python读取ini配置的类封装代码实例

这篇文章主要介绍了python读取ini配置的类封装代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

此为基础封装，未考虑过多异常处理

类

# coding:utf-8
import configparser
import os

class IniCfg():
  def __init__(self):
    self.conf = configparser.ConfigParser()
    self.cfgpath = ''

  def checkSection(self, section):
    try:
      self.conf.items(section)
    except Exception:
      print(">> 无此section，请核对[%s]" % section)
      return None
    return True

  # 读取ini，并获取所有的section名
  def readSectionItems(self, cfgpath):
    if not os.path.isfile(cfgpath):
      print(">> 无此文件，请核对路径[%s]" % cfgpath)
      return None
    self.cfgpath = cfgpath
    self.conf.read(cfgpath, encoding="utf-8")
    return self.conf.sections()

  # 读取一个section，list里面对象是元祖
  def readOneSection(self, section):
    try:
      item = self.conf.items(section)
    except Exception:
      print(">> 无此section，请核对[%s]" % section)
      return None
    return item

  # 读取一个section到字典中
  def prettySecToDic(self, section):
    if not self.checkSection(section):
      return None
    res = {}
    for key, val in self.conf.items(section):
      res[key] = val
    return res

  # 读取所有section到字典中
  def prettySecsToDic(self):
    res_1 = {}
    res_2 = {}
    sections = self.conf.sections()
    for sec in sections:
      for key, val in self.conf.items(sec):
        res_2[key] = val
      res_1[sec] = res_2.copy()
      res_2.clear()
    return res_1

  # 删除一个 section中的一个item（以键值KEY为标识）
  def removeItem(self, section, key):
    if not self.checkSection(section):
      return
    self.conf.remove_option(section, key)

  # 删除整个section这一项
  def removeSection(self, section):
    if not self.checkSection(section):
      return
    self.conf.remove_section(section)

  # 添加一个section
  def addSection(self, section):
    self.conf.add_section(section)

  # 往section添加key和value
  def addItem(self, section, key, value):
    if not self.checkSection(section):
      return
    self.conf.set(section, key, value)

  # 执行write写入, remove和set方法并没有真正的修改ini文件内容，只有当执行conf.write()方法的时候，才会修改ini文件内容
  def actionOperate(self, mode):
    if mode == 'r+':
      conf.write(open(self.cfgpath, "r+", encoding="utf-8"))  # 修改模式
    elif mode == 'w':
      conf.write(open(self.cfgpath, "w"))           # 删除原文件重新写入
    elif mode == 'a':
      conf.write(open(self.cfgpath, "a"))           # 追加模式写入

cfgpath = r'C:\Users\SXF\Desktop\config.ini'

inicfg = IniCfg()
sections = inicfg.readSectionItems(cfgpath)
print(sections)
content = inicfg.readOneSection('chaoji')
print(content)
dic = inicfg.prettySecToDic('chaoji')
print(dic)
dic = inicfg.prettySecsToDic()
print(dic)
inicfg.addSection('chaoji22')

content = inicfg.readOneSection('chaoji')
print(content)

测试ini

[chaoji]
chaoji_username = 123
chaoji_password = 456
[my]
soft_id     = 789
sleeptime     = asd
cnt_count     = zxc
