When information about a type is needed you can use:
my_list = [] dir(my_list) gets:
['__add__', '__class__', '__contains__', '__delattr__', '__delitem__', '__delslice__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getslice__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__setslice__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'] or:
dir(my_list)[36:] gets:
['append', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'] Now, in the documentation of Python information can be found about these functions, but I would like to get info about these functions in the terminal/command-line. How should this be done?

We use the getsource() method of inspect module to get the source code of the function. Returns the text of the source code for an object. The argument may be a module, class, method, function, traceback, frame, or code object.
Python dir() Function The dir() function returns all properties and methods of the specified object, without the values. This function will return all the properties and methods, even built-in properties which are default for all object.
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, or topics, type "modules", "keywords", or "topics".
Return Vype: The following displays the help on the builtin print method on the Python interactive shell. Help on built-in function print in module builtins: print(...) Prints the values to a stream, or to sys.
In python: help(my_list.append) for example, will give you the docstring of the function.
>>> my_list = [] >>> help(my_list.append) Help on built-in function append: append(...) L.append(object) -- append object to end If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
