Welcome to Python 3.8's help utility! If this is your first time using Python, you should definitely check out the tutorial on the Internet at https://docs.python.org/3.8/tutorial/. Enter the name of any module, keyword, or topic to get help on writing Python programs and using Python modules. To quit this help utility and return to the interpreter, just type "quit". To get a list of available modules, keywords, symbols, or topics, type "modules", "keywords", "symbols", or "topics". Each module also comes with a one-line summary of what it does; to list the modules whose name or summary contains a given string such as "spam", type "modules spam".
The empty help() method will give you basic information about the python version and about the python interpreter.
You can also check out some of the examples below for more information.
Or you can just type help() to access the python help shell in which you can directly type the object name without including it inside the help() method.
To quit the help method in the python interpreter and return to the python shell, you just need to type quit and press enter or just press CTRL + Q key together.
You can also pass the argument in the string, and it will check if the given string name matches with any of the python modules, method, class, method, keywords, or any other documentation topics. It will return that particular name documentation; otherwise, it will simply return the string documentation.
Try these on a python interpreter.
