A parent directory can have many subdirectories; thus, many subdirectories can share the same parent directory. Not only do you need a __init__.py file in each source directory, but also one for the parent directory that links the sub-directories.

Import a File in a Subdirectory (Python 3.3 and Up) Python versions 3.3 and higher allow easy imports of modules in subdirectories of the current script's directory. Python modules can get access to code from another module by importing the file/function using import. For Python this root is the current directory or the directory where the module is located. During an absolute import, Python browses through the parent folder (subword_count in this case) and locates the file or module containing the function of interest (CountWords). This is when you need to import that other python file or package into your current code. The actual location of your files is right there in your code. Add the parent directory of the Nth predecessor of the current module to sys.path.

Relative paths are interpreted relative to the current working directory, not the directory of the Path object. 2. This field is required. If the parent directories do not exist, it will also create them. If you are compiling protos as part of a Python package (which is the case in most non-trivial Python projects), the interpreter's current working directory is the directory of your main module (suppose the directory is mypackage/), and modules in the package must either use fully-qualified absolute imports (e.g. they all contain __init__.py, then you can use from ..bar_dir import bar If the directories aren’t Python […] Implicit relative imports have been deprecated in Python … In prepend and append import-modes, if pytest finds a "a/b/test_module.py" test file while recursing into the filesystem it determines the import name as follows:. i.e. The absolute path of the notebook or directory.
