class list(object) |  list() -> new empty list |  list(iterable) -> new list initialized from iterable's items |   |  Methods defined here: |   |  __add__(...) |      x.__add__(y) <==> x+y |   |  __contains__(...) |      x.__contains__(y) <==> y in x |   |  __delitem__(...) |      x.__delitem__(y) <==> del x[y] |   |  __delslice__(...) |      x.__delslice__(i, j) <==> del x[i:j] |       |      Use of negative indices is not supported. |   |  __eq__(...) |      x.__eq__(y) <==> x==y |   |  __ge__(...) |      x.__ge__(y) <==> x>=y |   |  __getattribute__(...) |      x.__getattribute__('name') <==> x.name |   |  __getitem__(...) |      x.__getitem__(y) <==> x[y] |   |  __getslice__(...) |      x.__getslice__(i, j) <==> x[i:j] |       |      Use of negative indices is not supported. |   |  __gt__(...) |      x.__gt__(y) <==> x>y |   |  __iadd__(...) |      x.__iadd__(y) <==> x+=y |   |  __imul__(...) |      x.__imul__(y) <==> x*=y |   |  __init__(...) |      x.__init__(...) initializes x; see x.__class__.__doc__ for signature |   |  __iter__(...) |      x.__iter__() <==> iter(x) |   |  __le__(...) |      x.__le__(y) <==> x<=y |   |  __len__(...) |      x.__len__() <==> len(x) |   |  __lt__(...) |      x.__lt__(y) <==> x<y |   |  __mul__(...) |      x.__mul__(n) <==> x*n |   |  __ne__(...) |      x.__ne__(y) <==> x!=y |   |  __repr__(...) |      x.__repr__() <==> repr(x) |   |  __reversed__(...) |      L.__reversed__() -- return a reverse iterator over the list |   |  __rmul__(...) |      x.__rmul__(n) <==> n*x |   |  __setitem__(...) |      x.__setitem__(i, y) <==> x[i]=y |   |  __setslice__(...) |      x.__setslice__(i, j, y) <==> x[i:j]=y |       |      Use  of negative indices is not supported. |   |  __sizeof__(...) |      L.__sizeof__() -- size of L in memory, in bytes |   |  append(...) |      L.append(object) -- append object to end |   |  count(...) |      L.count(value) -> integer -- return number of occurrences of value |   |  extend(...) |      L.extend(iterable) -- extend list by appending elements from the iterable |   |  index(...) |      L.index(value, [start, [stop]]) -> integer -- return first index of value. |      Raises ValueError if the value is not present. |   |  insert(...) |      L.insert(index, object) -- insert object before index |   |  pop(...) |      L.pop([index]) -> item -- remove and return item at index (default last). |      Raises IndexError if list is empty or index is out of range. |   |  remove(...) |      L.remove(value) -- remove first occurrence of value. |      Raises ValueError if the value is not present. |   |  reverse(...) |      L.reverse() -- reverse *IN PLACE* |   |  sort(...) |      L.sort(cmp=None, key=None, reverse=False) -- stable sort *IN PLACE*; |      cmp(x, y) -> -1, 0, 1 |   |  ---------------------------------------------------------------------- |  Data and other attributes defined here: |   |  __hash__ = None |   |  __new__ = <built-in method __new__ of type object> |      T.__new__(S, ...) -> a new object with type S, a subtype of T
