If your python version is 3, then you can use python importlib.util module’s spec_from_file_location, module_from_spec and loader.exec_module function to load and run a python module saved in a python source file.. Below example will load a custom python module that is saved in Test.py file. The name argument specifies what module to import in absolute or relative terms (e.g. Python has different frameworks and open source applications like Django, flask, and Jupyter notebook. If you have a notebook file named server.ipynb, you can import it via: We can understand it as; We imported the file named file1.
