3.3 对于section的读取操作

文件：

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-bin=py-mysql-bin
character-set-server=utf8
collation-server=utf8_general_ci
log-error=/var/log/mysqld.log
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
[client]
default-character-set=utf8

1.判断section是否存在

import configparser
machine = configparser.ConfigParser()
machine.read('new.ini',encoding = 'utf-8')
judge = machine.has_section('mysqld')
print(judge)

2.输出所有sections 返回类型为列表

import configparser
machine = configparser.ConfigParser()
machine.read('new.ini',encoding = 'utf-8')
result = machine.sections()
print(result)
