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
