3. What is the utility of built – in function help()?
Answer – The documentation for modules, functions, classes, keywords, etc. is shown using the help() function. The interactive help tool launches on the console if we don’t pass an argument to the help function.

4. What is docstrings? How are they useful?
Answer – A Python module, class, function, or method is documented with a string known as a “docstring” so that programmers may understand what it does without having to learn the specifics of how it is implemented. Additionally, it is usual practice to automatically produce online (html) documentation from docstrings.

5. What happens when Python encounters an import statement in a program?
Answer – If the module is found in the search path when the interpreter comes across an import statement, it is imported. The interpreter uses a search path, which is a list of directories, when importing a module.

6. What is the procedure to create own library/package in Python?
Answer – You need to give your Python package a special name. No two Python packages with an existing name can have the same name. The name of your package must be the same for both the parent folder and the subfolder. There are packages and parameter names in the setup.py file.

7. Why is a package attached to site-package folder of Python installation?
Answer – What function does the Python installation’s site-packages folder serve? The default location and folder from which the Python interpreter imports all user-defined packages and libraries is called site-package. So, in order to import any package using the import command, we must attach it to the Python installation’s site-package folder.
