all of attributes and methods related to a special type

[akbarza]

hi
how can I see all attributes and methods related to a special type? for example, I want to see all methods and attributes related to lists, how can I do it?
I write in idle dir(list) and it shows some, but there is not del in the given list, but del can be used with list type to omit element(s) of it:

dir(list)

Output:
['__add__', '__class__', '__class_getitem__', '__contains__', '__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getstate__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'clear', 'copy', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']

'del' in dir(list)

Output:
False

mylist=[1,2,3,4,5]
del mylist[2]
mylist

Output:
[1, 2, 4, 5]

del mylist[0:2]
mylist

Output:
[4, 5]

thanks
