\mymulticolumn{1}{x{8.4cm}}{An init.py file is a special file that is used to indicate that a directory contains a Python package.

This can be useful for initializing package-level data or performing other tasks \newline % Row Count 8 (+ 8)
Before Python 3.3, an init.py file was required for every package directory. Otherwise, Python would not recognize the directory as a package and would not be able to import modules from it. This was done to prevent directories with common names, such as string, from unintentionally hiding valid modules that occur later on the module search path. \newline % Row Count 15 (+ 7)
However, since Python 3.3, an init.py file is no longer mandatory for defining a package. Python can also recognize namespace packages, which are packages that do not have an init.py file and can span multiple directories. Namespace packages allow multiple portions of a package to be distributed and installed separately, and then merged together at runtime% Row Count 23 (+ 8)
