Python Learning Notes-basic "Sixth Week"--pyyaml & Configparser Modules

Pyyaml Module

Python can also easily handle the Ymal document format, but requires the installation of a module, reference document: Http://pyyaml.org/wiki/PyYAMLDocumentation

Configparser module of common modules

Used to generate and modify common configuration documents, the name of the current module is changed to Configparser in the Python 3.x version.

Here's a look at a lot of the common document formats for software

[DEFAULT] Serveraliveinterval = 45Compression = Yescompressionlevel = 9forwardx11 = yes [Bitbucket.org]user = HG [topsecret.server.c Om]port = 50022forwardx11 = no

What if you want to use Python to generate a document like this?

Import Configparser config = Configparser. Configparser () config["DEFAULT"] = {' Serveraliveinterval ': ' A ',                      ' Compression ': ' Yes ',                     ' compressionlevel ': ' 9 '} config[' bitbucket.org ' = {}config[' bitbucket.org ' [' User '] = ' HG ' config[' topsecret.server.com '] = {}topsecret = config[' topsecret.server.com ']topsecret[' Host Port ' = ' 50022 '     # mutates the parsertopsecret[' ForwardX11 '] = ' no ' c3/># same hereconfig[' DEFAULT ' [' ForwardX11 '] = ' yes ' with open (' Example.ini ', ' W ') as ConfigFile:   config.write ( ConfigFile)

When you're done, you can read it again.
