Python day 6 (3) Python functional programming 1, pythonday
I. Functional Programming Concepts
A function is an encapsulation supported by Python. By splitting a large code segment into a function and calling a function at a layer, we can break down a complex task into a sim
Which programming language, such as python and java, is suitable for AI ?, Python artificial intelligence
Google's AI beat a GO master. It is a way to measure the sudden and rapid development of artificial intelligence. It also reveals how these technologies develop and how they can develop in the future.
Artificial intelligence is a future technology and is cur

been ported on many platforms (modified to make it work on different platforms). If you are careful to avoid using system-dependent features, all your Python programs can run without modification on any of the platforms listed below. These platforms include Linux, Windows, FreeBSD, Macintosh, Solaris, OS/2, Amiga, AROS, as/400, BeOS, os/390, z/OS, Palm OS, QNX, VMS, Psion, Acom RISC OS, VxWorks, PlayStation, sharp Zaurus, Windows CE and even PocketPC
, but is different from a constructor because Python is not new. After the instance is created, the method is invoked before the instantiation call returns the instance.

Batch Processing and python code mixed programming method, batch processing python
Batch processing can be easily mixed with other languages for programming. In addition to being fun, batch processing also has considerable practical value. For example, the windows ruby gem Package Manager uses batch processing and rub
Python-Based Functional Programming Tutorial, python Functions
Many functional articles describe abstract functional technologies such as combinations, pipelines, and higher-order functions. Different in this article, it shows the imperative and non-functional code examples that people write every day, and converts these examples into functional styles.

Python core programming-Chapter 3-exercises, chapter 3 of python
1. This is a feature of python. python first creates an object. When assigning values to a variable, you do not need to define the name and type of the variable. Actually, it uses the variable to reference the
__init__ (self, name, gender, score): super (Student, self). __init__ (name, gender) = ScoreBe sure to super(Student, self).__init__(name, gender) initialize the parent class, otherwise the inherited from Person Student will not name 和 gender . The function super(Student, self) returns the parent class that is inherited by the current class, that is Person , then calls the __init__() method, notes that the self parameter is passed in super() , implicitly passes in, __init__() and
Summarize the usage points of functions in Python programming, and the main points of python
Why use functions
Maximize code reuse and minimize code Redundancy
Process Decomposition
Compile Functions

Protocol version 6th (IPV6) addressing. Of all address families, Af_inet is the most widely used one. Python 2.5 adds support for a Linux socket: af_netlink (no connection [see below]) The socket family allows the IPC between user code and kernel code to use the standard BSD socket interface. Moreover, this approach is more graceful and more secure than cumbersome schemes such as adding new system calls to the operating system, proc file system suppo
Python network programming (twisted-based client programming)
Python's twisted is interesting. It can be used for server programming or client programming. Echo is the simplest example of programming.
The client code is as follow

1. Dictionary
A key cannot correspond to multiple values: when a key conflicts (that is, the dictionary key is assigned a value repeatedly), the last (most recent) value is assigned.
>>> Dict1 = {'foo': 789, 'foo': 'xyz '}>>> Dict1{'Foo': 'xyz '}
