如何利用python 读取配置文件

import configparser
 
cf = configparser.ConfigParser() # 实例化
 
# read(filename) 读取文件
filename = cf.read(r'G:\api_test\configfile.ini',encoding='utf-8')
 
# sections() 得到所有的section，以列表形式返回
sec = cf.sections()
print(sec)
 
# 得到section下的所有option
opt = cf.options("mysql")
print(opt)
 
# items 得到section的所有键值对
value = cf.items("mysql")
print(value)
print(dict(value)) # 转成字典类型
 
# get(section,option) 得到section中的option值，返回string/int类型的结果
mysql_host = cf.get("mysql","host")
mysql_password = cf.getint("mysql","port")
print(mysql_host,mysql_password)

import configparser
 
conf = configparser.ConfigParser()
conf.read(r'G:\api_test\configfile.ini',encoding='utf-8')
 
conf.set("code", "code", "6666")  # 修改指定section 的option
conf.set("code", "age", "123")  # 增加指定section 的option
conf.has_section("code")
conf.has_option("code","age")
#conf.remove_section("test")
#conf.remove_option("test","haha")
if 'test' not in conf.sections():
    conf.add_section("test")  # 增加section
    conf.set("test", "haha", "123")  # 给新增的section 写入option
file = open(r'G:\api_test\configfile.ini', 'w',encoding='utf-8')
conf.write(file)
file.close()

import configparser
import os
 
class ReadConfig():
    def __init__(self, filepath=None):
 
        root_dir = os.path.dirname(os.path.abspath('.'))        # 获取项目主路径
        # print("打印",root_dir)
        configpath = os.path.join(root_dir, "configfile.ini")  # 拼接路径
        # print("得到的路径为",configpath)
        self.cf = configparser.RawConfigParser()
        self.cf.read(configpath,encoding='utf-8')
    def get_cookie(self, param):
        value = self.cf.get("cookie", param)
        return value
    def get_sheet(self,param):
        value = self.cf.get("sheet",param)
        return value
    def get_mysql(self,param):
        value = self.cf.get("mysql",param)
        return value
    def get_code(self,param):
