從配置檔案中讀取程式所需的引數等資訊。步驟：
1、匯入： import configparser
2、開啟配置檔案，配置檔案test.conf要和py檔案在同一目錄下，否則需指定配置檔案所在的目錄：
cf = configparser.configparser()
cf.read("test.conf")3、讀配置檔案資訊
db2_database = cf.get("db2", "database")
db2_hostname = cf.get("db2", "hostname")
db2_port = cf.get("db2", "port")
db2_protocol = cf.get("db2", "protocol")
db2_uid = cf.get("db2", "uid")
db2_pwd = cf.get("db2", "pwd")注意：cf.get返回的是字串，如果要返回整型可用sf.getint
完整的指令碼如下
#-*- encoding: utf-8 -*-
import configparser,string
import ibm_db
# read config file
cf = configparser.configparser()
cf.read("test.conf")
db2_database = cf.get("db2", "database")
db2_hostname = cf.get("db2", "hostname")
db2_port = cf.get("db2", "port")
db2_protocol = cf.get("db2", "protocol")
db2_uid = cf.get("db2", "uid")
db2_pwd = cf.get("db2", "pwd")
配置檔案格式如下
[db2]
database=dbname
hostname=hostname
port=50000
protocol=tcpip
uid=uid
pwd=pwd
[concurrent]
thread=10
processor=20
