The configparse of the key modules of Python learning---

Configparse modules are commonly used to generate and modify common configuration documents

Build configuration module: write in a dictionary

Import Configparserconfig = Configparser. Configparser () config["DEFAULT"] = {' Serveraliveinterval ': ' A ',                     ' Compression ': ' Yes ',                     ' compressionlevel ': ' 9 '}config[' user '] = {}config[' user ' [' user '] = ' hhh ' config[' ssh '] = {}topsecret = config[' ssh ']topsecret[' Host Port '] = ' 50022 '  # mutates the parsertopsecret[' ForwardX11 '] = ' no '  # same hereconfig[' DEFAULT ' [' ForwardX11 '] = ' yes ' With open (' Example.ini ', ' W ') as ConfigFile:    config.write (ConfigFile)

Read configuration: Config.sections ()

Import Configparserconfig = Configparser. Configparser () config.read (' Example.ini ')                  print (Config.sections ())                     # [' USER ', ' SSH '], default not Dayin[default] Module print (config[' user ')                        # <section:user>print (config[' user ' [' user '])                # Hgprint (Config.defaults ())                     # Print default module, print out an ordered dictionary of print (config.has_section (' USER '))            # True ordereddictprint (config[' default '] [' CompressionLevel '] # 9   # Print the default module, print out an ordered dictionary ordereddict#, like a dictionary, prints only key information for key in config[' default ':    # print ( Key, V)  error, too many values to unpack (expected 2)    print (key)

Delete Entire module: Remove, file cannot be modified, only overwrite, can be re-written to new file

Import Configparserconfig = Configparser. Configparser () config.read (' Example.ini ') # file cannot be modified, only overwritten, can be re-written to new file Config.remove_section (' SSH ') with open (' Example.ini ', ' W ', encoding= ' utf-8 ') as F:    Config.write (f) Print (Config.sections ())

Delete an element under a module

Import Configparserconfig = Configparser. Configparser () config.read (' Example.ini ') print (config.has_option (' User ', ' user ') config.remove_option (' User ', ' User ') print (config.has_option (' User ', ' user ')) with open (' Example.ini ', ' W ', encoding= ' utf-8 ') as F:    Config.write (f)

To modify the configuration:

Import Configparserconfig = Configparser. Configparser () config.read (' Example.ini ') print (config[' user ' [' user ']) config.set (' User ', ' user ', ' FTL ') print ( config[' user ' [' user ']) with open (' Example.ini ', ' W ', encoding= ' utf-8 ') as F:    Config.write (f)
