Static methods inherited from builtins.Exception: __new__(*args, **kwargs) from builtins.type Create and return a new object.  See help(type) for accurate signature.

Functions
		convert_size_to_display(size_bytes: float) -> str This function convert size in bytes to human readable presentation.   Ref: "Better way to convert file sizes in Python" https://stackoverflow.com/a/14822210/13441 drive_normcase(path) Norm case for drive letter. Note this is not the same as `normcase()` for path. format_seconds(seconds: float) -> str seconds = int(diff.total_seconds()); is_program_interrupted_by_user() Ref: https://stackoverflow.com/questions/24072790/detect-key-press-in-python pause(pause_duration=30) Pause with support of interruption by user   pause_duration - duration of pause, seconds. Returns:     True if pause worked fine     False if program interruped   Ref: https://wiki.python.org/moin/ForLoop Ref: https://stackoverflow.com/questions/44834493/a-single-python-loop-from-zero-to-n-to-zero rel_file_path(work_file_name, base_file_name, return_absolute_path=False) Note, last part after slash in input file names are considered as file name, not a folder   if return_absolute_path == False     then returns file with path for `work_file_name` relative to `base_file_name`.     In other words this function show how to traverse from one file to other.     Note, if `work_file_name` and `base_file_name` point to different disks then relative path can't be returned, so absolute path returned.   if return_absolute_path == True     then returns absolute path for `work_file_name`     if `work_file_name` is relative than it is considered as relative to `base_file_name`,     and function return absolute path accounting this.     if `work_file_name` is absolute than it is returned.   Ref: https://stackoverflow.com/questions/10149263/extract-a-part-of-the-filepath-a-directory-in-python Ref: https://stackoverflow.com/a/7288073/13441
