreter invoked interactively or if script read standard input), path[0] empty string, directs python search modules in current directory first. notice script directory inserted before entries inserted result of pythonpath.

so goes on underneath surface python appends (or rather, prepends) 'local' directory sys.path for you.

this means directory script lives in first port of phone call when searching module.

__init__.py has nil this. __init__.py needed create directory (regular) package; such directory found on python module search path treated module.
