Python read and write INI file sample (Python read-write file) _python

Very similar to Java properties file

XML file

Copy Code code as follows:

Db_config.ini
[Baseconf]
host=127.0.0.1
port=3306
User=root
Password=root
Db_name=evaluting_sys
[Concurrent]
Processor=20

Import Sys,os
Import Configparser

Class Db_connector:
def __init__ (self, Config_file_path):
CF = Configparser.configparser ()
Cf.read (Config_file_path)

s = cf.sections ()
print ' section: ', S

o = cf.options ("baseconf")
print ' Options: ', O

v = cf.items ("baseconf")
print ' db: ', V

Db_host = Cf.get ("baseconf", "host")
Db_port = Cf.getint ("baseconf", "Port")
Db_user = Cf.get ("baseconf", "user")
Db_pwd = Cf.get ("baseconf", "password")

Print Db_host, Db_port, Db_user, db_pwd

Cf.set ("baseconf", "Db_pass", "123456")
Cf.write (Open ("Config_file_path", "w"))
if __name__ = = "__main__":
f = Db_connector (".. /conf/db_config.ini ")

Get the result:

Copy Code code as follows:

Section: [' Concurrent ', ' baseconf ']
Options: [' Host ', ' db_name ', ' user ', ' password ', ' Port ']
DB: [(' Host ', ' 127.0.0.1 '), (' db_name ', ' Evaluting_sys '), (' User ', ' root '), (' Password ', ' root '), (' Port ', ' 3306 ')]
127.0.0.1 3306 Root root

A second example

Copy Code code as follows:

Import OS
Import Configparser

def main ():
CP = Configparser.configparser ()
CF = open (U "In.ini")
CP.READFP (CF)

secs = Cp.sections ()
Print cp.sections ()

For sec in secs:
OPTs = cp.options (sec)
For opt in opts:
val = cp.get (sec, opt)
Val + = "Test ..."
Cp.set (sec, opt, Val)

Cp.write (Open ("Out.ini", "w"))

if __name__ = = ' __main__ ':
Main ()
