Python network resources + python Manual

How to learn Python + how to effectively utilize Python-related network resources + How to take advantage of Python's own manual (Python Manual)almost forgot to say, before looking at all the content below, for the Python version does not understand, please be sure to check this first:

Collation summarizes the differences between Python2 (Python 2.x version) and Python3 (Python 3.x version)

Then, depending on the situation, choose the Python version that you need before it comes to the question of how to learn.

"Learn the basic process of Python"

1. Learn the basics of Python first

Recommended Information:

1. Python's third-party library

Python's third-party library, a huge number of functions, but it is because too much, it is impossible to summarize one by one.

But Python's official website has been sorted out and put here:

Http://pypi.python.org/pypi?%3Aaction=index

The page is very inconvenient because of too many libraries.

Here are the categories to view:

Http://pypi.python.org/pypi?%3Aaction=browse

If you need some aspects of the function, you can go to the above two addresses, find out if there is no ready-made library, if any, directly to use, than you developed from scratch, to be more efficient.

2. Summary of the various Python information

This includes a summary of the Python language I wrote, which consists of two main pieces:

(1) Python learning experience and experience

Summarize some of the understanding in the process of tossing python, and some of the details of the considerations.

(2) Crifan Python library: crifanlib.py

Use some of the usual python functions and organize them for you and others.

Especially a lot of network functions, when you use, you will know that will save you a lot of energy.

"How to use Python to bring your own manual Python Manual"

One of the most important things to note about reference materials is that for many unfamiliar Python functions, the best way to learn is to go to Python's own manual to find it first.

And Python comes with the manual, after you install Python, (my Windows environment, through EXE installed Python version 2.7), you can start->python 27-> python mannuals:

For example, involves network programming, need to use URLLIB2 this module, want to understand URLLIB2.

So the first step, you can first go through manual to find URLLIB2:

And then look at the syntax:

urllib2. Urlopen (url[, data][, timeout] )

Open the URL url, which can be either a string or a RequestObject.

Warning

HTTPS requests do does not have any verification of the server ' s certificate.

Data may are a string specifying additional data to send to the server, or None if no such data is needed. Currently HTTP requests is the only ones, which use data; The HTTP request would be a POST instead of a GET when the data parameter is provided. Data should is a buffer in the standard application/x-www-form-urlencoded format. The urllib.urlencode () function takes a mapping or sequence of 2-tuples and returns a string in this format. URLLIB2 module sends http/1.1 requests withConnection:closeheader included.

The optional timeout parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not Specified, the global default timeout setting would be used). This actually only works for HTTP, HTTPS and FTP connections.

This function returns a File-like object with the additional methods:

• Geturl () -return The URL of the resource retrieved, commonly used to determine if a redirect was followed
• info () -return The meta-information of the page, such as headers, in the form of a mimetools. Message instance (see Quick Reference to HTTP Headers)

Raises Urlerror on errors.

Note that None is returned if no handler handles the request (though the default installed global Openerd Irector uses unknownhandler to ensure this never happens).

In addition, default installed Proxyhandler makes sure the requests is handled through the proxy when they is s Et.

Changed in version 2.6:timeout was added.

So, to have a basic understanding of it, then go to the online detailed look at other people's sample code.

This helps you to learn this library function quickly and accurately.

At the very least, I have learned and learned so much about many of the python built-in library functions.
