The __init__.py files are required to make Python treat the directories as containing packages, this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.. __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable. But it sounds like you guys are leaning more towards leaving it as is and making the user explicitly add '' to their sys.path. Absolute vs. A regular package is typically implemented as a directory containing an __init__.py file. This post addresses this issue and proposes a solution. python agent.py and agent.py has a number of imports, including: import checks When a regular package is imported, this __init__.py file is implicitly executed, and the objects it defines are bound to names in the packages namespace.
