Bytearray对象是使用内置函数创建的bytearray()。 缓冲区对象不直接受Python语法支持,但可以通过调用内置函数来创建buffer()。他们不支持连接或重复。 xrange类型的对象类似于缓冲区,因为没有特定的语法来创建它们,但是它们是使用xrange()函数创建的。它们不支持切片,串联或重复使用in,not in,min()或max()对它们是无...

list 是能够被更改,list的构造方式有:1. [], 2. [a],[a,b,c], 3. [x for x in iterable] 4. list() or list(iterable). list的另一个操作:排序,sort(*,key=None,reverse=None) tuple tuple 是不能够更改的序列型,能够实现所有通用操作 ...
If you have repeated keys across your dictionaries, besides managing your dictionaries as one, you can also take advantage of the internal list of mappings to define some sort of access priority. Because of this feature, ChainMap objects are great for handling multiple contexts. For example, say...

Namedtuples support natural tuple comparison, which allows for sorting and ordering operations. By using a lambda function as a key, you can sort namedtuples by any of their fields. In this case, cities are sorted by population, illustrating the flexibility of namedtuples in handling organized ...
A method is a function that performs some sort of operation on an object when the method is invoked. Attributes and methods are accessed using the dot (.) operator, as shown in the following example: a = 3 + 4j # Create a complex number r = a.real # Get the real part (an ...
