Python : How to access file from different directory

Question

I have the following project structure

SampleProject

    def get_project_root() -> Path:
    """Returns project root folder."""
    return Path(__file__).parent.parent

    return get_project_root().joinpath(path)

Then simply call the function with the file_path as an argument:

filePath = get_file('com/python/example/source/utils/configManager.py')

And then the usual procedure:

while open(filePath) as f:
