python代码如下:
# python中set函数基本用法示例(编程之家 jb51.cc整理)
class set(object):
set() -> new empty set object
set(iterable) -> new set object
Build an unordered collection of unique elements.
def add(self,*args,**kwargs):
添加
Add an element to a set.
This has no effect if the element is already present.
pass
def clear(self,**kwargs):
清除
Remove all elements from this set.
pass
def copy(self,**kwargs):
浅拷贝
Return a shallow copy of a set.
pass
def difference(self,**kwargs):
比较
Return the difference of two or more sets as a new set.
(i.e. all elements that are in this set but not the others.)
pass
def difference_update(self,**kwargs):
Remove all elements of another set from this set.
pass
def discard(self,**kwargs):
删除
Remove an element from a set if it is a member.
If the element is not a member,do nothing.
pass
def intersection(self,**kwargs):
Return the intersection of two sets as a new set.
(i.e. all elements that are in both sets.)
pass
def intersection_update(self,**kwargs):
Update a set with the intersection of itself and another.
pass
def isdisjoint(self,**kwargs):
Return True if two sets have a null intersection.
pass
def issubset(self,**kwargs):
Report whether another set contains this set.
pass
def issuperset(self,**kwargs):
Report whether this set contains another set.
pass
def pop(self,**kwargs):
Remove and return an arbitrary set element.
Raises KeyError if the set is empty.
pass
def remove(self,**kwargs):
Remove an element from a set; it must be a member.
If the element is not a member,raise a KeyError.
pass
def symmetric_difference(self,**kwargs):
Return the symmetric difference of two sets as a new set.
(i.e. all elements that are in exactly one of the sets.)
pass
def symmetric_difference_update(self,**kwargs):
Update a set with the symmetric difference of itself and another.
pass
def union(self,**kwargs):
Return the union of sets as a new set.
(i.e. all elements that are in either set.)
pass
def update(self,**kwargs):
Update a set with the union of itself and others.
pass
def __and__(self,**kwargs):
Return self&value.
pass
def __contains__(self,y):
x.__contains__(y) <==> y in x.
pass
def __eq__(self,**kwargs):
Return self==value.
pass
def __getattribute__(self,**kwargs):
Return getattr(self,name).
pass
def __ge__(self,**kwargs):
Return self>=value.
pass
def __gt__(self,**kwargs):
Return self>value.
pass
def __iand__(self,**kwargs):
Return self&=value.
pass
def __init__(self,seq=()): # known special case of set.__init__
set() -> new empty set object
set(iterable) -> new set object
Build an unordered collection of unique elements.
# (copied from class doc)
pass
def __ior__(self,**kwargs):
Return self|=value.
pass
def __isub__(self,**kwargs):
Return self-=value.
pass
def __iter__(self,**kwargs):
Implement iter(self).
pass
def __ixor__(self,**kwargs):
Return self^=value.
pass
def __len__(self,**kwargs):
Return len(self).
pass
def __le__(self,**kwargs):
Return self<=value.
pass
def __lt__(self,**kwargs):
Return self size of S in memory,in bytes
pass
def __sub__(self,**kwargs):
Return self-value.
pass
def __xor__(self,**kwargs):
Return self^value.
pass
__hash__ = None
