The module makes the code reusable and easy to understand. We're familiar to put a python file inside a folder, and create a __init__.py file under the same folder, then we can easily import the file by import the folder, as the folder is transformed to a python module. We can access a module, variables, files from a subdirectory using two different functions.

Functions such as importlib.import_module() and built-in __import__() can also be used to invoke the import machinery.. Python code is organized in folders called packages containing .py files called modules. Ask Question Asked 10 years, 11 months ago. either pkg.mod or ..mod).If the name is specified in relative terms, then the package argument must be set to the name of the package which is to act as the anchor for resolving the package name (e.g. Initialized from the environment variable PYTHONPATH, plus an installation-dependent default.. As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. Then python will search it in the PYTHONPATH which is a list of directory names, with the same syntax as the shell variable PATH. You can submit pull requests and issues for discussion.
