一、元组

（1）元组的创建

tu = (11,22,33,)或者tu = tupel((11,22,33))

（2）元组常用的操作

def count(self, value): # real signature unknown; restored from __doc__    """ T.count(value) -> integer -- return number of occurrences of value """    #计数

def index(self, value, start=None, stop=None): # real signature unknown; restored from __doc__    """    T.index(value, [start, [stop]]) -> integer -- return first index of value.    Raises ValueError if the value is not present.    """    #索引

二、字典

（1）字典的创建

dic = {"k1":"v1","k2":"v2"} 或者 dic = dict(k1 = "v1",k2 = "v2")

（2）字典的常用操作

def clear(self): # real signature unknown; restored from __doc__    """ D.clear() -> None.  Remove all items from D. """    #清空字典

def copy(self): # real signature unknown; restored from __doc__    """ D.copy() -> a shallow copy of D """    #复制：浅的复制

def fromkeys(*args, **kwargs): # real signature unknown    """ Returns a new dict with keys from iterable and values equal to value. """    #序列设定KEY,附加值，生成新的字典

def get(self, k, d=None): # real signature unknown; restored from __doc__    """ D.get(k[,d]) -> D[k] if k in D, else d.  d defaults to None. """    #当一个KEY不存在字典中时，返回一个默认直none或设置赋一个新的值，当KEY存在时，不生效

def items(self): # real signature unknown; restored from __doc__    """ D.items() -> a set-like object providing a view on D‘s items """#输出字典中的对象 

def keys(self): # real signature unknown; restored from __doc__    """ D.keys() -> a set-like object providing a view on D‘s keys """    #输出字典中的KEY

def pop(self, k, d=None): # real signature unknown; restored from __doc__    """    D.pop(k[,d]) -> v, remove specified key and return the corresponding value.    If key is not found, d is returned if given, otherwise KeyError is raised    """#指定删除一个KEY

def popitem(self): # real signature unknown; restored from __doc__    """    D.popitem() -> (k, v), remove and return some (key, value) pair as a    2-tuple; but raise KeyError if D is empty.    """#随机删除一个KEY，并反回删除的KEY

def setdefault(self, k, d=None): # real signature unknown; restored from __doc__    """ D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D """#给KEY设默认值

def update(self, E=None, **F): # known special case of dict.update    """    D.update([E, ]**F) -> None.  Update D from dict/iterable E and F.    If E is present and has a .keys() method, then does:  for k in E: D[k] = E[k]    If E is present and lacks a .keys() method, then does:  for k, v in E: D[k] = v    In either case, this is followed by: for k in F:  D[k] = F[k]    """#更新字典

def values(self): # real signature unknown; restored from __doc__    """ D.values() -> an object providing a view on D‘s values """#输出字典KEY的值
