YAMLOverview: it is an intuitive data serialization format that can be recognized by computers.In YAML, the structure is represented by indentation, and consecutive items are represented by minus signs "-". The key/value pairs in the map structure are separated by colons.YAML can also be used to describe the abbreviation Syntax of several lines of data with the same structure. arrays are included with '[]', and hash is included.Example:

Because the strings returned by the Internal interface of the company support two forms: PhP array and XML; the PHP array Python cannot be used directly, but the XML string format is not standard, therefore, standard module Parsing is not supported. [It is not standard that the names of some nodes start with numbers]. Therefore, write a simple step to parse the file for interface testing.

In Python, we typically use the tools provided in URLLIB2 to complete HTTP requests, such as post data to the server. Typically, all data is URL-encoded and Content-type is set to application/x-www-form-urlencoded. However, in some special cases (such as server restrictions that do not allow this type of data submission) or when uploading files, a post submission in multipart/form-data format is required.At

The example in this article describes the way Python formats CSS files. Share to everyone for your reference. The implementation methods are as follows:
Import string, sys
import Re, Stringio
tab=4
def format (ss):
f = open (ss, "R")
data = F.read ()
F . Close ()
Dlen = len (data)
i = 0
buf = Stringio.stringio ()
start = 0 while
i if __name__ = = ' __main__ ':
If Len (sys.argv) = = 1:
Because the company's internal interface returns the string support 2 kinds of forms: PHP array, XML; results php array python can not be used directly, and XML string format is not standard, so also can not use the standard module parsing. "Non-standard place is the name of some node will be the beginning of the number", so write a simple step to parse the file, used to do interface testing.
