# python中set函数基本用法示例(四海网整理)
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, *args, **kwargs):
"""清除"""
""" Remove all elements from this set. """
pass
def copy(self, *args, **kwargs):
"""浅拷贝"""
""" Return a shallow copy of a set. """
pass
def difference(self, *args, **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, *args, **kwargs):
""" Remove all elements of another set from this set. """
pass
def discard(self, *args, **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, *args, **kwargs):
"""
Return the intersection of two sets as a new set.
(i.e. all elements that are in both sets.)
"""
pass

""" Report whether another set contains this set. """
pass
def issuperset(self, *args, **kwargs):
""" Report whether this set contains another set. """
pass
def pop(self, *args, **kwargs):
"""
Remove and return an arbitrary set element.
Raises KeyError if the set is empty.
"""
pass
def remove(self, *args, **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, *args, **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, *args, **kwargs):
""" Update a set with the symmetric difference of itself and another. """

Return the union of sets as a new set.
(i.e. all elements that are in either set.)
